Pentapogon avenoides, or mountain oat grass,[2] is a species of grass, endemic to New Zealand.[3] 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.[4] The seeds are wind-dispersed.[4] The habitat ranges from forest areas to scrub and tussock-land, from lowlands to uplands.[5]

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)[3]

The species was recently combined with Pentapogon based on genetic analysis of the entire genus.[6]
