First record of Heterosperma for Brazil and an updated generic key for tribe Coreopsideae (Asteraceae)

Abstract We present the first record of Heterosperma (H. ovatifolium, Asteraceae) for Brazil as a result of the taxonomic study of tribe Coreopsideae for Northeastern Brazil. The genus currently comprises 11 species, occurring from southwestern United States to South America and the West Indies. We present a complete morphological description, a photo plate, and a distribution map with the updated distribution for H. ovatifolium. Additionally, we present an updated identification key for the genera of Coreopsideae for Brazil.
