Flora of Heard-McDonald Islands

Poa kerguelensis is a species of tussock grass native to various subantarctic islands. The specific epithet refers to the type locality – the Kerguelen Islands.

Ranunculus crassipes is a small flowering plant in the buttercup or crowfoot family Ranunculaceae that is native to the subantarctic region. The specific epithet comes from the Latin and refers to the plant's thicker and more succulent form compared to the closely related R. biternatus.

Pringlea antiscorbutica, commonly known as Kerguelen cabbage, is a flowering plant and the sole member of the monotypic genus Pringlea in the family Brassicaceae. Its common name comes from the archipelago of its discovery, the Kerguelen Islands, and its generic name derives from Sir John Pringle, president of the Royal Society at the time of its discovery by Captain James Cook's Surgeon, William Anderson in 1776. Despite its appearance and edibility, it is not related to the common broadleaf plantain.

Colobanthus kerguelensis is a low-growing, moss-like flowering cushion plant in the family Caryophyllaceae, found on subantarctic islands in the southern Indian Ocean. The specific epithet refers to the type locality – the Kerguelen Islands.

Poa cookii, sometimes called Cook's tussock-grass or bluegrass, is a species of tussock grass native to various subantarctic islands. The specific epithet honours British explorer James Cook who visited the Kerguelen Islands in 1776.

Leptinella plumosa is a small flowering plant in the daisy family. It is a circumantarctic species found on many subantarctic islands in the Southern Ocean. The specific epithet comes from the Latin for “feathery”, referring to the form of the leaves.

Azorella selago is a species of cushion plant native to the sub-Antarctic islands of the Southern Ocean, including the Crozet Islands, the Possession Islands, the Heard Island and McDonald Islands, the Kerguelen Islands, and the Prince Edward Islands. The closely related Azorella macquariensis, which is endemic to Macquarie Island, was split from it taxonomically in 1989. A. selago is often a keystone species where it occurs and is well studied for its contribution to its native ecosystems.

Deschampsia antarctica, the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being Colobanthus quitensis (Antarctic pearlwort).

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.

Callitriche antarctica, commonly known as the Antarctic water-starwort, is a small, prostrate plant with tiny yellow flowers in the family Plantaginaceae (though sometimes placed in its own family – Callitrichaceae). It is found in wet places on many subantarctic islands and has a wide circumantarctic distribution, something reflected in its specific epithet.

Leptinella is a genus of alpine flowering plant in the family Asteraceae, comprising 33 species, distributed in New Guinea, Australia, New Zealand, South Africa, and South America. Many of the species are endemic to New Zealand. For over 100 years, Leptinella species were considered part of the genus Cotula, but the genus Leptinella was reinstated by Lloyd & Webb in 1987. They determined that all species of Leptinella are distinguished from those of the other two sections of Cotula, and other Anthemideae, by the conspicuous "inflated" corollas of the female florets and by chromosome numbers

Azorella is a genus of flowering plants in the family Apiaceae, native to South America, New Zealand, southeastern Australia, and the islands of the Southern Ocean. They are low-growing dwarf mat-forming plants growing in high exposure on mountains and subantarctic coasts; with great age they may form rounded mounds of foliage up to 1 m high but are usually less than 10 cm high. Several species are grown as ornamental plants in rock gardens.

Colobanthus is a large genus of small, cushion-like herbaceous plants in the family Caryophyllaceae, sometimes known as "pearlworts", a name they share with plants of the related genus Sagina. C. quitensis is the world's southernmost dicot, and one of only two native extant flowering plants of Antarctica.

Acaena is a genus of about 60 species of mainly evergreen, creeping herbaceous perennial plants and subshrubs in the family Rosaceae, native mainly to the Southern Hemisphere, notably New Zealand, Australia and South America, but with a few species extending into the Northern Hemisphere, north to Hawaii (A. exigua) and California (A. pinnatifida). The leaves are alternate, 4–15 centimetres (1.6–5.9 in) long, and pinnate or nearly so, with 7–21 leaflets. The flowers are produced in a tight globose [inflorescence] 1–2 centimetres (0.39–0.79 in) in diameter, with no petals. The fruit is also a

Montia fontana, blinks is a herbaceous annual to perennial plant that grows in freshwater springs in upland regions, and in seasonally damp acid grassland in the lowlands. It is widespread throughout the world, except in southern Asia. It is rather variable in morphology, which is reflected in a complex history of taxonomy. Currently, there are three accepted subspecies which are defined largely by the appearance of the seedcoat. It is edible and consumed as a salad in some areas, but is otherwise of minimal economic impact. Because of its association with clean water habitats, it is often

Montia is a genus of plants in the family Montiaceae. Species in this genus are known generally as miner's lettuce or water chickweed. All of the species in the genus have edible leaves. It is found worldwide, except in Asia. Montias are known from fossilized seeds recovered from sediments of the Pleistocene Tomales Formation and from a small paleoflora at San Bruno. Further, Daniel Axelrod discussed Montia howellii as one of the biogeographically significant species comprising the Millerton paleoflora at Tomales. The genus name of Montia is in honour of Giuseppe Monti (1682–1760), an Italian

Deschampsia is a genus of plants in the grass family Poaceae, commonly known as hair grass or tussock grass. The genus is widespread across many countries. The genus is named for French physician and naturalist Louis Auguste Deschamps (1765–1842). Deschampsia species are used as food plants by the larvae of some species of Lepidoptera, including antler moth, the clay, clouded-bordered brindle, common wainscot, dark arches, dusky brocade, shoulder-striped wainscot, smoky wainscot and wall. Deschampsia sometimes grow in boggy acidic formations, an example of which is the Portlethen Moss,

Callitriche is a genus of largely aquatic plants known as water-starwort. Previously, it was the only genus in the family Callitrichaceae. However, according to the APG II system this family is now included in the Plantaginaceae (plantain family). The family name Callitrichaceae retains its status as nomen conservandum (name to be retained).

Poa is a genus of about 570 species of grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. Poa (πόα) is Greek for 'fodder'. Poa are members of the subfamily Pooideae of the family Poaceae. Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters). The genus Poa includes both annual and perennial species. Most

Ranunculus is a large genus of about 1750 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots. The genus is distributed worldwide, primarily in temperate and montane regions. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup Ranunculus repens, which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup Ranunculus bulbosus and the much taller meadow buttercup Ranunculus acris. In
