Common names: Wright's paspalum
Treatment appears in FNA Volume 25.

Plants perennial; aquatic to semiaquatic, conspicuously rhizomatous or stoloniferous. Culms 80-150 cm, erect; nodes glabrous. Sheaths glabrous or sparsely pubescent; ligules 1-3 mm; blades to 35 cm long, 2-7 mm wide, flat, glabrous above, pubescent below, especially basally. Panicles terminal, with 5-8 racemosely arranged branches; branches 3.5-11 cm, divergent to erect; branch axes 0.6-1.1 mm wide, glabrous, terminating in a spikelet. Spikelets 2.2-2.7 mm long, 1-1.4 mm wide, paired, appressed to or divergent from the branch axes, elliptic, glabrous, light-brown. Lower glumes absent; upper glumes glabrous, 3-veined; lower lemmas glabrous, 5-veined; upper florets glossy chestnut-brown. 2n = unknown.
