See text. Plants are living Organisms belonging to the kingdom Plantae. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Liliopsida is a Botanical name for the class containing the family Liliaceae (or Lily Family Asparagales is an order of Flowering plants The order must include the family Asparagaceae, but other families included in the order have varied markedly The Epidendroideae, or epidendroid Orchids are a Subfamily of the orchid family ( Orchidaceae) John Lindley ( February 8, 1799 - November 1, 1865) was an English Botanist. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

Coelogyne Lindl. 1821, is a genus of over 200 sympodial epiphytes from the family Orchidaceae, distributed across India, China, Indonesia and the Fiji islands, with the main centers in Borneo, Sumatra and the Himalayas. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic Orchids with sympodial growth have a specialized lateral growth pattern in which the terminal Bud dies An epiphyte is an organism that grows upon or attaches to a living plant India, officially the Republic of India (भारत गणराज्य inc-Latn Bhārat Gaṇarājya; see also other Indian languages) is a country China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National The Republic of Indonesia ( (Republik Indonesia is a Country in Southeast Asia. Fiji (Matanitu ko Viti फ़िजी officially the Republic of the Fiji Islands (Matanitu Tu-Vaka-i-koya ko Viti फ़िजी द्वीप समूह गणराज्य They can be found from tropical lowland forests to montane rainforests. A few species grow as terrestrials or even as lithophytes in open, humid habitats. The genera Bolborchis Lindl., Hologyne Pfitzer and Ptychogyne Pfitzer are generally included here. John Lindley ( February 8, 1799 - November 1, 1865) was an English Botanist. The genus is abbreviated Coel in trade journals.

The wide distribution of this genus has resulted in a wide variety of temperature variation from species to species, some requiring cool to cold conditions to grow and bloom reliably, while others need decidedly warmer temperatures to achieve the same. In Biology, a species is one of the basic units of Biological classification and a Taxonomic rank.

The scientific name is derived from the Greek words koilos (hollow) and gyne (woman), referring to the concave stigma. A gynoecium (from Ancient Greek gyne, "woman" is the Female reproductive part of a Flower.

This genus lacks the saccate base of the labellum, a typical characteristic which is present in the other genera in the subtribe Coelogyninae. The labellum (or Lip) is part of an Orchid, Canna or other less known flower that serves to attract Insects that Pollinate the flower The free lip has high lateral lobes along the basal part of the labellum (hypochile) and smooth, toothed or warty keels.

The pseudobulbs of one internode vary in size. The pseudobulb is a Storage organ derived from the part of a stem between two leaf nodes They may be closely or widely spaced through sympodial growth along the rhizome. Orchids with sympodial growth have a specialized lateral growth pattern in which the terminal Bud dies In Botany, a rhizome is a horizontal stem of a Plant that is usually found underground often sending out Roots and Shoots

Inflorescences often show a small to very large number of showy, medium-sized to large flowers. An inflorescence is a group or cluster of Flowers arranged on a stem that is composed of a main Branch or a complicated arrangement of branches A flower, also known as a bloom or Blossom, is the reproductive structure found in Flowering plants (plants of the division Magnoliophyta, also They may arise either from the apex of the newly completed pseudobulb at the end of the growing season (as in Coelogyne fimbriata), or may precede the new growth in early spring (as in Coelogyne cristata). The typical colour range of this genus is white, through tawny brown to green, and occasionally peachy tones. All species have four pollinia.

They have often a sweet scent, attracting different kinds of pollinators, such as bees, wasps and beetles. A pollinator is the biotic agent ( vector) that moves Pollen from the male Anthers of a Flower to the female stigma of a flower to accomplish

A few species are commonly known as 'necklace orchids', because of their long, pendant, multi-flowered inflorescence.

The cooler growing species such as Coelogyne fimbriata, Coelogyne ovalis, Colegyne fuliginosa, Coelogyne cristata, Coelogyne flaccida, Coelogyne nitida originate in the Himalayan region of India and southeast Asia. Coelogyne nitida is a species of Orchid in the Coelogyne Genus. They require a decided rest period during winter during which they receive no feed, very little water (enough to prevent pseudobulbs shrivelling), cool to cold temperatures and high light. These conditions seem to aid flowering in spring for some growers, though others report that more constant conditions can also produce regular flowering.

Coelogyne has never become very popular among orchid growers and has even been ignored. However there is now a growing number of man-made hybrids, such as :

The traditional taxonomy of the genus Coelogyne is still disputed. Taxonomy is the practice and science of classification The word comes from the Greek, taxis (meaning 'order' 'arrangement' and, nomos Coelogyne has been subdivided in 23 sections or subgenera by De Vogel (1994) and Clayton. Molecular data however show that Coelogyne is paraphyletic and should be reorganised, according to the study by Barbara Gravendeel et al. In Phylogenetics, a group of organisms is said to be paraphyletic if the group contains its most recent common ancestor but does not contain all given in the reference works here below :

This new genus Coelogyne should then contain about 160 species.
