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. asperrima 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. R. Drummondii, syn. Lepachys columnaris, Obeiiscaria 

 pulcherrima, etc. (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. fulgida, syn. R. chrysomela. A 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. 6legans of dwarfer habit, and R. grandiftora with larger 

 flowers, are near the last. The latter is rather tender. 



18. COREOPSIS (Galliopsis). 



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 Coreopsis is a com- 

 pound of /ro/oty, a bug, and ox/ay, resemblance, from the appear- 

 ance of the 2-awned achenes. 



Annual Species. 



1. G. tinctoria. A slender species about 2 feet high.
