Abstract

Here we describe a new species from the Brazilian Amazon, Mollia trimera. This species is mainly distinguished from other species of the genus by flowers with trimerous external whorls (calyx, corolla, and outer androecium), a rare morphological characteristic in Malvaceae. Morphological description, taxonomic comments, illustrations, distribution, habitat, preliminary conservation status, and phenology are provided.
