Regions

Los Lagos, Aysén del General Carlos Ibáñez del Campo, Magallanes y la Antártica Chilena and Archipiélago de Juan Fernández

Habitat

Temperate Forests, Valdivian rainforest, Juan Fernández rainforest, Patagonian Steppe and Andean Subpolar Forests and Wetlands

Distribution and habitat

Most populations occur in the archipelago of southernmost Chile but with locations in the Cordillera de Piuchén on Chiloé Island, and on Alexander Selkirk Island (Juan Fernández archipelago). It often forms small cushions or lax mats in open habitats such as mountain bogs, seepage areas, alpine moors and along streams. It has an altitudinal range from sea level in southern Chile to 1400 m on Alexander Selkirk Island (Moore,1983; Swenson, 1995).

This species has a markedly separated (disjunct) distribution, most notably with a population on Alexander Selkirk Island (Juan Fernández archipelago) some 1,155 km from the nearest population on the Island of Chiloé. This subantarctic element found on this Pacific island is the result of seed or possibly plantlets becoming attached to migratory birds (Stuessy, 2017).
