A veiy natural subsection, easily recognized by the large 

 heads, flowers and anthers, and, above all, b}' its glabrous 

 achenes. It shows no relationship with other West Indian 

 subsections, but is allied to V. glabrata Less, and other Bra- 

 zilian species. It is a remarkable fact that the allies of F. 

 glabrata do not occur in North Brazil nor in Gu3'ana. Some 

 species belonging here have been found, however, in the 

 Andes of Bolivia, viz. V. robusta Rusby, V. sid)acuminata 

 HiERON. (= V. obtusata Less.) and V. velascensis Hieron. 



Gleason, having, of course, recognized the subsection, 

 ill his »Revision» named it Fruticosce, supposing Vernonia 

 fruticosa (L.) Sw. to belong here. Recenth'- he has found 

 that the latter species is to be removed from this subsection, 

 and he now calls the subsection Sagrceance, which name I 

 have adopted here, as I had originally used it myself just in 

 the same sense. 



Nearly all species of the subsection are imperfectly 

 known, the material collected being very meagre. Continued 

 collections are badly needed to supplv dates for a defini- 

 tive delimination of the species, as well as for their frequence 

 and distribution. 



The distinctions of the species which belong here will 

 appear from the following key.
