First record of Aristolochia wankeana (Aristolochiaceae, Piperales) from Brazil with a key to the species of Aristolochia subser. Anthocaulicae from the Brazilian Amazon

Abstract

ABSTRACT Aristolochia comprises about 450 species, occurring mainly in tropical regions. Here, we record for the first time Aristolochia wankeana in Brazil, specifically in two municipalities in the state of Amazonas (Presidente Figueiredo and Rio Preto da Eva). Previously, this species had only been recorded in Guyana and French Guiana. We provide the species description based on the new records, a preliminary extinction risk assessment, photographic plates, an updated geographic distribution map, ecological comments, and an updated key for species identification of Aristolochia subser. Anthocaulicae from the Brazilian Amazon.
