Description:  "Tufted perennial [grass] up to 120-150 cm tall; culms stout, erect, glabrous, somewhat bulbous at base, sheaths 7-14 cm long, glabrous or with sparse hairs at the collar, compressed, basal ones often purplish; ligule very short, but with a dense row of hairs just behind it; blades flat, 12-40 cm long, 3-12 mm wide, acute, scabrous, glaucous on upper surface; inflorescence of 4-6 racemes, these 2-4 cm long, alternate, distant, their axis 4-9 cm long, villous at base, sometimes pilose in the axils; rachis 1-1.5 mm wide, scabrous, usually reddish on the margins; spikelets paired, 2-2.5 mm long, broadly elliptic, imbricate, glabrous; second glume and sterile lemma 3-nerved; fertile lemma indurated, finely pitted; caryopsis 1.5 mm long, compressed-elliptic, pale"  (Stone, 1970; p. 218).

"The character used to distinguish Paspalum orbiculare and P. scrobiculatum, the presence of single or paired spikelets in the raceme, is a weak one.  Other differences in spikelet shape and coloration are equally unreliable in providing a basis for maintaining these as separate species"  (Wagner et al., 1999; pp. 1576-1577).

Description from GrassBase.

Habitat/ecology:  "In Fiji, abundant at elevations up to 1,300 m in clearings, along roadsides, in pastures, ditches, waste land, etc." (Smith, 1979; pp. 338-339).  In Hawai‘i, "common on slopes in poor, thin soil where few other grasses will grow, and in wet, swampy ground, 0-1,070 m (Wagner et al., 1999; pp. 1576-1577). In New Caledonia, "spontané mais peu commun en formations secondaires" (MacKee, 1994; p. 61).
