This diploid (2n = 18) is widespread across temperate North America, except in southeastern states, where perhaps just adventive. Some colls. may need to be rechecked for other species. C. pratericola has narrow leaves that lack secondary veins, but larger leaves are 3-nerved from the base. Similar leaves (more or less linear and often unlobed) are typical of C. pallescens Standl. of the southern Great Plains, C. dessicatum A. Nelson of more western states, and C. foggii H.A. Wahl. of northeastern states, all of which may be expected in Ky., at least as waifs (Y). C. pratericola may also be confused with the "lanceolatum" variant of album, which does have secondary veins, and no leaves 3-nerved from the base.
