Asarum rosei (Aristolochiaceae), a new species from the Blue Ridge Escarpment of North Carolina, USA

BRANDON T. SINN

Abstract


Hundreds of years of botanical exploration in heavily populated and highly accessible eastern North America have not exhausted taxonomic prospects in the region. Here, I describe a new species of Asarum (Aristolochiaceae), Asarum rosei B.T.Sinn, from North Carolina, USA. This species is characterized and contrasted with species in Asarum subgenus Heterotropa section Hexastylis, and a revised artificial taxonomic key to the similar species in the section is provided.
