Drymonia atropururea (Gesneriaceae), a new species from northwestern South America

Recent expeditions to the western Andean slopes of Colombia and Ecuador and preliminary work on a revision of Drymonia (Gesneriaceae) have resulted in the discovery of a new species. The new species, Drymonia artropurpurea Clavijo & J.L. Clark, is distinguished from other congeners by large (up to 46 cm long) elliptic to oblong leaves, dark purple bullate calyces, and angulate (bent) corolla tubes.
