Flora of Marion-Prince Edward Islands

Elaphoglossum randii is a species of fern that grows only on the sub-Antarctic islands of Kerguelen and the Marion and Prince Edward Islands in the Indian Ocean.

Carex dikei is a sedge that is found on the Prince Edward Islands.

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.

Ranunculus biternatus, the Antarctic buttercup, is a plant in the buttercup family Ranunculaceae. It is native to southern South America (Chile and Argentina) and some subantarctic islands.

Carex austrocompacta, commonly known as compact hook sedge, is a sedge that is found in south eastern parts of Australia and on many sub-antarctic islands, including Crozet Island and Kerguelen Island.

Crassula moschata, commonly known as the Shore Stonecrop, Musky Stonecrop, or Musky Crassula, is a hairless, mat-forming, succulent, perennial herb. It is widespread on the subantarctic and cool temperate shores of the Southern Ocean.

Polypogon magellanicus (Syn. 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.

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.

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.

Austroblechnum penna-marina, synonym Blechnum penna-marina, known as Antarctic hard-fern, Little Hard Fern, Alpine Hard Fern, alpine water fern and pinque (Chilean Spanish), is a species of fern in the family Blechnaceae. It is a widely distributed fern species in the southern hemisphere, with a natural range including New Zealand, Australia, and South America. It has wiry rhizomes and exhibits strong dimorphism in its fronds. The sterile fronds are prostrate or semi-erect, growing up to 400 mm in length, while the fertile fronds are longer and held erect. The sterile fronds have a

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.

Hymenophyllum peltatum, also known as alpine filmy-fern, is a species of filmy fern widely distributed across Australia, New Zealand, South Africa, South America. It is predominantly a rainforest species with delicate foliage arrangements. Members of the Hymenophyllaceae family display almost translucent fronds, bearing thickness of just a single cell.

Limosella australis, common name Welsh mudwort, is an annual dicot plant that is indigenous to the United States and Canada. It has white flowers, and blooms between July and October. Its habitat is tidal mudflats, muddy or sandy shores It is listed as a special concern species in Connecticut.

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

Elaphoglossum is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

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

Grammitis (dwarf polypody) is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It had formerly been placed in the family Grammitidaceae, but this family is no longer recognized by most authors because phylogenetic analyses of DNA sequences have shown that it is embedded in Polypodiaceae. The delimitation of Grammitis was drastically narrowed in the first decade of the 21st century. It now contains about 25 species. In 2003, a study of the distribution of grammitid ferns placed 11 species in

Polypogon is a nearly cosmopolitan genus of plants in the grass family, commonly known beard grass or rabbitsfoot grass.

Hymenophyllum is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous leaf", referring to the very thin translucent tissue of the fronds, which gives rise to the common name filmy fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to desiccation. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.

Limosella is a genus of flowering plants known as mudworts. These are annual, largely aquatic plants, found in muddy areas worldwide. Its phylogeny and biogeography are inferred from molecular data.

Crassula is a genus of succulent plants containing about 200 accepted species, including the popular jade plant (Crassula ovata). They are members of the stonecrop family (Crassulaceae) and are native to many parts of the globe, but cultivated varieties originate almost exclusively from species from the Eastern Cape of South Africa. Crassulas are usually propagated by stem or leaf cuttings. Most cultivated forms will tolerate some small degree of frost, but extremes of cold or heat will cause them to lose foliage and die.

Blechnum, known as hard fern, is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Two very different circumscriptions of the genus are used by different authors. In the PPG I system, based on Gasper et al. (2016), Blechnum is one of 18 genera in the subfamily Blechnoideae, and has about 30 species. Other sources use a very broadly defined Blechnum s.l., including accepting only two other genera in the subfamily. The genus then has about 250 species. In the PPG I circumscription, the genus is

Potamogeton nodosus is a species of aquatic plant known by the common names longleaf pondweed and Loddon pondweed. It is native to Eurasia and the Americas, where it is widespread and can be found in water bodies such as ponds, lakes, ditches, and streams. This is a perennial herb producing a thin, branching stem easily exceeding a meter in maximum length. The submerged leaves are linear to widely lance-shaped and up to 15 by 4 centimetres (5.9 in × 1.6 in) in length and width, respectively, while the floating leaves achieve shorter maximum lengths and are ovate or elliptic. Both floating

Lycopodium (from Ancient Greek lykos, wolf and podion, diminutive of pous, foot) is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from nine to 15 species. In other classifications, the genus is equivalent to the whole of the subfamily, since it includes all of the other genera. More than 40 species are accepted.
