Croton suassunae (Euphorbiaceae): A New Dioecious Species from Northeastern Brazil
Abstract—
During a taxonomic revision of Croton sect. Lasiogyne in Brazil, a new species was found that is described and illustrated here. Croton suassunae clearly belongs to C. sect. Lasiogyne and is morphologically similar to C. tricolor and C. limae. Its distribution, habitat, phenology, and informal conservation status are presented, as well as an identification key and a table describing the differences between that species and its closest relatives. The discovery of C. suassunae adds dioecious plants and bifid styles to the concept of C. sect. Lasiogyne.
