Abstract
Exploratory field expeditions to the western slopes of the Ecuadorian Andes resulted in the discovery of a new species of Monopyle (Gesneriaceae). Monopyleglutinosa J.L.Clark & Keene, sp. nov. is described as a narrow endemic from lowland forests along the border of the Reserva Ecológica Los Illinizas in the Province of Cotopaxi. The new species is unique for the presence of glutinous or sticky trichomes on the calyx lobes and outer surface of the inferior ovary. Based on IUCN guidelines, a preliminary conservation status is assigned as Critically Endangered (CR).
