Blake — New and Noteworthy Compositae 17 
generally included in Vernonia, to generic rank, distinguishing 
the group from Vernonia by its inflorescence, the few (1-5)-flowered 
heads, and the frequently deciduous inner phyllaries. This separa- 
tion, while possible if only the North American species of Vernonia 
are considered, breaks down completely if the whole range of 
variation in the genus is taken into view. Thus, there are several 
African species with deciduous inner phyllaries, constituting the 
section Strobocalyx as treated by Oliver & Hiern in the Flora of 
Tropical Africa, iii. 267 (1877). Some species of this section have 
4-6-flowered, others many-flowered heads. In South America 
there are several species with 4—6-flowered heads, for instance 
V. apiculata Mart. and V. hexantha Sch. Bip., with persistent 
phyllaries and a habit and inflorescence utterly different from that 
of the species included by Gleason in Eremosis, which is said by 
him to be a strictly North American genus, although some of the 
African species are precisely similar in habit, inflorescence, in- 
volucre, and number of flowers. The lack of any definite concomi- 
tant characters by which Eremosis can be distinguished as a genus 
necessitates its inclusion as a section in Vernonia, and the following 
four species should be transferred to that genus. To comply with 
International Rules, Latin diagnoses are given of the new species 
described by Dr. Gleason.
