Myrcia psammophila (Myrtaceae), a new species from the Amazonian white-sand vegetation

Abstract

The new species Myrcia psammophila is here described, illustrated and compared with M. grandis and M. umbraticola, two morphologically similar taxa. It may be distinguished from these two latter species based on possession of leaves with corky petiole and raised midvein adaxially, and distinctly pedicellate flowers with squared staminal ring and sepals united at the base. This species is endemic to a region of lower Rio Negro and inhabits areas of white-sand vegetation. Copyright © 2019 Magnolia Press
