Discussion
Panicum hirticaule subsp. hirticaule is the most commom of the subspecies, growing throughout the range of the species but occurring more often in arid habitats. It includes P. alatum Zuloaga and Morrone, a recently described species that differs from P. hirticaule subsp. hirticaule by the presence of paired elaiosomes at the base of a slightly stipitate upper floret.
