Eulophia, commonly known as corduroy orchids, [3] is a genus of about two hundred species of flowering plants in the orchid family, Orchidaceae. Most Eulophia orchids are terrestrial but some are deciduous while others are evergreen. They either have an underground rhizome or pseudobulbs on the surface and those species with leaves have them on the end of a fleshy stem. The flowers are arranged on a thin flowering spike, the flowers having sepals which are larger than the petals. The genus is widely distributed but most species are found in Africa and Asia, usually growing in shady places with grass or shrubs in forests.

Description

Orchids in the genus Eulophia are mostly terrestrial herbs with either an underground rhizome or pseudobulbs on the surface. The only two epiphytic species occur on Madagascar. Many species have no leaves, but when leaves are present they are long and narrow, sometimes pleated. The flowers are borne on a flowering stem which sometimes appears before the leaves with a few to many flowers. The flowers in some species are small but others have large, showy flowers in a wide range of colours. The sepals are usually larger than the petals but the labellum has three lobes and a spur or pouch at its base. [3] [4] [5] [6] [7]

Taxonomy and naming

The genus Eulophia was first formally described by John Lindley in 1821 and the description was published in The Botanical Register . Because Robert Brown had previously used the name Eulophia in describing Lissochilus speciosus, and the name of that species was changed to Eulophia speciosa , Brown is the accepted author of the name. "Eulophia" is derived from the Ancient Greek words eu meaning "good", "well" or "true" [8] :373 and lophos meaning "mane", "crest", "comb", "tuft" or "ridge", [8] :238 possibly referring to the labellum callus of some species. [6]

Distribution and habitat

Orchids in the genus Eulophia are distributed in shady rainforests or in open scrub or woodland in the tropics and subtropics of Africa, India, Asia, Queensland, and the Americas, although most are found in Africa. Many can survive the dry season through their large bulbous ‘corms’. Some species, such as Eulophia petersii , have adapted to very arid environments and are among the few orchids to have truly evolved desert living species.

Use in horticulture

In the frost-free, semi-arid areas of Southern California, many Eulophia species, such as E. macra , E. petersii , E. plantaginea , and E. speciosa , can be grown outdoors year-round in well-drained pots with cactus/succulent potting mix (although E. speciosa prefers being grown in pure white sand), as long as they are given ample light through the winter and a drier winter resting period. Warmer growers, such as E. pulchra and possibly even the extremely rare and difficult E. cucullata (the foxglove orchid), can probably be grown outdoors in the warmer south areas of Florida and Hawaii, also. The generally large, underground, fleshy rhizome indicates a sympodial growth habit, and this makes Eulophias fairly easy to divide and propagate, provided the grower is gentle.

<i>Bulbophyllum</i> Genus of orchids

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.

<i>Cypripedium</i> Genus of flowering plants in the orchid family Orchidaceae

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".

Oeceoclades decaryana is a terrestrial orchid species of the genus Oeceoclades that is native throughout southern and southeastern Africa.

It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1935 as a species in the genus Eulophia. He later transferred this species to the genus Lissochilus in 1941, followed by another transfer to the genus Eulophidium in 1957 by the English botanist V.S. Summerhayes in 1957. When Leslie Andrew Garay and Peter Taylor revised the genus Oeceoclades in 1976, they transferred this species to the expanded Oeceoclades.

Phalaenopsis tetraspis is a species of epiphytic orchid endemic to the Andaman Islands, the Nicobar Islands and northwestern Sumatra. It was originally erroneously published as a Himalayan species by Reichenbach, which was corrected by James Veitch 23 years after Heinrich Gustav Reichenbachs publication. Mature specimens may have up to nine leaves, but usually plants have 4–5, elliptic-obovate, acute to obtuse, 20 cm long and 8 cm wide leaves. Showy, fleshy, fragrant flowers are produced on axillary, arching to subpendent racemes or panicles. A prominent feature of this species is the midlobe of the labellum, which is oblong, obtuse-subacute, and the apex is covered in dense trichomes. The karyotype is asymmetric and nonuniform.

Although never common, this plant has vanished from much of its historical range due to habitat loss. It is the state flower of Minnesota.

<i>Oeceoclades gracillima</i> Species of orchid

Oeceoclades gracillima, sometimes known in horticulture by the synonym Oeceoclades roseovariegata, is a terrestrial orchid species in the genus Oeceoclades that is endemic to Madagascar.

The type specimen was collected in 1970 by Jean Marie Bosser from dry forest undergrowth near Tsaramasao, 20 km (12 mi) south of Sakaraha. The specific epithet longebracteata refers to the long bracts found along the inflorescence.

Rhizanthella speciosa is a species of flowering plant in the orchid family and is endemic to Barrington Tops in New South Wales.
