Agrostis magellanica is a species of grass. It has a circumpolar distribution and is native to many subantarctic islands in, and the coasts bordering, the Southern Ocean. [1]
Agrostis magellanica is a tufted perennial grass, varying in height from 50 to 450 mm and forming short grassland communities. The culms have purple nodes. The leaves are wiry. The panicles are 20–120 mm long, with many shiny, greenish-purple, distinctly awned spikelets. [2]
The grass is found in the south-west of New Zealand’s South Island and on the Antipodes, Auckland, and Campbell Islands. It is also native to Macquarie Island and the Falkland, Kerguelen, Crozet and Prince Edward Islands, as well as southern South America in Tierra del Fuego. In New Zealand it occupies subalpine and alpine habitats on stony or rocky ground. In the subantarctic islands it grows at lower altitudes in peat and among mosses and cushion plants, or as scattered small plants in fellfield. [1] [2]
Rostkovia is a genus of flowering plants in the family Juncaceae. It was described in 1809.
Tussock grassland is a form of open grassland that is dominated by tussock grasses. It is common in some temperate grasslands, savannas, and shrublands ecoregions of the Southern Hemisphere. Tussock grasslands are usually typified by low rainfall and poor soils in which few plants other than hardy tussock grasses can flourish. They are predominantly populated by tufted grasses of the genera Agrostis, Andropogon, Chionochloa, Deschampsia, Festuca, Koeleria, Pentameris and Poa. The grasslands are found in New Zealand, Australia, Argentina, temperate areas of southern and eastern Africa, and some subantarctic islands.

Juncus scheuchzerioides is a species of rush variously called short rush or greater rush. It has an Antarctic circumpolar distribution and is native to many subantarctic islands in, and on the regions bordering, the Southern Ocean.
Coprosma perpusilla, commonly known as creeping coprosma, is a species of flowering plant in the family Rubiaceae. It is found in Australia, New Zealand and on some subantarctic islands. The specific epithet comes from the Latin per (very) and pusillus, referring to the growth habit.

Megaherbs are a group of herbaceous wildflowers growing in the New Zealand subantarctic islands and on the other subantarctic islands. They are characterised by their great size, with huge leaves and very large and often unusually coloured flowers, which have evolved as an adaptation to the harsh weather conditions on the islands. They suffer from overgrazing due to introduced mammals.
