General Description
Warm season, dioecious, perennial sodgrass with creeping stolons. Stems 4–10 cm. leaf blades 1–1.5 mm wide, curly; sheaths with overlapping margins; ligule hairy. Inflorescence: staminate of 1 to 3 secund, lateral, divergent spikes, each 8–15 mm long with 10 to 15 spikelets, pistillate of 4 to 5 spikelets clustered into a short burr-like head or enclosed in sheathing leaf bases, this falling entire. Spikelets 4–6 mm long with 1 floret, the second glume becoming hardened and bony in texture and forming the burr-like covering. Lemmas distinctly 3-nerved, awnless, fused 2 to 5 together into a burr-like structure; palea enclosed in floret. Disarticulation above glumes in staminate inflorescence or below glumes in pistillate inflorescence; unit of dispersal is 3 to 5 spikelets enclosed in a burr-like covering (Lavin in Lesica 2012.
