TYPE-COLLECTION.—Yunque de Baracoa, Cuba, C. Wright 3081 (GOET, holotype; BM, G, GH (Figure 70a), K, isotypes).

DISTRIBUTION AND ECOLOGY.—Of all known species of Gesneria, G. reticulata is the most widespread with a center of distribution in the mountains of Hispaniola and outliers in the Oriente Province of Cuba and in the Luquillo Mountains of eastern Puerto Rico (Figures 54, 65, and 68). Its habitat is usually wet woods, near or at the edge of streams and waterfalls on igneous or limestone rocks from 80 to 1200 meters elevation. This species has been collected with flowers in all months except September. In cultivation, plants may flower continuously.
