Abstract
A new species of Myrcia (Myrtaceae) from the Brazilian Atlantic Forest in the state of Rio de Janeiro is described and illustrated. The species is recognizable by its strongly bullate leaf blades, long, axillary and terminal, coppery and strigose inflorescences and calyces completely fused in the flower buds, tearing deeply vertically into 4–5 homogeneous sepals at anthesis. We herein provide a morphological description of the new species along with taxonomic notes, preliminary conservation status, illustrations, and a map of occurrence records.
