Descriptions
Chionochloa oreophila (Petrie) Zotov
Small, often mat-forming, pale tussock with persistent sheaths, and leaves very much shorter than slender flowering culms. Sheaths to 5 cm, pale, shiny, glabrous, chartaceous, persistent, margins undulating, tuft of hairs at apex to 3 mm. Ligule to 0.5 mm, sometimes to 1 mm. Lamina to 15 cm × 2 mm, U- or V-shaped, persistent, spiralling, pointed, narrower than sheath, keeled, veins few, abaxially with prickle teeth in upper V3, long internerve hairs frequent; adaxially with scattered prickle teeth; margins with prickle teeth below becoming glabrous above. Culms to 30 cm, internodes glabrous. Inflorescence to 6 cm, up to 8 spikelets on flexuous, pulvinate branches, glabrous except for few long hairs at branch axils and below spikelets. Spikelets small, solitary, of up to 6 purpled or golden florets. Glumes ± equal, to 10 mm, apex sometimes shortly awned, > adjacent lemma lobes; lower 3-5-nerved, upper 5-7-nerved, margin often long hairy below. Lemma to 4.5 mm; hairs long on margins, few aside central nerves and often few in all intemerves, < sinus; lateral lobes to 4.5 mm including awn to 2.5 mm, or shortly acute-triangular, central awn to 5.5 mm reflexed from flat 1.5 mm column. Palea to 5.5 mm. Callus to 1.5 mm, hairs to 2.5 mm. Rachilla to 0.75 mm. Lodicules to 0.6 mm. Anthers to 2.5 mm. Gynoecium: ovary to 0.7 mm, stigma-styles to 3 mm. Caryopsis to 2 mm.
