Novae Gesneriaceae Neotropicarum IV: Alloplectus purpureus and Columnea nematoloba—New Gesneriaceae from northwestern South America

Abstract

Two species of Gesneriaceae are described:Alloplectus purpureus from the lower montane forests of northwestern Ecuador and adjacent Colombia andColumnea nematoloba from the lowland rain forests of western Colombia. The first with its fimbriate calyx lobes is probably nearest toAlloplectus sprucei, occurring in the same region but mostly at lower elevations. The second is in a group with two recently described species from western Ecuador and Colombia,Columnea fililoba andC. incredibilis, all having filiform corolla lobes.
