Square-Bud Primrose. Day Primrose. Creamcups (Meriolix spinulosa) has yellow cup-shaped flowers which last only twenty-four hours but which are open during the day. It may readily be distinguished from other evening-primroses by the slender woody stems which soon become reddish or straw-colored. The stems grow 1-1½ ft. high with clusters of flowers at the top. The flowers are nearly two inches broad and have four petals. The short, broad sepals are winged on the back and make the buds appear square and pointed.

Another distinguishing feature is the disk-shaped stigma which is sometimes yellow and sometimes black or dark brown. In the evening-primroses previously mentioned, the stigma is divided into four narrow lobes. The plants grow on gravelly hillsides from Arkansas to Mexico. The slender capsules are over an inch long. Several other day primroses are found in the state. They are all sometimes grouped with the œnotheras.

Large-Flowered or Lindheimer’s Gaura (Gaura lindheimeri) is, like other members of this group, called kisses and wild honeysuckle because of its sweet fragrance. Most of them produce an abundance of nectar and make excellent honey plants. This is the handsomest member of the group in Texas and is known in cultivation as a hardy plant. It is native to the prairies of Southeast Texas and Louisiana and blooms from March to May.

The four white petals have the group characteristic of turning fan-wise toward the upper side of the flower, and the 8 long stamens and the long style hang toward the lower part. Only a few flowers open at one time around the spike, but numerous buds are densely crowded above the open flowers. This plant has erect-ascending branches and grows 2-5 feet high.

Prairie Gaura. Wild Honeysuckle (Gaura brachycarpa) sometimes grows 2-3 feet high, but is usually much lower. With favorable rains, the flowering spikes grow quite long. This gaura may be recognized by its stalkless 4-angled seed capsules. It blooms on Texas prairies in April and May. Many other gauras are found in the state.

DOGWOOD FAMILY (Cornaceae)

Leaves usually opposite; sepals usually 4, calyx tube joined to the ovary; petals usually 4, or absent; stamens 4, alternate with the petals; ovary inferior; fruit a drupe.

Flowering Dogwood (Cornus florida) grows from Massachusetts to Ontario, Texas, and Mexico, but few people realize that it grows very luxuriantly and is widespread in the woods of East Texas. The beauty of the dogwood is not in the flowers, as one might expect, but in the four broad white floral leaves (bracts) which surround the flower-cluster. These bracts are a creamy white but are often tinged with pink. The minute greenish-white flowers have four petals and bloom in March before the leaves appear. The oblong scarlet fruits, about half an inch long, ripen in the fall.

It is said that dogwood gets its name from the fact that the bark of an English dogwood was used to treat mangy dogs. Another source for the name is given in a recent magazine which shows a photograph of a section of wood from a dogwood tree. By means of the growth rings of the tree, the section depicted the head of a swimming dog. Among the useful substances obtained from the tree are quinine from all parts, scarlet dye from the bark, and wood for tools. Enough quinine is obtained by chewing the twigs to ward off malarial fever.

Rough-Leaved Cornel. Small-Flowered Dogwood (Cornus asperifolia) is hardly recognized as a dogwood because it does not have showy floral bracts. The rough leaves become very lovely in the fall as the veins take on a reddish-purple color. It is a very common shrub in thickets along streams or in moist ground from Texas to Southern Ontario. The flowers bloom in Texas from April to June, and the white fruits mature in the fall. The fruits are about ¼ inch in diameter and contain 2 seeds with a stony coat which is covered by a thin pulp.

The dogwood family includes several other trees and shrubs which are common in Texas. Black gum (Nyssa sylvatica) has 2-3 blue oval fruits about half an inch long in a cluster. It is one of the first trees in East Texas whose foliage takes on an autumnal coloring. Lindheimer’s garrya (Garrya lindheimeri), an evergreen shrub with thick leathery leaves, is very abundant in the hills of Central and West Texas. It bears dense clusters of small blue berries less than ¼ inch in diameter.

CARROT FAMILY (Umbelliferae)

Furrowed stems; leaves usually much divided, sheathing at the base; sepals 5, calyx tube joined to ovary; petals 5; stamens 5; ovary inferior; fruit 2-celled, prominently ribbed and often with resin canals.

Prairie Lace. Dwarf Queen Anne’s Lace (Bifora americana) is the pride of the North Texas prairie in late April and May. It is also found in Oklahoma and Arkansas. In favorable seasons it grows in great masses with the Indian blankets and the false coreopsis. The umbrella-clusters of white flowers are very showy. The plants do not have oil tubes, as do most members of the carrot family, and so lack the strong scent common to many.

It usually grows about a foot high and is widely branched at the top. The leaves are finely divided with numerous thread-like divisions. The flowers are one-fourth inch broad and have five notched petals which are broader than long. The fruits have two ball-shaped divisions, each about one-eighth inch in diameter and faintly ridged.

False Purple Thistle. Eryngo (Eryngium leavenworthii) is not a true thistle, but it is popularly known as one. The ancient Greeks had the same idea, for the name “Eryngium” is their name for a kind of thistle. Correctly speaking it is a purple carrot, as it belongs to a large group of the carrot family, some of which are widely cultivated abroad for their striking purple foliage. The flowers are clustered in an oblong head, quite different from the dainty flower clusters of Queen Anne’s lace. Other common names of this group include sea-holly, rattlesnake master, and button snake-root, the two latter from their accredited property of curing snake-bites. Candelabrum plant is a name sometimes given which is very appropriate because of its branching habit of growth.

The plants grow one to three feet high, usually in dense masses along roadsides and fields and on prairies from Central Texas to Kansas. In August the gray-green foliage of the plants is quite conspicuous against darker greens, but it gradually takes on a royal purple hue. Few plants can rival it for beauty in late August and September. The dense heads of purple flowers with their long, slender dark-blue stamens add to the vividness. The dried plants are often kept for winter decoration, but the purple does not remain so intense.

The stems are branched at the top, the flower heads growing on short stalks in the forks of the branches. The deeply lobed leaves clasp the stem, the leaf segments bearing many spiny-teeth. A tuft of small, rigid, spiny leaves grows out of the top of the flower head.

Several eryngoes are found in the state. The yucca-leaved eryngo (Eryngium aquaticum) grows in the summer in sandy areas or low grounds from Texas to Minnesota and Connecticut. It bears little resemblance in habit of growth or coloring to the purple thistle. Most of the long leaves are clustered at the base, and a stout flower stalk bears at the top several head-like clusters of white flowers.

The carrot family is a large group of plants, most of which have lacy, fern-like leaves and dainty umbrella-clusters of small flowers and fruit which separates into two ribbed 1-seeded divisions. The plants are usually rich in oil tubes, and some contain deadly poisons.

Beggar’s Ticks. Seed-Ticks. Bird’s Nest Carrot (Daucus pusillus) is probably more familiar in fruit than in flower. The clusters of seeds resemble a bird’s nest. The fact that the seeds are covered with several rows of barbed prickles makes them very difficult to remove from clothing. Their presence in wool renders it inferior in quality. It is very abundant throughout the state from April to June and occurs in most of the Southern and Western States.

The small white flowers grow in a dense, lace-like cluster at the top of slender stems 1-2 ft. high. The leaves are finely divided. The flower cluster is long-stalked and is surrounded by a circle of the green leaves; thus the flowers as well as the seeds have a nest-like appearance.

Wild Carrot. Queen Anne’s Lace (Daucus carota), the ancestor of the garden carrot, was introduced from Europe and may be found in scattered places over the state. It is a larger plant than the beggar’s ticks, with very wide-spreading and dainty flower clusters. It does not bloom until summer.

Wild Dill. Prairie Parsley (Pleiotaenia nuttallii) is a conspicuous plant on prairies throughout the state and ranges to Michigan and Alabama. The flowers bloom in April and May, and the seeds mature and fall in June and July. The stiff, stout stems, commonly two feet high, become dry and brown but remain standing through the winter months. The upper leaves are not divided so much as the lower, which are deeply divided and have broad segments. The flowers are small and greenish-yellow and grow in clusters about 2 inches broad.

The foliage and seeds were used for seasoning by pioneers. It is very much like the cultivated dill (Anethum graveolens), a native of Southeastern Europe. The latter is taller and has leaves with threadlike divisions.

Other well-known members of the carrot family include the parsnip, parsley, myrrh, chervil, caraway, and celery. The well-known poison hemlock (Conium maculatum), by which Socrates met his death, is a native of Europe but may now be found in North and South America. It grows in great abundance along the streams of the Edwards Plateau between Fredricksburg and Austin.

HEATH FAMILY (Ericaceae)

Herbs or shrubs; sepals 4-5; corolla urn-shaped or cylindric, 4-5-lobed; stamens 8 or 10; anthers opening by terminal pores; ovary superior or inferior.

Tree-Huckleberry. Farkleberry (Batodendron arboreum) is also known as upland-huckleberry, sparkleberry, and gooseberry. The name is Greek and means “blackberry tree.” The huckleberries are often placed in a family separate from other heaths. The tree-huckleberry is a shrub or small tree, very abundant in the woods of East Texas and the Southern States. The dainty, drooping sprays of white bell-shaped flowers remind one of the lily-of-the-valley. The shining oval leaves are short-stalked, 1-2 in. long. The black berries are not edible.

Well-known members of the heath family include the trailing arbutus, cranberry, blueberry, bean-berry, winter-green, rhododendron, and azalea. Thickets of the pink azalea or swamp-honeysuckle (Azalea nudiflora) occur in a few places in East Texas. In the mountains of Southwest Texas may be found the arbutus-tree, madroña, or naked Indian, so called because of its red wood and scaling bark. Its small, red fleshy fruits look like strawberries. Stagger-bush (Neopieris mariana) is a common shrub in swampy places.

PRIMROSE FAMILY (Primulaceae)

Leaves often basal; sepals usually 5, often leafy; corolla tubular, 5-lobed; stamens 5, opposite the petals; ovary superior; fruit a capsule.

Texas Water-Pimpernel. Brookweed (Samolus cuneatus) is a plant found wherever springs or moist ledges occur in limestone hills of Texas. The plants have a basal rosette of broad rounded leaves. The slender stems are 6-12 inches high and bear a few leaves which are narrowed at the base. The 5-lobed white flowers are short and bell-shaped and appear from April to September. The pink water-pimpernel (Samolus ebracteatus) grows in sandy soil along the coast.

Shooting Star (Dodecatheon stanfieldia) is a rare plant and should be afforded protection. It is found in rich, moist soil from Central Texas to Louisiana. The flowers are very much like those of Dodecatheon meadia but are larger and have broader petals.

The primrose family is represented in horticulture by many primroses from Asia, cyclamens from Greece to Syria, and the cowslip from Europe. The scarlet pimpernel (Anagallis arvensis) is found on sandy prairies in South Texas in the spring.

EBONY FAMILY (Ebenaceae)

Trees or shrubs; leaves usually leathery; calyx 3-11-lobed; petals united, 3-7; stamens 6-14, or more; ovary superior.

Mexican Persimmon (Diospyros texana) is also called ’possum plum, “chapote,” and black persimmon. It is a shrub or small tree found in river-valleys and on limestone hills from Central Texas to Mexico. It may be easily recognized by its smooth, light-gray bark, small leaves, and creamy heath-like flowers. The bell-shaped flowers are in dense clusters on the tree which has pollen-bearing flowers, whereas the seed-bearing flowers, which grow on a separate tree, are larger and fewer in number. The black fruits ripen in August, when the pulp becomes juicy but somewhat insipid.

The black wood is hard and, like other species of ebony, takes an excellent polish. It is used for making tools. The Mexicans use a black dye obtained from the fruits in dyeing sheep-skins. The common persimmon (Diospyros virginiana) is found wild from Connecticut to East Texas, where the sprouts are vicious pests in plowed lands.

GENTIAN FAMILY (Gentianaceae)

Leaves opposite; calyx usually tubular, 5-lobed; petals united at base, 4-12; stamens as many as petals; ovary superior.

Mountain Pink. Showy Centaury (Erythraea beyrichii) grows on gravelly limestone hills in Texas and Arkansas. The stems are branched near the base and often form hemispherical clumps a foot in diameter which are covered with pink flowers in June. The plants are being rapidly exterminated for ornamental purposes, for they are very showy and the flowers will last two weeks or more. The flowers have a united tubular corolla with 5 lobes.

The scientific name is from the Greek meaning “red.” The flowers of some species are red, but those in Texas are pink. The Texan centaury (Erythraea texense) is a very small plant with small flowers. It is found from Texas to Missouri in June and July. Buckley’s centaury or pink gentian (Erythraea calycosa) is found in moist soil in the western part of the state. It is a tall, slender plant 1-2 ft. high. It ranges from Missouri to Mexico. The centaury plants were formerly valued as a medicine for fever. They were gathered and dried at flowering time.

Purple Gentian. Bluebell (Eustoma russellianum) is also called Russell’s eustoma, Texas bluebell, blue gentian, blue marsh lily, and bosque blue gentian. The latter name is used in El Paso, where the purple gentian grows on the flood plain of the Rio Grande River. It is one of the loveliest flowers in the state, sometimes occurring in great profusion on moist prairies from Mexico to Colorado and Louisiana. It is especially abundant in Southeast Texas, where it is gathered in wholesale quantities by florists. It is an excellent cut-plant, the flowers lasting for several days and new buds continually opening.

Few people have had success in transplanting the purple gentian into their gardens. Only recently has there been a report of seeds successfully germinated. It is said that soaking for 48 hours in water will produce germination. Each flower produces a number of very minute seeds.

The large, bell-shaped flowers, 2-3 inches broad, are a bluish-purple; in fading, they spread widely and take on more of the blue tinge. They are constricted into a short narrow tube at the base. Inside, the flowers are marked with yellow at the base and have purple markings in the throat. The five stamens with large anthers are attached to the corolla tube. At the time the pollen is shed, the anthers lie in a horizontal position around the style. The stigmas are interesting. There are two diamond-shaped lobes which are erect until they are ready to receive pollen, and then they take a horizontal position. The calyx has five linear lobes which are united at the base with a colorless membrane. The oblong capsules are about half an inch long.

The plants are very smooth and are erect, with a few erect branches. The leaves are ovate-oblong and are usually 1-2½ inches long.

“Eustoma” means “open mouth”, referring to the large throat of the flower. The smaller bluebell in Southern Texas and Northern Mexico is Eustoma gracile.

Pink Texas Star. Prairie Sabbatia (Sabbatia campestris) is also known as meadow pink, rose pink, pink prairie gentian, marsh pink, and sea star. It ranges from Missouri and Kansas to Texas and is found on moist prairies throughout Central Texas from April to June. It is particularly abundant on southern coastal prairies where it makes a showy landscape display with phlox, coreopsis, and other plants in March and April. The sabbatias are named in honor of two Italian botanists, L. and C. Sabbati.

The plants are low, 3-12 inches high, and have wing-angled stems and short smooth leaves about ½-1¼ inches long. The flowers are about 1½ inches broad, much larger than those of the mountain pink, and more cup-shaped. They are usually deep pink in color, but purplish-pink and white forms may occasionally be noted. Around the throat are yellow, star-shaped markings over the white base of the petals. The long, linear calyx lobes are quite conspicuous when the flower is in bud or after the corolla has wilted.

DOGBANE FAMILY (Apocynaceae)

Plants with milky juice; sepals usually 5; corolla tubular, 5-lobed; stamens usually 5, inserted on corolla tube and alternate with the lobes; ovary superior; fruit mostly of 2 spreading follicles.

Blue Texas Star. Texas Dogbane. Blue-Star (Amsonia texana) belongs to a group named in honor of Charles Amson, a colonial physician. The stems are usually unbranched, 8-12 inches high, and are covered with narrow linear leaves. Like that of other amsonias, the tubular throat is lined with white hairs. The name of twin-pods might be given to the amsonias. The numerous seeds are borne in two narrow, erect pods which are united at the base and split along the inner sides. The pods are 3-4 inches long. The plant is perennial, growing in low clumps on limestone hillsides of Texas. The plants in North Texas form a conspicuous bluish-green line on low hills, when the flowers bloom in late March and April.

The oleander, periwinkle, and vinca are well-known members of the dogbane family. They all have a milky sap which is quite poisonous in the oleander, Indian hemp, and others. “Bane” is the common word in Northern Europe for “murderer” and is applied to poisonous plants.

MILKWEED FAMILY (Asclepiadaceae)

Leaves usually opposite or whorled; sepals 5; petals 5, usually reflexed and with a 5-lobed crown; stamens 5, the pollen united into 1 or 2 waxy masses in each sac; carpels 2, free except for the united disk-like stigma.

Green-Flowered Milkweed. Silkweed (Asclepiodora decumbens) is a widespread plant from Arkansas to Utah and Northern Mexico. It is found on the central and western plains, blooming in early spring and sometimes again in the fall. The stout, leafy stems, topped by the ball-shaped heads of flowers form conspicuous clumps about a foot high. The flowers have a sweet nectar which draws many insect visitors. They bloom in April and early May, and the large warty pods mature in a few weeks. As the seeds bear a tuft of hairs at one end, they are easily scattered by the wind and other agents. It is one of the first plants to appear on burned-over areas.

The milkweeds get their name from the bitter milky sap. The flowers are quite different from other flowers in that there is a crown between the petals and the stamens. In many the pollen is borne in two pear-shaped masses with a thread-like connection. In the green-flowered milkweed, purple hoods are attached to the crown and hang over the pollen-sacs.

Butterfly-Weed. Pleurisy-Root (Asclepias tuberosa) is a well-known plant in dry fields from Maine and Ontario to Northern Mexico. In Texas it is found in the sandy areas of the eastern and central parts. It blooms in the late spring and summer. Other common names include orange milkweed, orange-root, Indian posy, and orange swallow-wort. The leaves are poisonous to stock, but the honey is not considered poisonous. The monarch butterfly is a voracious feeder on the plant. It was at one time valued for its medicinal properties, but is now little used. Several plants are known by the common name of “swallow-wort” and are so called because they bloom in the spring when the swallows appear.

The leafy stems often grow one to two feet high. At the top of the stem are several clusters of small orange-colored flowers. The petals hang down when the pollen is ready to be shed. There is a crown of five erect, orange-colored hoods around the flat stigma.

DICHONDRA FAMILY (Dichondraceae)

Herbs with creeping stems; sepals 5; corolla bell-shaped, 5-lobed; stamens 5; carpels 2, separate.

Carolina Dichondra. Ground Ivy (Dichondra carolinensis) is, of course, not even kin to the ivy, but it does form a green carpet over the ground in places. It is widely scattered in the state and in many other localities. The greenish-white flowers are small and inconspicuous under the round leaves and are almost buried in the soil. The leaves are about an inch broad and are slender stalked. The plant is a perennial which is often hard to remove from lawns. The silvery-leaved dichondra (Dichondra argentea) occurs in West Texas.

DODDER FAMILY (Cuscutaceae)

Pretty Dodder. Love Vine. Strangle-Weed (Cuscuta indecora) may be noted in conspicuous orange or gold masses covering other plants. It is a leafless parasitic vine bearing small clusters of white flowers. The flowers are less than one fourth inch broad and have the petal-tips turned inward. There are many dodders in the state, and each kind is parasitic only on certain plants. The pretty dodder attacks the wild verbena and other herbs and low shrubs from Illinois to Texas and other parts of America.

MORNING-GLORY FAMILY (Convolvulaceae)

Plants twining or erect; sepals 5; corolla mostly funnelform, 5-lobed; stamens 5, on corolla tube; ovary superior; fruit usually a ball-shaped capsule separating into 2-4 lobes.

Texas Bindweed (Convolvulus hermannioides) has small white morning-glory flowers with a dark-red center. They are seldom more than an inch broad. The spreading or twining vines reach a length of several feet. The leaves are very variable in shape and often have spreading lobes at each side of the base like the hoary bindweed (Convolvulus incanus). Both grow on Texas plains, but the hoary bindweed is widely distributed from Kansas and Arkansas to Mexico. The Texas bindweed may be distinguished by the ear-like projections at the base of the sepals. The flowers bloom from April to August.

Purple Morning-Glory. Bindweed. Tie-Vine (Ipomoea trifida) is a lovely but pernicious vine of Texas, Mexico, and tropical America. The roots are perennial and very difficult to eradicate from cotton and corn fields. It blooms from spring to fall, the flowers opening only in the morning. The morning-glory group is very large, and many showy forms are found in Texas. The sweet potato (Ipomoea batatas) and others are valued for their tuberous roots.

PHLOX FAMILY (Polemoniaceae)

Mostly annual and perennial herbs; calyx 5-lobed; corolla tubular, 5-lobed; ovary usually 3-celled; style often 3-parted; stamens 5, inserted on corolla-tube; capsules small.

Standing Cypress. Red Gilia (Gilia rubra) might also be called torch flowers, for the tall spikes with their masses of red tubular flowers make flaming spots of color on the edges of the post oak woods in May and June. It is sometimes known as Indian plume, Texas plume, or red Texas star.

The plants are usually unbranched and grow two to three feet high; however, if the top of the stem is removed or injured near the time of flowering, it will branch into several flowering spikes. The stems are pale green and quite leafy with the finely dissected leaves. The narrow tubular flowers are over an inch long and have broad spreading lobes which, on their inner surface, are a pale orange-red dotted with a darker red. The flowers, which resemble those of the cypress vine, are closely clustered on the stem, those at the top opening first. The capsules are nearly an inch long and contain numerous papery seeds.

Blue Gilia. Golden Eye (Gilia rigidula), differing markedly from the red gilia in the shape of the flowers, has a short, broadly flaring corolla with a conspicuous yellow center. The flowers are nearly an inch broad. The plants are perennial and are often widely branched at the base, forming clumps nearly a foot broad. The blue gilia is found on hills and stony plains from Central Texas to Mexico and New Mexico and blooms from March to October.

White Gilia. Long-Flowered Gilia (Gilia longiflora) has slender, erect stems, 1-2 feet high, terminated by a flat-topped cluster of tubular white flowers. The flowers have a narrow tube, about 1½ inches long, and 5 broad, spreading lobes. The leaves have threadlike divisions. The plants are very showy when they are in bloom and are especially abundant in sandy regions of Northwest Texas in the late summer and fall.

Few flower groups show such a decided red, white, and blue as the gilias. The group is a large one, mostly of Western North America, and is named in honor of the Spanish botanist, Philipp Salvador Gil. Some of the gilias are known in cultivation and are considered hardy plants of easy culture. The standing cypress may be grown from seeds planted in August or September, or plants may be transplanted in the spring.

Drummond’s Phlox (Phlox drummondii) has rightly been called “Texan pride.” A drive late in April through the post oak sandy region east of Austin to the Brazos River and southeast to Victoria will disclose it in all its glory. The seeds were collected by Thomas Drummond in 1834 and sent to W. J. Hooker in the spring of 1835. Hooker, an eminent botanist, described it from the plants grown from those seeds in the Kew Gardens in London. According to his description, the plants were mostly of a brilliant rose-red with more or less purple in the flowers of some plants and darker red eyes in nearly all. It is quite probable that Drummond collected his seeds in the vicinity of Gonzales, the western limit of his Texas trip, where today wild phloxes which match his description occur in great profusion. The seeds collected may have included some from hybrid plants, as red phloxes with a white eye are found on the eastern edge of the red-phlox area, and the dark-eyed purple and red are found on its western limits in close proximity to the “phlox purple” variety.

The plant has long been a horticultural favorite, and more than 200 varieties have been described, few of which excel the native varieties in size or coloring.

Purple Phlox (Phlox drummondii-purple varieties) grows in sandy soil in Central Texas. The variety with the white throat and red-star eye is common in the southeastern part of the state. It is especially abundant in Wilson and Karnes Counties, where extensive masses of purple may be noted in open sandy places among mesquite and post oak trees. This is a very vigorous phlox and produces large stems and flowers. Studies are being made to determine whether these purple phloxes are varieties of Drummond’s phlox or should be called by other names.

The variety with the purple throat and the two white marks at the base of each corolla lobe grows northwest of the range of the red-flowered Drummond’s phlox. It blooms from April to June and seems to withstand cold better than any of the annual phloxes except the dwarf phlox.

Berlandier’s Phlox (Phlox glabriflora) differs from Drummond’s phlox in many particulars. The flowers are usually a bluish-lavender which at a distance suggests the wild verbena. Like the other phloxes on this page, it has both stem and leaves clothed with scattered, long, soft hairs. The large corolla is marked with white at the base of the lobes and has a short, smooth tube. The vigorous plants branch profusely and often form masses two and three feet broad. This phlox may be found on sandy prairies south of Kingsville and west of Hebbronville in the winter and spring months but is at its best in February and March. It was first collected by Louis Berlandier at several places along the southern coast in 1828 and 1829.

Heller’s Phlox (Phlox helleri) is a close relative of Berlandier’s phlox but has a hairy corolla-tube, smaller flowers, and shorter leaves. It is found from March to May in sand near the coast around Copano, Aransas, and Nueces bays.

Slender Phlox (Phlox tharpii) has a long, hairy corolla-tube, and the slender stems are usually unbranched. Only four flowers are borne in a cluster. It is very abundant in Frio and Dimmit Counties in April. Theodore Roosevelt, in describing a peccary hunt south of Uvalde in April, 1904, mentions these fields of purple.

Roemer’s Phlox (Phlox roemeriana) has lovely flowers which vary in color from deep rose to phlox purple or pink. It is the only annual phlox marked with yellow around the eye or throat. Its large capsule, containing 12 or 15 seeds, is another conspicuous feature and shows its relationship with the perennial phloxes of West Texas. It forms a lovely display with bluebonnets and low prairie spider-worts in the limestone hill region in April and early May.

Dwarf Phlox (Phlox tenuis) is the smallest and most widely distributed of the annual phloxes, ranging from the south-central coast to Louisiana and into Southern Oklahoma. It is found on the coastal prairie and in sandy soil along the edges of post oak woods from March to May. The plants are usually six to eight inches high and unbranched, but branched varieties are known. The flowers are about half an inch broad, with narrow lobes which are marked with two reddish-purple lines at their base.

Prairie Phlox. Prairie Sweet William (Phlox pilosa) has a delightful fragrance common in lesser degrees to many of the phloxes. The widespread prairie phlox was named in 1753 from plants taken to France from Virginia. The stems are low and have a few opposite leaves which are pointed and widely spreading. The flat-topped clusters of pale pink, blue, white, or purple flowers bloom in March and April in Texas. The stems and flower clusters are clothed with soft hairs.

Large-Flowered Prairie Phlox (Phlox villosissima) grows in a strange environment for a phlox. Charles Wright found it in 1849 on the gravelly bars of the Nueces River, where it still grows. It is also found on other rivers in Southwest Texas. It has long, woody roots reaching toward the necessary moisture. The flowers are very large, and only a few are open at a time. It differs from the prairie phlox in its shorter and more numerous leaves, its larger flowers with their broader lobes, and alternate branches in the flower cluster. The prairie phloxes are perennial and are easily grown in Southwest gardens.

WATER-LEAF FAMILY (Hydrophyllaceae)

Flowers usually in curled clusters; calyx deeply 5-lobed; petals united, usually 5; stamens 5, on corolla-tube; ovary superior; styles 2.

Baby Blue-Eyes. Flannel Breeches (Nemophila phacelioides) forms a lovely carpet on banks and in moist woods near the prairie regions of Texas and Arkansas. The dainty flowers are about one inch broad, with 5 broadly-spreading lobes of lavender, paler at the base. The leaves are divided into 5-9 broad segments which are irregularly toothed. It is not known in cultivation, but a similar plant from California is used to cover beds in which bulbs are planted.

Purple Phacelia (Phacelia patuliflora) is a low, spreading annual growing on sandy prairies in the southern part of the state. “Patuliflora” means “spreading flower” and refers to the royal purple corollas which are widely spreading and nearly an inch broad. It is the handsomest phacelia among the fifteen or more species found in the state. It blooms from February to May.

Blue nama (Nama ovatum) is a water-leaf growing in ponds and streams of East Texas and blooming in the summer. It has lovely sky-blue flowers nearly an inch broad and spiny stems. Sand bells (Nama hispidum) has small, reddish-purple, bell-shaped corollas.

Blue Curls. Fiddle-Neck (Phacelia congesta) is also known as spider-flower, caterpillars, snail-flower, and wild heliotrope. It has curled flower clusters and lavender-blue flowers very much like those of some of the heliotropes and borages. A California borage is also called fiddle-neck. The flowers are tubular at the base with 5 broadly spreading lobes. The 5 spreading stamens extending from the flowers are responsible for the name of “spider-flower.”

The erect, unbranched stems may be seen on gravelly limestone slopes or in open woods from Central to Southwestern Texas. The large, thin leaves are finely divided and clothed with soft hairs. In woods the plants may grow 1½-2 ft. high, but on rocky slopes they are seldom more than a foot high. The flowers bloom in April and May, a long blooming season resulting from the numerous flowers which open as the curling stems unfold. It is an annual plant which does well in cultivation and makes a lovely addition to the flower garden.

Nearly a hundred phacelias are found in Western North America. The name is from the Greek meaning “cluster.” Most of them are showy plants, but few are known in cultivation.

BORAGE FAMILY (Borraginaceae)

Leaves usually alternate; flowers often in curled clusters; sepals 5; petals 5, united; stamens 5, on corolla-tube; ovary often deeply 4-lobed; fruit a drupe or of 4 nutlets.

Southern Heliotrope (Cochranea anchusaefolia) grows in limestone soil from Central Texas to Florida and tropical America. It may often be found from spring to fall in the shelter of mesquite or prickly pear. The white-flowered sea-heliotrope (Heliotropium curassavicum) is very abundant in saline soil in South and West Texas. Plains heliotrope (Heliotropium tenellum) does not have curled clusters of flowers but has a few small white ones borne on short branches. It is widespread in the South-central United States.

Bindweed Heliotrope (Heliotropium convolvulaceum) has white flowers quite similar to those of the bindweed, about one inch broad. It is found in sandy soil in South and West Texas to California and Nebraska from spring to fall. The plant has widely branching stems, about a foot long, and the foliage is somewhat rough-hairy. The heliotropes get their name from Greek words which mean “sunturning.”

Golden Puccoon. Narrow-Leaved Puccoon (Lithospermum linearifolium) is another harbinger of spring on the prairies. The scattered plants may be found throughout Texas to British Columbia and Indiana. Several slender stems grow from a long, thick black root. The plant gets its name from the Greek word meaning “stone-seed” and refers to the hard nutlets of the fruit. In the narrow-leaved puccoon, the nutlets are ovoid, white, shining, and more or less pitted. The flowers have a narrow tube with 5 spreading lobes which have crinkled margins.

Orange Puccoon (Lithospermum gmelinii) is a striking woodland plant of the Eastern States which is widespread in East Texas. It can be easily identified by its showy yellow-orange flowers. The clustered stems, 1-1½ feet high, grow from a deep root. It blooms in April and May.

Most of the puccoons have a red root from which a dye is obtained. Some of the European forms have blue flowers and are known in cultivation.
