Diapensia is a genus of flowering plants of the family Diapensiaceae. Most of the species are found in the Himalayas. Diapensia lapponica has a high Arctic, circumpolar distribution.
The following species are recognised in the genus Diapensia: [2]
Saccharum is a genus of tall perennial plants of the broomsedge tribe within the grass family.
The bar-tailed godwit is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of Australia and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).
Linaceae is a family of flowering plants. The family is cosmopolitan, and includes about 250 species in 14 genera, classified into two subfamilies: the Linoideae and Hugonioideae. Leaves of the Linaceae are always simple; arrangement varies from alternate to opposite or whorled. The hermaphroditic, actinomorphic flowers are pentameric or, very rarely, tetrameric.
Epidendrum, abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family. With more than 1,500 species, some authors describe it as a mega-genus. The genus name refers to its epiphytic growth habit.
Syzygium is a genus of flowering plants that belongs to the myrtle family, Myrtaceae. The genus comprises about 1200 species, and has a native range that extends from Africa and Madagascar through southern Asia east through the Pacific. Its highest levels of diversity occur from Malaysia to northeastern Australia, where many species are very poorly known and many more have not been described taxonomically. One indication of this diversity is in leaf size, ranging from as little as a half inch to as great as 4 ft 11 inches by sixteen inches in Syzygium acre of New Caledonia.
Diapensia lapponica, the pincushion plant, is a plant in the family Diapensiaceae, the only circumboreal species in the genus Diapensia, the others being mainly in the Himalaya and on mountains in southwestern China. This species likely became circumboreal-circumpolar [Arctic–alpine] after it jumped to arctic habitat from North China and Russia. The most likely candidate for ancestor is a white-flowered D. purpurea The plants grow on exposed rocky ridges that are kept free from snow by high winds. Diapensia lapponica is extremely slow and low-growing and cannot compete with plants that overtop it. The plant is very sensitive to higher temperatures and so is often in misty foggy habitat. It usually dies when transplanted to lowland gardens and so this is not recommended. Cold-treated or wild and winter-collected seed will germinate indoors. The seed and leaves are high in lipids.

Diapensiaceae is a small family of flowering plants, which includes 15 species in 6 genera. The genera include Berneuxia Decne., Diapensia L., Galax Sims, Pyxidanthera Michx., Shortia Torr. & A.Gray, and Schizocodon Siebold & Zucc.. Members of this family have little economic importance; however, some members are cultivated by florists.
George Don was a Scottish botanist and plant collector.
Nomocharis is a genus of flowering plants in the family Liliaceae. It consists of about 7 species native to montane regions of western China, Myanmar, and northern India. They are similar to Lilium, with one of the more obvious differences being the flowers being more shallow or sometimes flat.
Erigeron acer is a widespread species of herbaceous flowering plant in the family Asteraceae. Common names include bitter fleabane and blue fleabane. The species is native to Canada, colder parts of the United States, northern, central, and southeastern Asia, and most of Europe.
Ixora is a genus of flowering plants in the family Rubiaceae. It is the only genus in the tribe Ixoreae. It consists of tropical evergreen trees and shrubs and holds around 544 species. Though native to the tropical and subtropical areas throughout the world, its centre of diversity is in Tropical Asia. Ixora also grows commonly in subtropical climates in the United States, such as Florida where it is commonly known as West Indian jasmine.
Rhodiola is a genus of perennial plants in the family Crassulaceae that resemble Sedum and other members of the family. Like sedums, Rhodiola species are often called stonecrops. Some authors merge Rhodiola into Sedum.
Acharia is a monotypic genus of flowering plants in the family Achariaceae. The sole species is Acharia tragodes, which is endemic to the Cape Provinces in South Africa.
Henning Eiler (Ejler) Petersen was a Danish mycologist, botanist and marine biologist. He made a major contribution to unveiling the mysterious die-back of eel grass in Northern European waters in the early 20th century as a pathogen outbreak.
The Structure and Biology of Arctic Flowering Plants is a classical scientific work on morphology and anatomy in relation to the harsh arctic environment. It was initiated by Eugenius Warming and conducted by himself and a suite of students and colleagues at the University of Copenhagen.
A pincushion is a small cushion used in sewing to store pins or needles.
The Paradisus Londonensis is a book dated 1805–1808, printed by D.N. Shury, and published by William Hooker. It consists of coloured illustrations of 117 plants drawn by William Hooker, with explanatory text by Richard Anthony Salisbury.
Anemonastrum is a genus of flowering plants in the family Ranunculaceae. Plants of the genus are native to the temperate and subarctic regions of North America, Greenland, Europe, Asia, South America, and New Zealand. The generic name Anemonastrum means "somewhat like anemone", a reference to the Anemone genus of closely related plants. It chiefly differs from Anemone in having a base chromosome number of x=7, as opposed to x=8.
Carex dioica, the dioecious sedge, is a species of flowering plant in the genus Carex, native to Iceland, the Faroes, Svalbard, nearly all of Europe, western Siberia, and the Altai. It prefers to live in calcareous fens.
