A new species of Drymonia (Gesneriaceae) from the eastern slopes of the Ecuadorian Andes


A new species, Drymonia ignea (Gesneriaceae, tribe Episcieae), is described from the eastern slopes of the Ecuadorian Andes from the provinces of Tungurahua, Napo, and Morona-Santiago. It differs from other species of Drymonia by the presence of an urceolate corolla, quadrangular stem, and cucullate calyx lobes.
