(Scribn.) Freckmann & Lelong
Synonyms: Panicum filipes
Treatment appears in FNA Volume 25. Treatment on page 467.

Plants often taller than subsp. hallii, sparsely pubescent to almost glabrous. Blades relatively lax, ascending to spreading, not strongly clustered basally or curling at maturity. Panicles scarcely exceeding the blades, with more closely spaced spikelets than in subsp. hallii; main branches rarely whorled, more crowded. Spikelets 2.1-3 mm.

Discussion

Panicum hallii subsp. filipes often grows in moist soil. Its range extends from Arizona, Texas, and Louisiana to southern Mexico.
