Anthurium viridivinosum sp. nov. (Araceae; A. sect. Urospadix subsect. Flavescentiviridia ) from a sedimentary coastal plain in southeastern Brazil

During a floristic survey of the family Araceae in a sedimentary coastal plain in the state of Espírito Santo, southeastern Brazil, we found an unknown species with an intriguing combination of characteristics intermediate among Anthurium harrisii , A. intermedium , A. jilekii, A. riodocense and A. zeneidae . Herein, we describe and illustrate this novelty as Anthurium viridivinosum with a comparative analysis of characters that distinguishes it from similar species, and comments about its ecology, distribution and conservation.
