ABSTRACT
A taxonomic study of the genera Henriettea and Henriettella in the flora of Rio de Janeiro State is presented. Each genera is represented by only one species - Henriettea saldanhaei and Henriettella glabra, that are found in the Atlantic forest. A key to identify the genera of the tribe Miconieae and the species studied is presented, as well as descriptions, illustrations, geographical distribution data and comments about nomenclatural and morphological particularities are provided. Three lectotypes are proposed and Henriettea glazioviana, H. glazioviana var. verruculosa and Henriettella glazioviana are accepted as synonyms. The occurrence of Henriettea saladanhaei and Henriettella glabra to the Espírito Santo State is pointed out for the first time.
