Flora of Svalbard

× Pucciphippsia is a nothogenus of Arctic plants in the grass family, reported from Greenland, Svalbard, and Magadan. The nothogenus is derived from a hybridization between Phippsia and Puccinellia. Species × Pucciphippsia czukczorum Tzvelev - Magadan Oblast (part of the Russian Federation) × Pucciphippsia vacillans (Th.Fr.) Tzvelev - Greenland (part of Denmark), Svalbard (part of Norway)

× Pucciphippsia vacillans is a member of the nothogenus × Pucciphippsia, formed by the hybridization of Phippsia and Puccinellia. It is a small, perennial grass, which is native to the arctic and grows well in wet conditions. × Pucciphippsia vacillans is entirely sterile, polyploid, and can only be formed as a product of hybridization. There has been difficulty in defining × Pucciphippsia vacillans parent species, and this may be representative broader difficulties in understanding species delineations and phylogenetics among arctic flora.

× Arctodupontia is a nothogenus of Arctic and Subarctic plants in the grass family. The only known nothospecies is × Arctodupontia scleroclada, found in the colder regions of Eurasia and North America (Nunavut, Svalbard, Magadan, northern European Russia). It is believed to have originated as a hybrid of two other arctic grasses: Arctophila fulva × Dupontia fisheri.

This species is native to Greenland, Kamchatka, Krasnoyarsk, Labrador, Magadan, North European Russia, Northwest Territories, Nunavut, Québec, Svalbard, Yakutskiya, and Yukon. It is perennial and mainly grows in subalpine or subarctic biomes. Festuca hyperborea was first described in 1957.

Goldilocks buttercup (Ranunculus auricomus agg.), sometimes also called Greenland buttercup, is a diverse group of species from the buttercup family (Ranunculaceae) native to Eurasia. It is an important model group in evolutionary biology, which is of great significance for research into the origins of apomixis, polyploidy, and speciation. Species are perennial and typically found in moist woods, at the margins of woods and waysides, and swamp meadows.

Draba corymbosa, also scientifically referred to as Draba corymbosa R. Br. ex DC., and commonly know as Flat-top Whitlowgrass and Drave en corymbe (FR) is a species of flowering plant native to Subarctic belonging to the family Brassicaceae.

Pleuropogon is a genus of Arctic and North American plants in the grass family known generally as semaphore grass. Pleuropogon native primarily to North America, with one species extending into Arctic Eurasia. These are erect grasses with drooping leaves. They grow in wet areas, sometimes even to the point of being partially submerged at times. Species Pleuropogon californicus (Nees) Benth. ex Vasey - annual semaphore grass - California (from San Luis Obispo Co to Humboldt Co) Pleuropogon davyi L.D.Benson - northwestern California Pleuropogon hooverianus (G.T.Benson) Howell - North Coast

Polemonium boreale, the northern Jacob's-ladder or boreal Jacobs-ladder, is a plant native to most of the high arctic. In Greenland it is found only in a small area on the east coast. It is not very common. The whole plant is pubescent, with long woolly hairs, glandular, and grows to 5–10 cm tall. The basal leaves are more or less alternate, and pinnate, with numerous leaflets. The flowers are produced in a more or less capitate inflorescence, each flower bell-shaped, blue, 15 mm long, 2.5 times longer than the calyx. The plant has a very unpleasant smell, and grows on gravelly slopes and in

The specific epithet vivipara is Latin, referring to the florets' alteration to leafy tufts. The plant can have a diploid number of 28, 49, 56, or 63, though numbers of 21, 35, and 42 have also been reported.
