Eulophia petersii (Rchb.f.) Rchb.f. | |
Eulophia petersii is a succulent species of flowering plant in the family Orchidaceae, from southern and eastern Africa.
It is found in arid environments in the Northern Frontier Province, Kenya, the eastern coast of Africa and the former Transvaal region of South Africa.
Eulophia petersii is an unusual member of the orchid family in that it lives in a harsh environment, often in full sun. It is often found growing in acidic sandy soils or in rock outcroppings.
The leaves of this orchid are thick, fleshy and very fibrous and have a sharp serrated edge and resemble those of some species of Aloe or some Sansevieria species and are usually 40 cm long. There are usually two to five leaves per pseudobulb. The pseudobulbs are yellow with a pronounced ribbing and 30 cm long with a diameter of 3–4 cm. The form that grows on the southern tip of the Arabian peninsular (Yemen) is much smaller and more compact in habit.
The flowers are widely spaced on a 2 m inflorescence that can sometimes be branched. The flowers themselves are green with a wrinkled white lip. There is quite a bit of variability in the flowers coloration between plants. Sometimes the sepals and petals can be circinnate.
Eulophia petersii can be bred with Grammangis ellisii to form a hybrid named Eulomangis Jumbo Pete.
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.
Eulophia, commonly known as corduroy orchids, 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.
Oncidium, abbreviated as Onc. in the horticultural trade, is a genus that, as of December 2023, contains about 340 species of orchids from the subtribe Oncidiinae of the orchid family Orchidaceae. It is distributed across tropical and subtropical America from Mexico, Central America and the West Indies to northern Argentina, with one species (O. ensatum) extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid.
Anguloa, commonly known as tulip orchids, is a small orchid genus closely related to Lycaste. Its abbreviation in horticulture is Ang. This genus was described by José Antonio Pavón and Hipólito Ruiz López in 1798. They named it in honor of Francisco de Angulo, Director-General of Mines of Spain.
Grammatophyllum speciosum, also called giant orchid, tiger orchid, sugar cane orchid or queen of the orchids, is a species of orchid native to Laos, Myanmar, Thailand, Vietnam, Borneo, Indonesia and Malaysia. It has also been recorded in the Philippines, New Guinea and the Solomon Islands. It is listed by the Guinness Book of World Records as the world's tallest orchid, with specimens recorded up to 7.62 metres (25 ft) in height.
Ansellia is considered a monotypic genus of orchid, with only one species, Ansellia africana, commonly known as African ansellia or leopard orchid, however, it may in fact be a complex group of species which share common floral structure and growth habit.
Himantoglossum hircinum, the lizard orchid, is a species of orchid in the genus Himantoglossum found in Europe and North Africa.
Dendrobium kingianum, commonly known as the pink rock orchid, is a flowering plant in the orchid family Orchidaceae and is endemic to eastern Australia. It usually grows on rocks, rarely as an epiphyte, and has thin, spreading leaves and spikes of up to fifteen, usually pink flowers in late winter to spring. It is popular in Australian native horticulture and is a commonly cultivated orchid among Australian orchid species growers.
Hammarbya paludosa is a small orchid commonly known as bog orchid, bog adder's-mouth or bog adder's-mouth orchid. It grows in bogs in temperate and subarctic regions of the Northern Hemisphere.
Bulbophyllum frostii, commonly known as Frost's bulbophyllum or Dutchman's shoes is a species of orchid, In the wild it grows as an epiphyte, inhabiting evergreen seasonal lowland rainforests in Vietnam and more rarely in Thailand, including the Malay peninsula. It was more recently reported growing in the Yunnan province of China during a series of botanical surveys between 2017 and 2020. This plant is usually found at elevations of around 1500m above sea level.
Eulophia guineensis is a species of orchid. It is the type species of the genus Eulophia and is commonly known as the Guinea Eulophia or the broad-Leaved ground orchid. It is found in the Cape Verde Islands, much of tropical Africa and part of the Arabian Peninsula. It is a terrestrial orchid that can grow to a metre or so tall, and is found in lowland and upland woods and scrubland.
Eulophia pulchra, commonly known as the gonzo orchid, is a plant in the orchid family and is native to areas from Tanzania and Mozambique to the Western Pacific Ocean. It is a terrestrial orchid with crowded, above-ground pseudobulbs, two or three leaves and pale yellowish green flowers with dull purple or red markings. It grows in plant litter in rainforests.
Eulophia speciosa is a species of terrestrial orchid found from Ethiopia to South Africa and in Yemen and Saudi Arabia. The plants usually grow in grasslands in sandy soils or in clay.
Eulophia streptopetala is a species of orchid. It can be found from Eritrea to South Africa and also in Yemen. This species is widespread and is usually found at forest margins, in bushy scrub, or in grasslands from the coast to 2550 meters above sea level. The plant produces a tall inflorescence originating from the subterranean pseudobulb that continues to produce flowers over several months. The flowers are approximately one centimetre in diameter with yellow petals and brownish green striped sepals.
Cattleya cernua, commonly known as the nodding sophronitis, is a species of orchid occurring from Brazil to northeastern Argentina. It was the type species of the genus Sophronitis until the genus was made synonymous with Cattleya. Twenty plants of C. cernua have received a total of 22 AOS awards. The described flowers range from 1.9 cm to 3.2 cm horizontal spread and from 2.0 cm to 3.0 cm vertical spread.

It is an evergreen, terrestrial herb with large, crowded pseudobulbs, large pleated leaves and flowers that are reddish brown on the inside and white outside.
Oeceoclades longebracteata is a species of terrestrial orchid in the genus Oeceoclades that is endemic to southwestern and south-central Madagascar. It was first described by the French botanists Jean Marie Bosser and Philippe Morat in 2001. 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.
Oeceoclades peyrotii is a species of terrestrial orchid in the genus Oeceoclades that is endemic to southwestern Madagascar. It was first described by the French botanists Jean Marie Bosser and Philippe Morat in 2001. The type specimen was collected in 1974 by Bosser and Morat from the woods near Ankazoabo, but it has also been found 40 km (25 mi) south of Sakaraha, near Mahaboboka, and near Morombe. The specific epithet peyrotii was given to this species in honor of Dr. Jean-Pierre Peyrot whose observations and collections have led to a better understanding of Malagasy orchids.
