| - 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. 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, Hologyne and Ptychogyne are generally included here. 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. The scientific name is derived from the Greek words koilos (hollow) and gyne, referring to the concave stigma. This genus lacks the saccate base of the labellum, a typical characteristic which is present in the other genera in the subtribe Coelogyninae. The free lip has high lateral lobes along the basal part of the labellum and smooth, toothed or warty keels. The pseudobulbs of one internode vary in size. They may be closely or widely spaced through sympodial growth along the rhizome. Inflorescences often show a small to very large number of showy, medium-sized to large flowers. They may arise either from the apex of the newly completed pseudobulb at the end of the growing season, or may precede the new growth in early spring . 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 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. They require a decided rest period during winter during which they receive no feed, very little water, 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 : Coelogyne 'Mem. W. Micholitz' Coelogyne 'Linda Buckley' Coelogyne 'Burfordiensis' . Coelogyne 'South Carolina', sometimes called "the black orchid" because of the black coloration of the heavily patterned and structured lip. The traditional taxonomy of the genus Coelogyne is still disputed. Coelogyne has been subdivided in 23 sections or subgenera by De Vogel and Clayton. Molecular data however show that Coelogyne is paraphyletic and should be reorganised, according to the study by Barbara Gravendeel et al. given in the reference works here below : Coelogyne should include the genera Neogyna and Pholidota the following sections should be removed from Coelogyne : sections Coelogyne (in part), Cyathogyne, Tomentosae, Rigidiformes, Veitchiae and Verrucosae. This new genus Coelogyne should then contain about 160 species. (en)
- Coelogyne est un genre de la famille des Orchidaceae, sous-famille des Epidendroideae, tribu des Coelogynae (Pfitzer), sous-tribu des Coelogyninae . Il comporte 190 espèces, 2 sous-espèces et 12 variétés, ce qui fait 204 taxons en tout. On trouve les Coelogyne sous tous les climats, chaud, tempéré, frais et froid, en Asie du sud et du sud-est jusqu'aux îles du Pacifique du sud-ouest à l'est. La plupart des espèces sont surtout épiphytes, bien que beaucoup soient lithophytes ou terrestres. Il est donc important de savoir d'où vient une plante. Les espèces chaudes comme pandurata, dayana ou speciosa ne demandent pas de repos alors que les espèces plus froides (C. cristata) demandent un repos hivernal au sec. Elles peuvent avoir des pseudo-bulbes serrés ou espacés le long du rhizome avec 1 ou 2 feuilles plicatives. L'inflorescence se fait soit à l'apex d'un pseudo-bulbe soit à l'apex d'une nouvelle pousse. (fr)
