Munro ex Morong & Britton
Common names: Intermediate paspalum
Introduced
Treatment appears in FNA Volume 25. Treatment on page 586.

Plants perennial; shortly rhizomatous. Culms to 200 cm, erect; nodes glabrous. Sheaths glabrous; ligules 2-3 mm; blades to 57 cm long, 2-3 cm wide, flat, glabrous below, appressed-pubescent above. Panicles terminal, with 60-100 racemosely arranged branches; branches 1-13 cm, divergent to spreading, often arcuate; branch axes 0.9-1.2 mm wide, winged, margins scabrous, long-pubescent. Spikelets 2-2.4 mm long, 0.9-1.2 mm wide, paired, divergent to spreading from the branch axes, elliptic to ovate, glabrous or pubescent, stramineous, sometimes partially purple. Lower glumes absent; upper glumes smooth, 3-veined, margins entire, sparsely short-pubescent, at least distally; lower lemmas smooth, lacking ribs over the veins, 3-veined, margins entire, glabrous or shortly pubescent; upper florets stramineous to white. Caryopses 1.5-1.7 mm, golden brown. 2n = 20, 40.
