SCALY GRINDELIA.
Grindelia squarrosa (Pursh) Dunal.

Range.—Scaly grindelia (fig. 18) has a wider distribution than the gum plant, being quite common on the plains and prairies from the Saskatchewan to Minnesota, south to Texas and Mexico, and westward to California.

Description.—This species is very similar to the gum plant, with the exception that it is smaller and does not have the gummy appearance of the former. The slender, erect stems are from 1 to 2 feet high and somewhat sparingly branched near the top. The branches near the flower heads appear to be somewhat more reddish than in the species previously mentioned. In this species, also, the leaves are not borne on stalks, but are somewhat clasping at the base, and they are longer (about 2 inches long), not rigid, thinner, and more prominently toothed. The flowers are also very similar to those of the gum plant, but are smaller, the scales narrower, and the recurved tips longer and more slender.

Parts used.—The leaves and flowering tops are collected with those of the gum plant, Grindelia robusta.
