Description: Rhizomatous perennials. Culms glabrous, terete, transversely septate, longitudinally uni- or pluritubulose, hollow between septa.
Leaves basal, occasionally all reduced to sheaths; when present, blade terete, transversely septate, longitudinally uni- or pluritubulose.
Inflorescence head-like, compact, pseudolateral, with numerous pseudospikelets on a solid core; lowest involucral bract appearing continuous with culm, terete, much exceeding inflorescence. Each pseudospikelet composed of a few sterile glumes plus few–numerous glumes each subtending 1 stamen, plus 1 uppermost female flower. Glumes spirally arranged, thin-textured, white or pale brown at their base darkening towards their apex, becoming narrower and simpler in shape from base to apex of pseudospikelet. Style 2–4[or 5]-fid.
Nut woody, obovoid to globose, longitudinally ridged.
Distribution and occurrence: World: 6 species, Australia & New Caledonia. Australia: 5 species (4 species endemic), all States except N.T.
