Poa kerguelensis is a species of tussock grass native to various subantarctic islands. The specific epithet refers to the type locality – the Kerguelen Islands.^[1]

Description

Poa kerguelensis is a perennial grass growing as hummocks up to 80 mm high and 150 mm in diameter.^[1]

The grass is found on the Heard, McDonald and Kerguelen Islands of the southern Indian Ocean. It grows on bare soil and in rocky areas where its hummocks trap wind-blown sand. On Heard Island it hybridises with Poa cookii ^[1] It is a pioneer coloniser of recently deglaciated areas.^[2]
