Ulmus glabra, the wych elm or Scots elm, has the widest range of the European elm species, from Ireland eastwards to the Ural Mountains, and from the Arctic Circle south to the mountains of the Peloponnese and Sicily, where the species reaches its southern limit in Europe; it is also native to the Caucasus region and parts of Western Asia (Turkey, Syria and Iran). A large deciduous tree, it is essentially a montane species, growing at altitudes up to 1,500 m (5,000 ft), preferring sites with moist soils and high humidity. The tree can form pure forests in Scandinavia and occurs as far north

Ficaria verna (formerly Ranunculus ficaria L.), commonly known as lesser celandine or pilewort, is a low-growing, hairless perennial flowering plant in the buttercup family Ranunculaceae. It has fleshy dark green, heart-shaped leaves and distinctive flowers with bright yellow, glossy petals. Native to Europe and Western Asia, it is now introduced in North America, where it is known by the common name fig buttercup and considered an invasive species. The plant is poisonous if ingested raw and potentially fatal to grazing animals and livestock, such as horses, cattle, and sheep. For these

Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the genus Ophrys, in the family of Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, a highly selective and highly evolved plant–pollinator relationship.

Drosera anglica, commonly known as the English sundew or great sundew, is a carnivorous flowering plant species belonging to the sundew family Droseraceae. It is a temperate species with a circumboreal range, although it does occur as far south as Japan, southern Europe, and the island of Kauai in Hawaii, where it grows as a tropical sundew. It is thought to originate from an amphidiploid hybrid of D. rotundifolia and D. linearis, meaning that a sterile hybrid between these two species doubled its chromosomes to produce fertile progeny which stabilized into the current D. anglica.

Orchis purpurea, the lady orchid, is a herbaceous plant belonging to the genus Orchis of the family Orchidaceae.

Rumex hydrolapathum, the great water dock, water dock, or giant water dock, is a species of perennial herbaceous plants in the genus Rumex native to fens and freshwater banks of Europe and Western Asia. It is the tallest species in the genus, with flowering stems attaining a height of up to 2 m (6 ft 7 in). It is one of the small number of decaploid organisms, containing two hundred individual chromosomes.

Carex sylvatica is a species of sedge found in deciduous woodlands across Europe. It typically reaches 60 cm (24 in) tall, and has an inflorescence made up of 3–5 pendent female spikes and a single male spike. It is also used as a garden plant, and has been introduced to North America and New Zealand.

Carex pendula (pendulous sedge, also known as hanging, drooping or weeping sedge) is a large sedge of the genus Carex. It occurs in woodland, scrubland, hedges and beside streams, preferring damp, heavy clay soils. It is sometimes grown as a garden plant because of its distinctive appearance. It is native to western, central and southern parts of Europe occurring north to Sweden, Denmark and parts of Scotland where it reaches 58° N. It is also found in north-west Africa, the Azores, Madeira and parts of the Middle East.

Narthecium ossifragum, commonly known as bog asphodel, Lancashire asphodel or bastard asphodel, is a species of flowering plant in the family Nartheciaceae. It is native to Western Europe, found on wet, boggy moorlands up to about 1,000 m (3,300 ft) in elevation. It produces spikes of bright yellow flowers in summer. The bright orange fruits have been used as a colourant to replace saffron by Shetland Islanders. Despite the plant's English name "bog asphodel", it is not particularly closely related to the true asphodels. In addition to other forms of pollination, this plant is adapted to

Alopecurus myosuroides is an annual grass, native to Eurasia, found in moist meadows, deciduous forests, and on cultivated and waste land. It is also known as slender meadow foxtail, black-grass, twitch grass, and black twitch.

Rosa arvensis, the field rose, is a species of wild rose native to Western, Central and Southern Europe.

Carex spicata is a species of sedge in the genus Carex.

Carex disticha is a Eurasian species of sedge known as the brown sedge or, in North America, tworank sedge.

Blackstonia perfoliata or more commonly known as the yellow-wort is a species of flowering plant in the family Gentianaceae found around the Mediterranean Basin, but extending into northwestern Europe.

Asplenium viride is a species of fern known as the green spleenwort because of its green stipes and rachides. This feature easily distinguishes it from the very similar-looking maidenhair spleenwort, Asplenium trichomanes.

Viola lutea, the mountain pansy, is a species of flowering plant in the Viola genus of the viola family, Violaceae. This evergreen perennial grows in Europe, from the British Isles to the Balkans.

Pimpinella major, common name greater burnet-saxifrage or hollowstem burnet saxifrage, is a herbaceous perennial plant in the genus Pimpinella belonging to the carrot family (Apiaceae).

Bromus erectus, commonly known as erect brome, upright brome or meadow brome, is a dense, course, tufted perennial grass. It can grow to 120 centimetres (47 in). Like many brome grasses the plant is hairy. The specific epithet erectus is Latin, meaning "erect". The diploid number of the grass is 56.

Narthecium is a Eurasian and North American genus of herbaceous flowering plants. This genus was traditionally treated as belonging to the family Liliaceae, but the APG II system of 2003 placed it in the family Nartheciaceae. The global distribution of the genus is widely disjunct, with species in Europe, Southwest Asia, Japan, the East Coast of the United States, and the West Coast of the United States. Narthecium americanum was a candidate for listing under the federal Endangered Species Act in the United States. Species Narthecium americanum Ker Gawl. – Eastern United States (†North and

Trifolium ochroleucon, also known as Trifolium ochroleucum or sulphur clover, is a perennial species of clover in the family Fabaceae.

Tofieldia is a small genus of flowering plants described as a genus in 1778. It is widespread across much of Europe, Asia, and North America. Tofieldia was once placed in the lily family, but is now generally included in the newer family Tofieldiaceae. The genus sometimes includes species of genus Triantha. Tofieldia are rhizomatous perennial herbs with spikes or racemes of lily-like flowers. The name Tofieldia commemorates the British botanist Thomas Tofield.

It is an annual, producing copious seed when habitat conditions are right, but not persisting in competition with other species. Although it is a relative of an important crop
