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.
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.
Pleione is a small genus of predominantly terrestrial but sometimes epiphytic or lithophytic, miniature orchids. This genus is named after Pleione, mother of the Pleiades, and comprises about 20 species. Common names of this genus include peacock orchid, glory of the east, Himalayan crocus, Indian crocus and windowsill orchid. The genus DiploconchiumSchauer is generally included here. Pleione is abbreviated to Pln in trade journals.
Angraecum, also known as comet orchid, is a genus of the family Orchidaceae native to tropical and South Africa, as well as Sri Lanka. It contains 223 species.
Cypripedium is a genus of 58 species and nothospecies of hardy orchids; it is one of five genera that together compose the subfamily of lady's slipper orchids (Cypripedioideae). They are widespread across much of the Northern Hemisphere, including most of Europe and Africa (Algeria), Russia, China, Central Asia, Canada the United States, Mexico, and Central America. They are most commonly known as slipper orchids, lady's slipper orchids, or ladyslippers; other common names include moccasin flower, camel's foot, squirrel foot, steeple cap, Venus' shoes, and whippoorwill shoe. An abbreviation used in trade journals is "Cyp." The genus name is derived from Ancient Greek Κύπρις (Kúpris), an early reference in Greek myth to Aphrodite, and πέδιλον (pédilon), meaning "sandal".
Zygopetalum is a genus of the orchid family (Orchidaceae), consisting of fourteen currently recognized species.
Phalaenopsis, also known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.
Coelogyne 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 BolborchisLindl., HologynePfitzer and PtychogynePfitzer are generally included here. The genus is abbreviated Coel. in trade journals.
Bletilla, common name urn orchid, is a temperate, terrestrial genus of orchids containing five currently recognized species distributed through China, Japan, Taiwan, south to Vietnam, Thailand and Myanmar. The name is actually a diminutive of Bletia because of the resemblance between the two genera even though Bletia is a New World genus. The genera JimensiaRaf. and PolytomaLour. ex Gomes are generally included into Bletilla. This genus is abbreviated Ble in trade journals.
Kurseong is a town and a municipality in Darjeeling district in the Indian state of West Bengal. It is the headquarters of the Kurseong subdivision.
Phenanthrenoids are chemical compounds formed with a phenanthrene backbone. These compounds occur naturally in plants, although they can also be synthesized.
Rhynchostylis is a genus in the orchid family (Orchidaceae), closely allied to the genus Vanda and comprising four currently accepted species native to the Indian Subcontinent, China, Indochina, Malaysia, Indonesia and the Philippines. The name consists of a compound of two Greek elements : rhynchos 'beak' and stylis 'column' – in reference to the very broad, fleshy column of the flower. The flowers are borne in dense racemes and are noted for their intense, spicy fragrance. Although lacking in pseudobulbs, the plants have leathery leaves that are drought-resistant. These orchids grow naturally in warm, moist, shaded tropical areas and will thrive in cultivation if given consistent warmth, uniform moisture and bright, but indirect light. Hobbyists wanting to grow them will need a warm, humid growing environment with gentle air movement. They can be grown in pots, but are better grown in baskets, owing to the extreme fleshiness of their roots. Their unusually fragrant blooms often appear in the slightly cooler winter months.
Dendrobium nobile, commonly known as the noble dendrobium, is a member of the family Orchidaceae. It has become a popular cultivated decorative house plant, because it produces colourful blooms in winter and spring, at a time when little else is in flower. It is also one of the 50 fundamental herbs used in traditional Chinese medicine, known as shí hú or shí hú lán. Dendrobium nobile is one of the most widespread ornamental members of the orchid family. Its blooms are variegated in colour, shading from white through pink and purple, and the many different cultivated varieties produce different sized and coloured blooms.
Cattleya aclandiae, or Lady Ackland's cattleya, is a species of orchid from the genus Cattleya, named in honor of Lady Lydia Elizabeth Ackland, wife of Sir Thomas Dyke Acland, 10th Baronet who was the first European to grow the plant successfully. The illustration of the plant which accompanied its first description was based on a drawing by Lady Ackland. The genus was named in honour of William Cattley, a prominent British merchant and horticulturist.
Coelogyne flaccida is a species of orchid that is native to southeast Asia and northeastern South Asia. Cultivated as an ornamental plant, it is also known as the bearded coelogyne and the loose coelogyne.
Phalaenopsis gigantea is a species of orchid endemic to the island of Borneo and was first described in 1909. The specific epithet gigantea refers to the giant size of its leaves, which can grown over 60 cm in length on a mature plant. It is the largest known Phalaenopsis species.
Rodriguezia venusta is a species of orchid native to Guyana, Suriname, Venezuela, Ecuador, and Brazil.
Broughtonia sanguinea, also known as blood red broughtonia is a plant in the genus Broughtonia, a member of the family Orchidaceae. It was named in 1813 by its first describer, Robert Brown, for 18th century English botanist Arthur Broughton.
Coelogin is a phenanthrenoid found in the high altitude Himalayan orchid Coelogyne cristata. This molecule has a phenanthro[4,5-bcd]pyran structure.
Coeloginin is a phenanthrenoid found in the high altitude Himalayan orchid Coelogyne cristata. This molecule has a phenanthro[4,5-bcd]pyrone structure.
