Composite—Rudbeckia. 243 
deeply coloured and spreading not deflexed more numerous ray- 
florets, is said to be an improved variety of this species, or 
perhaps a hybrid between it and some other. A native of the 
southern United States, flowering in Summer. 
R. aspérrima and R. angustifolia are closely allied species : 
the former with pale rose flowers, in which the florets are 
narrow, numerous, and toothed at the tip; and the latter with 
narrow leaves and purplish flowers. 
2. BR. Drumméndii, syn. Lepachys columnaris, Obeliscaria 
pulchérrima, ete. (fig. 131).—A very showy species in some of 
its varieties. The pinnatisect leaves and elevated disk are the 
most conspicuous features in this species. The ray-florets are 
bright yellow, or orange-red and yellow, and in one variety 
they are fewer in number and broader than those represented 
in the figure. A native of Texas, growing from 2 to 3 feet 
high, and flowering in August. 
3. R. falgida, syn. R. chrysoméla.— distinct species about 
2 feet high with leafy peduncles and yellow flowers about 2 
inches in diameter with a purplish brown centre. Ray-florets 
numerous, emarginate. A North American species flowering 
in July and August. 
R. élegans of dwarfer habit, and R. grandiflora with larger 
flowers, are near the last. The latter is rather tender. 
18. COREOPSIS (Calliépsis). 
Annual or perennial showy usually glabrous herbs, natives 
of North America. Leaves simple or pinnate, opposite. 
Involucral bracts in two rows, the outer spreading and the 
inner combined at the base and erect. Receptacle furnished 
with linear chaffy scales. Fruit-achenes incurved, or flat on 
one side and convex on the other, 2-awned or truncate at the 
apex. The flowers of some species are strikingly beautiful, 
having a distinct brightly coloured eye, hence the application 
of the second name to some of them; and Coredpsis is a com- 
pound of xépus, a bug, and dys, resemblance, from the appear- 
ance of the 2-awned achenes. 
Annual Species. 
1. C. tinetoria. — A slender species about 2 feet high.
