A new combination and new synonyms for Sauromatum Schott (Araceae—Areae) of northeastern India and Bangladesh

 

A. Hay & K.Z. Hein

 

ABSTRACT

Typhonium listeri Prain, of northeastern India and Bangladesh, is transferred into Sauromatum as S. listeri (Prain) K.Z.Hein & A.Hay, informed by an unpublished painting of the living plant made at Kolkata, India, at the time it was originally named. It is lecto- and epitypified. Its placement is discussed in the context of molecular understanding of generic relationships in the tribe Areae in which Sauromatum Schott is clearly distinct from Typhonium Schott despite their confused history. Sauromatum listeri is compared with the recently named Sauromatum meghalayense D.K.Roy, Talukdar, B.K.Sinha & Dutta Choud. and S. nangkarense Nangkar & Tag which are here placed in its synonymy. It is suggested that Sauromatum listeri may be most closely related to Sauromatum tentaculatum (Hett.) Cusimano & Hett. of Thailand. Some biographical notes on J.L. Lister, for whom the species was named, are given.
