Pentapogon avenoides, or mountain oat grass, is a species of grass, endemic to New Zealand. It is found on the main islands, as well as the Chatham Islands. The specific epithet, like the English name, refers to the oat-like structure of the inflorescence. The seeds are wind-dispersed. The habitat ranges from forest areas to scrub and tussock-land, from lowlands to uplands.
Synonyms Known synonyms include:
Agrostis avenoides Hook.f. in Handb. N. Zeal. Fl. 1: 330 (1864) Calamagrostis avenoides (Hook.f.) Cockayne in Rep. Bot. Surv. Tongariro Natl. Park: 35 (1908) Deyeuxia avenoides (Hook.f.) Buchanan in Indig. Grass. N. Zeal.: vi (1880)
The species was recently combined with Pentapogon based on genetic analysis of the entire genus.
