Genus Chionochloa Family Poaceae
Common Name: Snow grasses, wallaby grasses

Description: Tufted perennials, usually forming coarse tussocks.

Leaves with ligule a rim of hairs; blade folded or flat, often deeply grooved, margins scabrous.

Inflorescence an open panicle.

Spikelets flattened, disarticulating above the glumes, with 3–8 bisexual florets. Glumes 1–5-nerved, longer than the lemmas but shorter than the spikelet. Lemmas usually 7-nerved, distinctly 2-lobed with the lobes usually short-awned and longer than or equal to the lemma body; central awn a prolongation of the middle nerve, bent and twisted at the base, exceeding the lateral lobes; lemma back usually with scattered hairs 1–2 mm long; callus hairy. Palea hairy or glabrous; keels ciliate.

Distribution and occurrence: World: 21 species, Australia & New Zealand. Australia: 2 species (native), N.S.W., Vic.

These grasses mostly grow in alpine or upland areas and provide valuable summer grazing, catchment and slope protection, and animal shelter. Key based on Wheeler et al. (1990).
