Naturalised. 1 species, from the Mediterranean. WA, SA, Qld, NSW, Vic, and Tas. Also Malesia and New Zealand.

Habit. Slender annual, tufted. Leaf blades narrow. Ligule an unfringed membrane or a fringed membrane (rarely).

Inflorescence. Inflorescence paniculate, a spike-like panicle, contracted.

Spikelets. Spikelets laterally compressed, 1 flowered, with 1 fertile floret, awned, solitary, pedicelled; with naked rachilla extension. Fertile spikelets disarticulating above glumes.

Glumes. Glumes more or less equal, long relative to adjacent lemmas, hairy (villous), pointed, awned, non-keeled, similar (narrowly lanceolate, membranous, hairy, tapering into fine bristles, thinly membranous). Lower glume 1 nerved. Upper glume 1 nerved.

Florets. Fertile florets 1. Lemmas similar in texture to glumes to decidedly firmer than glumes (membranous), not becoming indurated, incised, awned, 5 nerved, hairy or glabrous. Awns 3, the median different in form from laterals, dorsal, geniculate, hairless, much longer than body of lemma. Lateral awns shorter than median (terminal, straight).
