Anastrophus platycaulis Nash, in Small, Fl. SE. U. S. 79. 1903. 
A tufted perennial with long creeping leafy stolons, flat and obtuse leaf-blades, and 
pubescent spikelets. Stems up to 1 m. tall, with one or more leafless branches above; leaf- 
sheaths much compressed, keeled, glabrous; blades glabrous or ciliate on the margins, the 
larger 3 dm. long or less, 3-15 mm. wide, linear to linear-lanceolate, those on the creeping 
stolons numerous, smaller and crowded; racemes in a pair at the summit of the stem, or 
sometimes with an additional one a short distance below, 3-10 cm. long; spikelets 2-2.25 mm. 
long, elliptic, oblong, or ovate, acute or obtuse, the outer 2 scales appressed-pubescent near 
the margin, 5-nerved, or sometimes 4-nerved by the suppression of the midnerve, the fruiting 
scale pubescent at the apex with a tuft of hairs.

A tufted perennial with long creeping leafy stolons, broad flat leaf-blades, and glabrous 
spikelets. Stems 3-10 dm. tall, with one or more leafless branches above; leaf-sheaths glabrous 
or hirsute, much compressed, keeled; blades glabrous or hirsute, 3 dm. long or less, 6-15 mm. 
wide, linear; racemes in pairs at the summit of the stem, rarely with an additional one a short 
distance below, 3-15 cm. long; spikelets 4-6 mm. long, glabrous, acute, the outer scales 5- 
nerved, or the second often 4-nerved by the suppression of the midnerve, the fruiting scale 
one half to two thirds as long as the others.
