    This was compared by Steyermark to Marlierea buxifolia. Because of its subcoriaceous leaves and white-tomentose inflorescence it bears a certain resemblance to Myrcia albido-tomentosa. Like that species its taxonomic position is somewhere between Marlierea and Myrcia. The margin of the hypanthium is thin and revolute but not split; the calyx-lobes are 4, glabrous, reflexed and often becoming partly detached at anthesis
