About

Colobanthus muscoides is a low-growing, moss-like flowering cushion plant in the family Caryophyllaceae, found on islands in the south-western Pacific Ocean, especially in the subantarctic region. The specific epithet comes from the Latin muscus (moss) and -oides (resembling), with reference to its growth habit.

Where it grows

The plant is found on New Zealand's Chatham, Snares, Antipodes, Auckland and Campbell Islands, as well as on Australia's Macquarie Island. It is common in coastal areas, where it forms extensive mats in bog communities and grows as cushions on peat, rock and sand in the sea spray zone.
