Abstract

Baccharis umbellata, a new species of Parana State, southern Brazil, is described. The new species, belonging to subgen. Baccharis sect. Agglomeratae, is easily recognized by the pedunculate heads arranged in an umbel-like capitulescence. Baccharis umbellata is a narrow endemic of the peaks of the southern range of Serra do Mar. It is morphologically most similar to the allopatric species B. platypoda, which mainly inhabits mountain summits in western and eastern South America. Illustrations, a distribution map, habitat information, and a conservation assessment are also provided for the new species. (AU)
