Arundinella nepalensis var. xerophila (Poaceae): A New Variety from Mustang, Nepal

摘要

A new variety of Arundinella nepalensis (Poaceae), var. xerophila, is described. This variety is different from var. nepalensis in leaf size, inflorescence length, callus hair length, spikelet and habitat. Arundinella nepalensis Trin. is alarge perennial grass and is widespread mainly in temperate regions of the Old World, from Southeast Asia to Africa (Keng 1959, Bor1960, Sun and Phillips 2006). During taxonomic work on grasses of Nepal, some specimens resembling A. nepalensis but unlike any described species of this area, were found. Further taxonomic work revealed that this plant differs from other known taxa, and is here described as a new variety of Arundinella nepalensis.
