Abstract
During the review of the Brazilian species of Lorostemon (Clusiaceae), we verified that some specimens previously reported as L. bombaciflorus Ducke for South Guyana and the Brazilian Eastern Amazonia belong to a species still unknown to science. Here, we provide a description, taxonomic comments, illustrations, and a distribution map of Lorostemon roseoviridis Fer.-Silva & L.Marinho, a new species from eastern Amazonia.

Etymology. The epithet refers to the predominant colors found in the flowers and derives from the Latin roseus (pink) and viridis (green). Ducke (1935) published the first species name in the genus as "L. bombaciflorum", indicating that Lorostemon would be neuter, but Art. 62.2 (a) of the ICN (Turland et al., 2018) states that compound generic names ending in -stemon are masculine.
