Abstract

A new species of Anthurium section Pachyneurium, A. pedrovianae sp. nov. is described and occurs in canga vegetation of Serra dos Carajás, Pará State, Brazil. Information on conservation status, taxonomy, habitat, geographic distribution, and phenology is provided. Morphologically, the new species is similar to A.lindmanianum but differs from that species peduncle > 3 times the size of the petiole and a spadix < 6 cm long., stipe 6.0–11.0 cm long., purple at the base at the junction with the peduncle, berries are entirely purple, obovate, brown, warty seeds. Additionally, an identification key to distinguish the Pachyneurium species present in Pará is included.
