A new species of Cremosperma (Gesneriaceae) from northeastern Peru

Recent fieldwork and investigations of herbarium specimens during a preliminary revision of Cremosperma (Gesneriaceae) have resulted in the discovery of a new species. The new species, Cremosperma inversum B.R. Keener & J.L. Clark, is distinguished from other species in the genus by a suite of characters including orbicular leaves, stoloniferous habit, and tomentose-wooly indument on upper leaf surface. The distribution of trichomes on the adaxial leaf surface is clustered in the center of the bullae and away from the more or less glabrous veins and glabrous on the abaxial leaf surface away from the more densely pubescent veins. This species is endemic to sandstone outcrops in the Department of Amazonas in northwestern Peru
