Bulbophyllum nigericum | |
Bulbophyllum nigericum is an epiphytic or epilithic plant species in the family Orchidaceae. It is native to Cameroon (Enyandong, Mt Kupe and the Bakossi Mountains), and Nigeria, where it is found growing habitually in submontane and montane, tropical or subtropical, moist forest, at elevations roughly between 800 and 2,050 meters. It is threatened by habitat loss due to continued, extensive forest clearance for the purpose of crop cultivation. [1] It was described in 1962. [2]
In the village of Enyandong, a specimen of B. nigericum is growing on a tree in front of the house of the village Chief, where it is visible to the public. Conservationists are hopeful that this will help raise local awareness of this plant, aid in its identification, and so promote its protection. [1]
Podocarpus totara is a species of podocarp tree endemic to New Zealand. It grows throughout the North Island and northeastern South Island in lowland, montane and lower subalpine forest at elevations of up to 600 m.
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.
Hypericum tortuosum is a species of flowering plant in the genus Hypericum. It is found only in Socotra, Yemen, where it is endemic. The species is an apomorphic relative of the other Socotran species in Hypericum sect. Triadenioides and is most closely related to Hypericum scopulorum. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland.
Voanioala gerardii, commonly known as the forest coconut, is a species of flowering plant in the family Arecaceae. It is a relative of the coconut, and is generally regarded as monotypic within the genus Voanioala. However, a team of geneticists headed by Bee F. Gunn found sufficient genetic variation within Voanioala to constitute at least two and possibly four cryptospecies. Voanioala is endemic to Madagascar, and is threatened by habitat loss. Voanioala is harvested for its edible seeds and palm heart. It is estimated that there are fewer than fifteen mature trees remaining.
Ardisia koupensis is a species of plant in the family Primulaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Bulbophyllum bifarium, or two-sided bulbophyllum, is an epiphytic plant species in the family Orchidaceae, flowering in November and endemic to Cameroon. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests, where it is threatened by habitat loss. It was described in 1864 by Joseph Dalton Hooker.
Bulbophyllum gravidum is a species of epiphytic plant in the family Orchidaceae that is found in Equatorial Guinea and Cameroon. Its natural habitats are in montane, subtropical or tropical dry forests, at elevations of about 1,500 meters. The Mount Cameroon habitat, in particular, is threatened by the clearing of forest for the purpose of cocoyam farming.
Bulbophyllum jaapii is a species of plant in the family Orchidaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist montane forests. It was described botanically in 2001.
Bulbophyllum teretifolium is a species of plant in the family Orchidaceae. It is an epiphyte with cylindrical leaves and up to about forty small, white and purplish flowers and is endemic to Cameroon. Its natural habitat is subtropical or tropical, moist montane forests, where it is threatened by habitat loss.
Bulbophyllum modicum is a possibly extinct, epiphytic plant species in the family Orchidaceae. It is endemic to Cameroon, and its natural habitat is threatened. It was described in 1957.
Bulbophyllum pandanetorum is a rare species of epiphytic plant in the family Orchidaceae. It is found in Cameroon and Gabon, where its natural habitat is subtropical or tropical moist lowland forests at elevations roughly between 200 and 950 meters. It is threatened by habitat loss. It was botanically described in 1954.
Bulbophyllum porphyrostachys is a species of plant in the family Orchidaceae. It is found in Cameroon, the Republic of the Congo, and Nigeria. It was botanically described in 1951.
Bulbophyllum rubrolabellum is a species of plant in the family Orchidaceae that is endemic to Taiwan. It was first described scientifically in 1975 by Tsan Piao Lin in the journal Taiwania: Science Reports of the National Taiwan University, and is the basionym for its treatment by Ying as B. odoratissimum var. rubrolabellum(T.P.Lin) S.S.Ying in 1990.
Bulbophyllum tokioi is a species of plant in the family Orchidaceae. It is endemic to Taiwan. It was described in 1935 by Noriaki Fukuyama.
Euphorbia leuconeura is a species of flowering plant in the family Euphorbiaceae. Its common name is Madagascar jewel. It is endemic to Madagascar where its natural habitat is forest undergrowth in rocky areas. It can grow to a height of 1.8 m (6 ft), as a branching small tree, and propagates by shooting its seeds several feet into the air. It is threatened by habitat loss.
Bulbophyllum micropetalum is a species of plant in the family Orchidaceae. It is found in Cameroon and the island of Bioko in Equatorial Guinea. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
Bulbophyllum platybulbon is a species of plant in the family Orchidaceae. It is native to Cameroon and Gabon. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
Ocotea porosa, commonly called imbuia or Brazilian walnut, is a species of plant in the Lauraceae family. Its wood is very hard, and it is a major commercial timber species in Brazil.
Bulbophyllum subligaculiferum is a species of orchid in the genus Bulbophyllum endemic to the forests of Cameroon and Gabon. As a result of its decreasing population, it has been listed as 'Endangered' under criteria B2ab(iii,v) of the IUCN Red List of Threatened Species 2018.
Bulbophyllum nocturnum is a species of epiphytic orchid that grows in New Britain. It was described in 2011, and is the first species of orchid known to consistently flower during the night, and close its flowers during the day.
