Key to Erianthus

A genus of XX species, perennials, of the New World. While Clayton & Renvoize (1986) stated that the “traditional division [of Saccharum] into awned (Erianthus) and awnless species seems wholly artificial”, Hodkinson et al. (2002) and others have developed molecular evidence which suggests that our species are not congeneric with Saccharum. It seems best to retain our species in Erianthus, following Soreng et al. (2015) and Lloyd Evans, Joshi, & Wang (2019).

ID notes:Awn twisting is judged from dry material, either herbarium specimens, mature (and dry) material in the field. With material that is not fully dry, a good life hack is to leave all or part of an inflorescence on the dashboard of a car to dry.
