Acaena magellanica, commonly called buzzy burr or greater burnet, is a species of flowering plant whose range includes the southern tip of South America and many subantarctic islands.
Acaena magellanica is a perennial, mat-forming plant with creeping stems, up to 14 cm (6 in) high. The leaves are oblong to linear-lanceolate, with 5 to 10 pairs of ovate leaflets. The flower heads are globular and grow on wiry stems well clear of the foliage. They are followed by brown, prickly seed heads; the seeds have small hooks which enables them to adhere to clothing, feathers or fur. [1]
The species is native to the southern part of South America. Its range includes Argentina, Chile and various sub-Antarctic islands including the Falkland Islands, the Kerguelen Islands, the Prince Edward Islands, Crozet Islands, South Georgia and the South Sandwich Islands and the Heard Island and McDonald Islands. Its typical habitat is damp places such as the edge of bogs, the banks of streams, waterlogged places, meadows and forest margins. It grows from sea level to an altitude of about 4,200 m (13,800 ft). [1]
In South Georgia, Acaena magellanica may cover the ground in dense patches. It is deciduous, and when the leaves are shed, mosses like Tortula robusta , which grows underneath, flourish. [2]
The Kerguelen Islands are in the Southern Indian Ocean Islands tundra ecoregion which is characterised by tussock grasses, lichens and liverworts. A. magellanica is one of the few low forbs that grew here, but the introduction of the European rabbit (Oryctolagus cuniculus), which selectively grazes the species it prefers, eliminated many of the native forbs. [3] When the rabbit was eradicated, A. magellanica and other forbs failed to recover because years of herbivory had depleted their seed banks, and introduced species such as annual meadow grass (Poa annua), mouse-ear chickweed (Cerastium fontanum) and dandelion (Taraxacum officinale) out-competed them. [3]
Herbaceous plants in botany, frequently shortened to herbs, are vascular plants that have no persistent woody stems above ground. Herb has other meanings in cooking, medicine, and other fields. Herbaceous plants are those plants that do not have woody stems, they include many perennials, and nearly all annuals and biennials, they include both forbs and graminoids.
Cordyline australis, commonly known as the cabbage tree, or cabbage-palm, is a widely branched monocot tree endemic to New Zealand.
Leucanthemum vulgare, commonly known as the ox-eye daisy, oxeye daisy, dog daisy and other common names, is a widespread flowering plant native to Europe and the temperate regions of Asia, and an introduced plant to North America, Australia and New Zealand.
Holcus lanatus is a perennial grass. The specific epithet lanatus is Latin for 'woolly' which describes the plant's hairy texture. Common names include Yorkshire fog, tufted grass, and meadow soft grass. In North America, where it is an invasive species, names include velvet grass and common velvet grass.
Alchemilla alpina, commonly known as alpine lady's-mantle, is an arctic-montane herbaceous perennial plant native to Europe and Southern Greenland.
Fuchsia magellanica, commonly known as the hummingbird fuchsia or hardy fuchsia, is a species of flowering plant in the family Evening Primrose family, native to the lower Southern Cone of southern South America.
Muehlenbeckia astonii or shrubby tororaro is an endemic New Zealand shrub in the family Polygonaceae. It has distinctive small heart-shaped deciduous leaves amidst a tangle of wiry interlocking branches. Although common in cultivation around the world, it is extremely rare and threatened in the wild.
The Kerguelen Islands are part of the Southern Indian Ocean Islands tundra ecoregion that includes several subantarctic islands. In this cold climate plant life is mainly limited to grasses, mosses and lichens, although the islands are also known for the indigenous edible Kerguelen cabbage. The islands are at the Antarctic convergence, where cold water moving up from the Antarctic mixes with the warmer water of the Indian Ocean. As a consequence, marine mammals, especially seals, and seabirds and penguins are numerous.
Dudleya traskiae is a rare succulent plant known by the common name Santa Barbara Island liveforever. This Dudleya is endemic to Santa Barbara Island, one of the Channel Islands of California, where it grows on rocky bluffs. The plant has a basal rosette of flat, spade-shaped fleshy leaves up to 15 centimeters long, which are pale green to yellowish. It erects tall stems bearing dense, rounded inflorescences of many bright yellow flowers.

Galeopsis bifida is an annual plant native to Europe and Asia but now found in Canada and the northeastern, midwestern parts of the United States. It has many common names such as bifid hemp-nettle, split-lip hemp-nettle, common hemp-nettle, and large-flowered hemp-nettle. The genus name means weasel-like, referring to the corolla of the flower. It is often confused with other species of Lamiaceae such as Mentha arvensis, Dracocephalum parviflorum and Stachys pilosa.
Gahnia grandis is a tussock-forming perennial plant found in southeastern mainland Australia and Tasmania.

Calochortus coxii is a rare species of flowering plant in the lily family known by the common names Cox's mariposa lily and crinite mariposa lily. It is endemic to Oregon in the United States, where it is known only from Douglas County.
Austroderia richardii, syn. Cortaderia richardii, is a species of flowering plant in the family Poaceae. It is an evergreen perennial grass. The genus Austroderia is often called "pampas grass", though this name usually refers to A. selloana. "Early pampas-grass" is a more specific name. The name "tussock grass" may also be found. The Maori name is "toetoe". It is one of five species in the genus Austroderia that are endemic to New Zealand. It occurs in the South Island and possibly also in the North Island. It is also an introduced species in Tasmania, Australia.
Acaena minor is a species of flowering plant whose range is confined to Australia's subantarctic Macquarie Island and to New Zealand's Campbell and Auckland Islands in the Southern Ocean.
Melampyrum arvense, commonly known as field cow-wheat, is an herbaceous flowering plant of the genus Melampyrum in the family Orobanchaceae. It is striking because of the conspicuous spike of pink or purple terminal bracts which includes the flowers.
