Distribution:  Central U.S. to Mesoamerica

Habitat:  Varied wet situations

Recognition:   Small, slender, grassy species with few flowers.

Leaves 0.5-1 mm wide; bristles ½ achene length.   Small plants with the 3-4.5 mm spikelets mostly single or in tiny clusters. Looks like miniature R. inundata.  Bristles with no plume, ½ the achene length, this strongly rugose. Could be confused with Fimbristylis autumnalis but the Fimbristylis with symmetrical cymose branching and longer spikelets (> 5 mm vs. < 4 mm)).

Florida status:  Native
