Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.
Christen Christensen Raunkiær was a Danish botanist, who was a pioneer of plant ecology. He is mainly remembered for his scheme of plant strategies to survive an unfavourable season and his demonstration that the relative abundance of strategies in floras largely corresponded to the Earth's climatic zones. This scheme, the Raunkiær system, is still widely used today and may be seen as a precursor of modern plant strategy schemes, e.g. J. Philip Grime's CSR system.
Tyge Wittrock Böcher was a Danish botanist, evolutionary biologist, plant ecologist and phytogeographer.
Botaniska Notiser was a Swedish scientific periodical concerning botany, issued in Lund, by Societate botanica Lundensi or [Lunds Botaniska Förening]. It was published from 1839 to 1980, when it fused with Botanisk Tidsskrift, Friesia and Norwegian Journal of Botany to form the Nordic Journal of Botany. In 2001, the journal reappeared as a regional journal for botany in south Sweden.
Olaf Hagerup was a Danish botanist. He studied botany at the University of Copenhagen from 1911 under the professors Eugenius Warming, Christen C. Raunkiær, L. Kolderup Rosenvinge og W. Johannsen. He took his Ph.D. from the same university in 1930. From 1934 to 1960, he was superintendent at the Botanical Museum of the University of Copenhagen.
Fredrik Christian Emil Børgesen was a Danish botanist and phycologist. He graduated in botany from the University of Copenhagen and was subsequently employed as an assistant at the Botanical Museum (1893–1900). His doctoral thesis dealt with the marine algae of the Faroe Islands (1904). Later, he became librarian at the Library of the Botanical Garden (1900–1935).
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.
Gunnar Seidenfaden was a Danish diplomat and botanist. He was Danish ambassador in Thailand 1955–1959, and in the U.S.S.R. 1959–1961. He was an expert on Southeast Asia Orchidaceae. He published several multi-volume works on orchids, e.g. The Orchids of Thailand – A Preliminary List and Orchid Genera in Thailand vol. I- XIV. These works are strictly taxonomic and floristic, but decorated with Seidenfaden's own drawings of flower parts as seen under the dissection microscope. His collection of more than 10,000 specimens was donated to the University of Copenhagen, together with original drawings by Katja Anker and others.
Gunnar Nygaard was a Danish phycologist, and a leading authority on the ecology and taxonomy of Danish phytoplankton. Nygaard completed his master's at University of Copenhagen, initially working at the Freshwater Biological Laboratory in Hillerød as a research stipendiary. From 1933 until his retirement in 1972 he was employed as a lecturer in the Danish grammar school system. Thereafter, he was provided an office at the Freshwater Biological Laboratory to facilitate his work. In recognition of his scientific contributions, the University of Copenhagen awarded him the degree dr. scient. honoris causa.
Bulbophyllum gyrochilum is a species of epiphytic orchid described by Gunnar Seidenfaden, in the genus Bulbophyllum.

Peristylus, sometimes commonly known as ogre orchids or bog orchids is a genus of flowering plants from the orchid family, Orchidaceae. It consists of over 100 known species found across much of eastern and southern Asia as well as in Australia and on many islands of the Indian and Pacific Oceans.
Seidenfadenia is a genus of flowering plants from the orchid family, Orchidaceae.
Leslie Andrew Garay, born Garay László András, was an American botanist. He was the curator of the Oakes Ames Orchid Herbarium at Harvard University, where he succeeded Charles Schweinfurth in 1958. In 1957 he was awarded a Guggenheim Fellowship.
Didymoplexiopsis is a genus of plants in the family Orchidaceae. The genus contains only one species, Didymoplexiopsis khiriwongensis, native to Hainan, Vietnam, Laos and Thailand.
Cleisostoma williamsoni is a species of orchid. It is found in Asia.
Bulbophyllum maxillare, commonly known as the red horntail orchid, is a species of epiphytic orchid with tapered grooved, dark green to yellowish pseudobulbs, each with a single large, thin leaf and a single reddish flower with yellow or white edges. The lateral sepals are much larger than the dorsal sepal which in turn is much larger than the petals. It grows on the lower branches of rainforest trees in India, New Guinea and tropical North Queensland.
Charles Samuel Pollock Parish (1822–1897) was an Anglo-Indian clergyman and botanist who served as chaplain to the forces of the Honourable East India Company in Burma. With his wife Eleanor he collected and painted plants, chiefly orchids, identifying and naming a number of species new to science. Several species are named in his honour.
