Abstract

Ongoing research on the systematics of Drymonia (Gesneriaceae) resulted in the discovery of a new species, Drymonia mexicana Clavijo & J.L. Clark of the Gesneriaceae (tribe: Gesnerieae, subtribe: Columneinae). The new species is distinguished by the combination of narrow leaves with large corollas, glabrous leaves adaxially, calyx lobes ovate, and campanulate flowers with the tube slightly recurved ventrally and the limb purple. The new species is endemic to high elevation forests in the the Mexican state of Veracruz. The plant is commonly cultivated, but its introduction from Mexico to the horticultural community is unknown. Here, we describe and illustrate Drymonia mexicana Clavijo & J.L. Clark and present a key to identify the species of Drymonia native to Mexico.
