(Vol. 03, 2000-12) Moutabea Gentryi (Polygalaceae), a New Species of Liana from Central America and Colombia

The new species Moutabea gentryi, known from Costa Rica, Panama, and northwestern Colombia, is the northernmost member of its genus and the only species of Moutabea known from Central America. It is related to M. aculeata of the western Amazon basin but is distinguished by features of venation, leaf surface texturing, petiole color, and calyx pubescence. Study of the types of M. aculeata and M. longifolia indicates that the latter is a synonym of the former. Problematic populations and probably ndescribed taxa related to M. aculeata and M. gentryi exist in western South America.
