Abstract

Croton macrobothrys subsp. septentrionalis, a new subspecies of section Cyclostigma from the Brazilian Atlantic Forest, is here described and illustrated. It occurs in moist forests between 100–1000 m of elevation in the states of Bahia, Alagoas, and NE Minas Gerais. Given this new finding, we expand the morphological delineation of Croton macrobothrys and update its geographic distribution. We also provide a key to the two subspecies and identify the name C. macrobothrys var. microbothrys as a nomen nudum under Croton echioideus in section Adenophylli.
