Studies on the West Indian Vernonieae, with one new species from 
Mexico 
HENRY ALLAN GLEASON 
Seven years ago, in the Revision of the North American 
Vernonieae,* forty-three species and one variety of Vernonia were 
recognized from the West Indies, together with several species of 
other genera. Since that time, the New York Botanical Garden 
has been actively engaged in the systematic exploration of these 
islands, especially Cuba, and has accumulated much valuable 
material. Director N. L. Britton has recently extended to me 
the facilities of the Garden, and has given me the opportunity to 
examine the new material in this tribe of Carduaceae. The 
results of this study are herewith presented. 
Of the forty-four species and varieties recognized in the re- 
vision, three have been found untenable and are reduced to 
synonymy: V. sublanata Gleason, V. Thomae Benth., and V. 
Sintenisii (Urban) Gleason. The variety has been raised to 
specific rank. Four old species, not recognized in the revision, 
are shown by the recent collections to be distinct, and are admitted 
as species: V. acuminata Lessing, V. Ottonis Sch.-Bip., V. Wrightu 
Sch.-Bip., and V. fruticosa (L.) Sw. For the identification of the 
latter, we are indebted to Dr. Urban, who has also described a new 
species, V. Tuerckheimii. The collections at the Garden, supple- 
mented by some material loaned by the Gray Herbarium and the 
Missouri Botanical Garden, are also found to contain Seventeen
