Information
A loosely caespitose or solitary growing perennial, sometimes stoloniferous. Culms 10–40 cm., erect or creeping at the base, glabrous, nodes dark and glabrous. Leaf sheaths hairy. Ligule up to 2 mm. long, blunt or truncate. Leaf laminae 3–7 × 0.2–0.4 mm., linear, flat, hairy on both surfaces, margins scabrous, crisped. Inflorescence composed of 3–14 racemes, 5–15 cm. long, few together or solitary along a short common axis. Rhachis triquetrous, unwinged, up to 0.3 mm. broad, smooth with scabrous margins. Pedicels 2-nate, 0.3–2.5 mm. long, triangular to compressed, scabrous, somewhat broadened at the apex. Spikelets 2.7–3.5 mm. long, lanceolate, acuminate. Inferior glume at the base of the callus, remote from the superior glume, short, truncate, nerveless, hyaline. Superior glume as long as the spikelet, much longer than the superior lemma, lanceolate, acuminate, 7-nerved, pale green, appressed hair), hairs fine, slightly undulating with an irregularly recurved or circinate apex. Inferior lemma somewhat shorter than the spikelet, lanceolate, acuminate, 7-nerved, pale green, appressed hairy. Superior lemma much shorter than the spikelet, lanceolate, acuminate, yellow green to bluish green.
Habitat
River banks, dambos, roadsides and damp places in general.
