Dichanthelium multiglandulosum (Paniceae, Panicoideae, Poaceae) a new species from Jalisco, Mexico and the reestablishment of Panicum transiens as Dichanthelium transiens

Abstract

A new species, Dichanthelium multiglandulosum, from northwestern Jalisco, Mexico, is described and illustrated. Panicum transiens, an incorrectly synonymized name lost in history, is here proposed as D. transiens, with the rarely used name D. macrospermum treated as its synonym. Relationships of both species are discussed, and both are classified within Dichanthelium section Macrocarpa. A key and a table of differences and similarities among the new species and related species are provided.
