Trichodrymonia isophylla (Gesneriaceae), a new species from the Colombian Andes

Recent field expeditions to the Andes and herbarium research have led to the discovery of a new species of Trichodrymonia (Gesneriaceae). Trichodrymonia isophylla J.L. Clark & Clavijo is widely distributed in the Cordilleras Central and Occidental in the Colombian Andes. This new species is distinguished from its congeners by isophyllous leaves that are evenly spaced on erect shoots, scale-like indumentum on stems and petioles, and a prominent submarginal collecting vein visible on both leaf surfaces. Following IUCN guidelines, a preliminary conservation assessment indicated that this species as Least Concern (LC).
