(Hochst. & Steud.) Clayton
Treatment appears in FNA Volume 25. Treatment on page 511.

Plants annual. Culms 30-120 cm, erect or decumbent, sometimes rooting at the lower nodes; nodes and internodes glabrous. Sheaths smooth, glabrous; ligules 0.5-1 mm; blades 6-40 cm long, 3-8 mm wide, linear, flat to involute, glabrous adaxially. Panicles 6-18 cm long, 0.8-3 cm wide; rachises smooth or scabrous; branches 3-10, 25-60 mm long, 0.4-0.6 mm wide, sometimes winged, glabrous, with 20-40 spikelets, spikelets solitary or in unequally pedicellate pairs at the middle of the branches; pedicels 0.2-0.8 mm, glabrous or hairy below, apices with fewer than 10 hairs to 0.5 mm long. Spikelets 2.7-3.6 mm long, 0.8-1.5 mm wide, lanceolate. Upper glumes 1.1-1.3 times longer than the lower lemmas, hairy, 5-veined, apices acuminate and acute to awned, awns 0.3-1.5 mm; lower lemmas 2.5-3.3 mm long, 0.8-1 mm wide, setose, apices acuminate and mucronate; lower paleas absent; anthers absent; upper lemmas 1.7-2.2 mm, elliptic, acute to rounded, awned, awns 0.2-0.5 mm. 2n = unknown.

Discussion

Eriochloa fatmensis is native to tropical Africa, Arabia, and India, where it usually grows in wet areas or grasslands. It has been found in Tucson, Arizona, and Biloxi, Mississippi, but is probably not established in the Flora region.
