| Chrysanthemum coccineum, Willd. (Pyrethrum roseum, Bieb., not Web. & Mohr. P. hybridum, Hort.). Fig. 933. Glabrous perennial, 1-2 ft. high: st. usually unbranched, rarely branched at the top: lvs. thin, dark green, or in dried specimens dark brown: involucral scales with a brown margin; rays white or red in such shades as pink, carmine, rose, lilac, and crimson, and sometimes tipped yellow, but never wholly yellow. Caucasus, Persia.—This species is the most important and variable of all the hardy herbaceous kinds. There have been perhaps 700 named horticultural varieties. There is an anemone-fld. form with a high disk. The species is also cult. in Calif. and France for insect powder. C. atrosanguineum, Hort., is said to be a good horticultural variety with dark crimson fls. The C. roseum of Weber & Mohr being a tenable name, Hoffmann proposes Ascherson's name, C. Marschallii, for the P. roseum of Bieberstein; but Willdenow's C. coccineum is here retained. | | Chrysanthemum coccineum, Willd. (Pyrethrum roseum, Bieb., not Web. & Mohr. P. hybridum, Hort.).
