 tinct, filiform. In general habit it recalls the Scorpioides, from 

 which it differs, at first sight, in the colour of the pappus.

De characteribus analyticis, vide supra. 



Hab. in St. Vincent: in silvis montium, alt. 600 900 m, 

 Juli. 1899, H. H. et G. W. Smith n. 922 (K, KU). 



From a remark on the label of the specimen cited (KU): 

 Vernonia = St Vincent, Anderson it appears as if already 

 Anderson had collected the species.

The subsection thus defined includes a great number of 

 species from the Andes (V. baccharoides H. B. K. and its allies), 

 from Brazil (V. polyanthes Less, and its allies), and from Mexico 

 (V. lanceolaris DC. and its allies). It matches the species-

 ded, further, his Havanenses except V. pallescens Gleason, 

 his Paniculatce dichotomce, and, may be, some of his Panicu- 

 latce umbelliformes . The West Indian representatives are out- 

 lying species of apparently very ancient origin. They may 

 have originated from Columbia, where allied forms still live. 



The West Indian species can be divided into two smaller 

 groups, one including V. havanensis DC. and its allies, the 

 second V. menthcefolia (Poepp. ) Less. To the latter species 

 Gleason attributes a higher taxonomic rank, making it the
