Panicum hallii subsp. hallii

Treatment appears in FNA Volume 25. Treatment on page 467.

Plants often depauperate, occasionally large, sparsely to moderately pubescent or hirsute. Blades usually erect or ascending, tending to arise from basal clumps and curl at maturity. Panicles usually greatly exceeding the blades, with a few spikelets; main branches solitary, ascending, well-separated. Spikelets 3-4.2 mm.

Discussion

Panicum hallii subsp. hallii usually grows on drier sites than subsp. filipes. Its range extends from southern Colorado and Kansas to north central Mexico.
