Phyllachne Colensoi (Berggren), an addition to the list of Sub-Antarctic plants in the Tasmanian flora

Certain Tasmanian plants of the Austral-Montane formation are characterised by a peculiar life-form and are described as 'cushion' or 'bolster' plants. These plants grow in dense tufts and make hard convex patches on the ground. Each may be several feet across, forming a compact mass that is firm underfoot. Phyllachne Colensoi (Berggren), belonging to the family Stylidiaceae, is a cushion plant similar in habit to four plants that are common on Tasmanian mountains.
