Abstract

Described from Angasima-tepui in Edo. Bolívar, Venezuela is a new species of Stomatochaeta, a generic segregate of Stenopadus. The distinctions between these two genera are briefly discussed and a key to the new species, Stomatochaeta acuminata, and the other species of Stomatochaeta is given. Bilabiate flowers are reported for the first time in Glossarion, which formerly was thought to have only ligulate flowers. Guaicaia, erected to house a single species with bilabiate flowers but otherwise similar in critical features to the reportedly ligulate Glossarion, is reduced to synonymy. Accordingly, the new combination Glossarion bilabiatum is proposed. An emended generic description of Glossarion and a key to its species are presented.
