Crepis (Greek for Sandal; application obscure). Compositae. A large group of annual, biennial and perennial herbs, a few of which are now and then grown in outdoor gardens for the showy flowers.

Much like Hieracium, differing mostly in the simpler involucre, white soft pappus, and beaked achene: Lvs. radical and cauline, the former mostly runcinate, repand or pinnatisect, the latter mostly clasping: heads pedunculate, solitary or paniculate, all the florets perfect and ligulate, the rays yellow, orange or red: fr. a smooth achene.— Perhaps 250 species in the north temperate zone, some of them weedy and widely dispersed. Among the cult, kinds is C. sibirica, which resembles a sow-thistle in habit, and has corymbs of reddish blue fls. about the size of a hawkweed, or a small dandelion. It is one of the coarser border plants, and rare. Rather light, sandy soil, and full exposure to the sun are essentials to the welfare of this plant. It is contented in a rather dry position, either in the rockery, or in the border. It is prop, by division. A common plant on the moss of English thatched cottages is C. virens, a yellow-fld. plant, resembling a dandelion. C. rubra appears to be the commonest annual species cult, abroad. CH
