Description

Perennial with very short rhizome. Leaves flat, herbaceous, rather abruptly acuminate, with scabrous margins and scabrid nerves, grassgreen on both sides, 5-8 mm wide; Inflorescence compound to supradecompound, diffuse, lax, up to 40 cm across. Stamen 1;

Distribution

Andamans present, Asia-Tropical: Assam (Assam present), Banten present, Mt Halimun near Nirmala present, Tenasserim present, W. Java present

Obviously a very rare species, only known from the type collection (Tenasserim or Andamans), Assam, and Malesia: W. Java (Banten: Mt Halimun near Nirmala).

Notes

In sect. Diffusi the species stands rather apart by the numerous solitary spikelets, the nerveless grooved sides of the glumes, the single stamen (CLARKE, 1884, wrongly indicates stamens 2), and the small nut. There are strong affinities with sect. Halpani.
