A new species from the Chocó Biogeographic Region in the northern Andes is discovered while unravelling the hypocyrtoid corolla complex in Drymonia (Gesneriaceae)

Recent field expeditions to the Andes and herbarium research resulted in the discovery of a new species of Drymonia (Gesneriaceae). Drymonia tomentosa J.L.Clark & Clavijo is described from the western Andean slopes of northern Ecuador and southern Colombia. The new species is differentiated from other congeners by the presence of a tomentose indumentum on the stems, stout shoots, broadly oblong leaves, and calyx lobes with broadly rounded apices. Based on IUCN guidelines, a preliminary conservation status is assigned as Least Concern (LC).
