Discussion
Paspalum setaceum var. muhlenbergii is endemic to the Flora region, extending from southern Ontario to the Gulf coast of Texas and northern Florida. It grows in disturbed areas and on the margins of forests. It resembles var. supinum, differing in its erect habit and, usually, in its spikelet shape and presence of a midvein on the lower lemma.
