Abstract

Clusia hirsuta Hammel (Clusiaceae), a new species from the Pacific wet forest in Colombia and Ecuador, is described. Trichomes are reported here for the first time in the genus and described using micromorphological techniques. Morphological and molecular data are used to establish the phylogenetic position of this newly described taxon within the genus Clusia L.
