 flowers also fertile, with funnelform 4-toothed corolla and linear-oblong obtuse

 smooth, obovate-oblong, obscurely obcompressed, the terminal areola larger and 

 more evident, at least in the perfect flowers: heads small, axillary. — Calyn^ 

 mandray Torr. & Gray, Fl. ii. 262. 



E. Candida. A spau or two high, slender, and with commonly simple branches, silvery 

 white throughout with appressed wool : heads usually few in a foliose-involucrate cluster 

 and sessile or nearly so in the axils of the spatulate or lanceolate leaves. — C'ahjmmandra

§ 1. Receptacle subulate ; its pluriserial and well-imbricated bracts merely 

 concave, subtending the loose akenes. — Gifola, Cass. 



P. GermAitica, L. (Cotton-Rose, Hkrba Ijipia of the old herbalists.) A spau to a foot 

 high, erect, thickly beset with lanceolate commonly erect leaves, terminated by a capituli-

 proliferous: heads ovate-oblong; its bracts ovate-lanceolate, acuminate. — 11. Dan. t. 2787.

§ 2. Receptacle somewhat obconical or convex ; its deeply concave or boat-

F. depressa, Gray. Diffusely branched from the root, depressed-spreading: internodes

 on the back : akenes obovate, smooth, sometimes the uppermost bracteate ones also with 

 pappus. — Proc. Am. Acad. xix. 3. — Sau Bernardino Co., S. California, in the desert at
