Flowers about ¾′ in diameter, on long slender hairy pedicels, in broad more or less villose corymbs; calyx-tube narrowly obconic, more or less villose or nearly glabrous, the lobes long, narrow, acuminate, glandular with minute dark glands, glabrous on the outer surface, slightly villose on the inner surface; stamens usually 10, occasionally 8—12; anthers pale yellow; styles 2—3, surrounded at the base by a broad ring of hoary tomentum. Fruit ripening at the end of September and often remaining on the branches for several weeks longer, on erect slender pedicels, in broad open many-fruited usually slightly villose clusters, globose, often hairy at the ends until nearly ripe, crimson, very lustrous, ¼′—⅓′ in diameter; calyx large and conspicuous, the lobes coarsely serrate, reflexed and persistent; flesh thin, dark yellow, dry and mealy; nutlets 2 or 3, about ¼′ long and wide, broad and rounded at the ends, the ventral cavities deep and irregular.
A tree, occasionally 15° high, with a tall stem 5′—6′ in diameter, covered with pale close bark, stout wide-spreading branches forming an open rather irregular head, and stout slightly zigzag glabrous light chestnut-brown very lustrous branchlets, becoming dull reddish brown in their second year, and armed with numerous slender usually curved very sharp bright chestnut-brown shining spines 2½′—4′ long.
Distribution. Western Vermont (near Middlebury, Addison County); central and western New York; southern Ontario (near Toronto); northeastern Illinois (Barrington County); and eastern Pennsylvania (Bucks and Northampton Counties).

Leaves broad-obovate to ovate, gradually narrowed below to the cuneate entire base, coarsely serrate above with minute glandular teeth, and often incisely lobed toward the acute apex, nearly fully grown and coated above and on the midrib and veins below with short pale hairs when the flowers open in May, and at maturity thin, glabrous, dark green and lustrous above, paler below, 1′—2′ long, and ½′—1½′ wide; petioles slender, wing-margined above, sparingly glandular, villose early in the season, becoming glabrous, ½′—¾′ in length; leaves at the end of vigorous shoots broad-obovate, incisely lobed at the broad apex, often deeply divided into lateral lobes, or occasionally 3-lobed, 3′—4′ long, and 2′—3′ wide. Flowers ½′—7/12′ in diameter, on long slender glabrous pedicels, in broad glabrous corymbs, with linear caducous bracts and bractlets; calyx-tube broadly obconic, glabrous, the lobes gradually narrowed from a broad base, entire or occasionally minutely dentate, acute and bright red at apex, glabrous on the outer surface, villose on the inner surface; stamens 10 or rarely 5 by abortion; anthers small, pale rose color; styles 2—5, surrounded at base by tufts of long pale hairs. Fruit ripening and falling in August and September, on slender pedicels, in compact, many-fruited drooping clusters, short-oblong, truncate at apex, black and lustrous, very rarely chestnut-colored (f. badia Sarg.), about ½′ long; calyx persistent; flesh thick, sweet and succulent, light yellow; nutlets usually 5, about ¼′ long, narrowed at base, broad and rounded at apex, ridged on the back with a narrow ridge, the ventral cavities irregular, small and shallow.
A tree, 30°—40° high, with a long trunk 18′—20′ in diameter, stout branches spreading and ascending and forming a compact round-topped head, and slender rigid glabrous bright red or orange-red lustrous branchlets unarmed, or armed with straight or slightly curved blunt or rarely acute bright red ultimately ashy gray spines ⅓′—1′ long; often shrubby and spreading into wide thickets.

151. Cratægus rivularis Nutt.
Leaves lanceolate to narrowly oblong-obovate or elliptic, acute, acuminate or abruptly acuminate at apex, gradually narrowed and concave-cuneate at the long entire base, and very finely crenately serrate above with glandular teeth, when they unfold tinged with red, villose above and coated below with matted pale hairs, more than half grown when the flowers open late in May and then hairy on the midrib and veins above and pale and glabrous below, and at maturity thin, dull bluish green and smooth on the upper surface, pale yellow-green on the lower surface, about 2′ long and ¾′ wide, with a slender yellow midrib and 3 or 4 pairs of thin obscure primary veins; petioles slender, slightly winged at apex, at first villose, becoming glabrous and rose-colored below the middle, and about ½′ in length; leaves at the end of vigorous shoots often rhombic, coarsely serrate, often slightly incisely lobed, coriaceous, 3′ long, and 2′ wide, with a stout broadly winged petiole.
