Poa pratensis, commonly known as Kentucky bluegrass, smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco. Although the species is spread over all of the cool, humid parts of the United States, it is not native to North America. The Spanish Empire brought the seeds of Kentucky bluegrass to the New World in mixtures with other grasses. Poa pratensis forms a valuable pasture plant, characteristic of well-drained, fertile soil. It is also used for making lawns in parks and gardens and is common in cool moist climates like the Pacific Northwest, and Northeastern United States. When found on native grasslands in Canada, however, it is considered an unwelcome exotic plant, and is indicative of a disturbed and degraded landscape.
Chamaenerion angustifolium is a perennial herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb, and traditionally known as Saint Anthony's Laurel amongst other variants. It is also known by the synonyms Chamerion angustifolium and Epilobium angustifolium. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests.
Epilobium is a genus of flowering plants in the family Onagraceae, containing about 197 species. The genus has a worldwide distribution. It is most prevalent in the subarctic, temperate and subantarctic regions, whereas in the subtropics and tropics Epilobium species are restricted to the cool montane biomes, such as the New Guinea Highlands.
The field vole or short-tailed vole is a grey-brown vole, around 10 cm in length, with a short tail. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal. These voles are found in moist grassy habitats, such as woodland, marsh or on river banks. Although they make shallow burrows, they usually build nests above ground. They are an important food source for owls and some other predators and their population size tends to peak and trough cyclically. Field voles breed prolifically, mainly in summer, but often all year round, even under snow. Females produce up to seven litters a year, each averaging from four to six young which are weaned after about fourteen days. The field vole is both widespread and common and is listed as being of "Least Concern" by the IUCN.
Calyptosuchus is an extinct genus of aetosaur from the Late Triassic of North America. Like other aetosaurs, it was heavily armored and had a pig-like snout used to uproot plants.
Epilobium hirsutum is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie.
Epilobium ciliatum, known by the common names fringed willowherb, American willowherb, slender willow herb, and northern willow herb is a species of flowering plant in the willowherb family Onagraceae. This species is native to much of North America, southern South America, and East Asia. It is an introduced species in much of Eurasia and Australia.
Epilobium densiflorum is a species of willowherb known by the common names denseflower willowherb, dense spike-primrose or dense boisduvalia. It is native to western North America from British Columbia to Baja California, where it is found in a variety of habitats. This is an erect annual often exceeding a meter in height with fuzzy green foliage. The pointed leaves are up to 8 centimeters long near the base of the plant, and the upper leaves are generally more hairy than the lower. The stem may branch or not. The top of the stem is occupied by a hairy, leafy, densely flowered inflorescence. Each flower has four deeply notched petals in shades of pinkish purple to nearly white with dark veining, each about a centimeter long. The fruit is a cylindrical capsule about a centimeter long.
Epilobium minutum is a species of willowherb known by the common names little willowherb, chaparral willowherb and desert willowherb. It is also called "smallflower willowherb" in reference to its small size relatively. However that name, in particular the British English variant "small-flowered willowherb", typically refers to Epilobium parviflorum.
Epilobium pygmaeum is a species of willowherb known by the common names pygmy willowherb, smooth spike-primrose and smooth boisduvalia. This plant is native to western North America from Baja California to Saskatchewan. It is a resident of vernal pools and mudflats. This is an annual rarely reaching half a meter in height. It is densely foliated in thick green leaves which are hairless lower on the stems and velvety to hairy toward the tips of the branches. The inflorescences at the ends of the stems are dense with small, pointed leaves between which the flowers emerge. Many of the flowers are cleistogamous, meaning they self-pollinate without opening, while others open to reveal four bright pink darkly veined notched petals. The fruit is a small capsule a few millimeters long.
Epilobium foliosum is a species of flowering plant in the evening primrose family known by the common names leafy willowherb and California willowherb. It is native to parts of western North America from British Columbia through California to Arizona, where it grows in many types of habitat, including disturbed areas.
Epilobium halleanum is a species of flowering plant in the evening primrose family known by the common name glandular willowherb. It is native to parts of western North America from British Columbia to New Mexico, where it grows in many types of habitat. It is an erect perennial herb growing up to about half a meter tall. The leaves are oval in shape low on the stem and narrower and somewhat lance-shaped higher, the longest about 4.5 centimeters long. The inflorescence is a raceme of glandular flowers, each with four notched white to pink petals a few millimeters long. The fruit is an elongated capsule up to 6 centimeters long.
Epilobium leptophyllum is a species of flowering plant in the evening primrose family known by the common names bog willowherb and linear-leaved willowherb. It is native to much of eastern and northern North America, where it grows in moist areas, such as bogs. It is a perennial herb growing up to a meter tall and spreading with tiny stolons. The leaves are generally linear in shape but may be wider to nearly oval, and reach up to about 7.5 centimeters. The inflorescence is a raceme of small flowers with white to pink petals a few millimeters long. The fruit is a hairy, elongated capsule up to 8 centimeters in length.
Epilobium torreyi is a species of flowering plant in the evening primrose family known by the common names Torrey's willowherb and brook spike-primrose. It is native to western North America from British Columbia to California, where it grows in many types of habitat, often in moist areas. It is a hairy annual herb producing a narrow, upright stem often exceeding half a meter tall lined with narrow lance-shaped leaves. The hairy, glandular inflorescence bears tiny white or pink flowers. They are usually cleistogamous, remaining closed and self-pollinating. The fruit is a capsule up to about a centimeter long.
British NVC community OV26 is one of the open habitat communities in the British National Vegetation Classification system. It is one of four tall-herb weed communities.

Hakea macraeana, commonly known as the willow needlewood or Macrae's hakea, is a species of shrub native to eastern Australia. The species was first formally described by botanist Ferdinand von Mueller in 1886 in the Australian Journal of Pharmacy. The species name honours one George Macrae, who aided the original collector William Baeuerlen.
