The history of the genus Sanango and its classification are reviewed. A detailed description is given of its gross morphology, trichome and seed surface micromorphology. Data on germination, phenology and distribution in Ecuador and Peru are presented. The author concludes that characteristics of the inflorescence, trichomes, fruit morphology and seed surface anatomy as well as seed development are consistent with the inclusion of Sanango in the Gesneriaceae.
