 next to which De Candolle properly places it. May not B, 

 aphylla DC. 1. c. p. 424, be a leafless var. of this? Pappus 

 elongated, lax, stramineous. In the glomerated var. the 

 female capitula have the involucre much longer, and the inner 

 scales particularly, than the specimens with solitary capitula. 

 It will perhaps prove to be a distinct species.

Pappus pale tawny. De Candolle describes the leaves which 

 are nearly an inch long, as obtuse, but they are character- 

 ized by Sprengel as acute, and even mucronate.
