Abstract

Two species characterized by locellate anthers are treated, belonging to different sections of Clusia. One of these species, Clusia favus, is described as new. A new name for a species with an unusual volcano-shaped male androecium, belonging to Clusia section Phloianthera, but originally described within the genus Arrudea, is also proposed. A very similar volcano-shaped androecium occurs also in some species of Clusia sect. Cordylandra.

É também proposto um nome novo para uma espécie com androceu de forma semelhante a um vulcão, pertencente a Clusia seção Phloianthera, mas originalmente descrita dentro do gênero Arrudea. Um androceu morfologicamente semelhante ocorre também em algumas espécies de Clusia sect. Cordylandra.
