Abstract

Two new species of Melastomataceae are described and illustrated: Henriettea sierrae from the mountains of eastern Cuba, and Henriettea multigemma from the Sierra de Bahoruco in the Dominican Republic, Hispaniola. Both species belong to the complex of squamous Henriettea species endemic to the Greater Antilles. Henriettea sierrae is distinguished by its ciliate leaves, foliose bracteoles at the base of the flowers, and lanceolate petals with lateral teeth in their apical third. Henriettea multigemma is distinguished by its fascicles of numerous flowers that are borne of suberose protuberances formed by multiple flower buds in the leafless nodes of the stems, and by the presence of leaves with apical domatia.
