Porroglossum (from Greek "far off" and "tongue", referring to the position of the lip) is a genus of orchids native to the Andes of South America. The center of diversity lies in Ecuador, with many of the species endemic to that country, though others are found in Colombia, Venezuela, Peru, and Bolivia. [2] [3] This genus is abbreviated Prgm in horticultural trade.
The lip in this genus is unique in the family. It is hinged and has a mechanism that snaps shut when stimulated by a pollinator, thus trapping the insect to ensure that the pollinia will be removed and later transferred to the receptive surface. The lip opens after 30 minutes or so to release the insect, but also closes at night and reopens at dawn.
Species accepted as of June 2014:
Brassia is a genus of orchids classified in the subtribe Oncidiinae. It is native to Mexico, Central America, the West Indies, and northern South America, with one species extending into Florida.
Sobralia is a genus of orchids native to Mexico, Central and South America. The plants are more commonly terrestrial, but are also found growing epiphytically, in wet forests from sea level to about 8,800 ft. The genus was named for Dr. Francisco Sobral, a Spanish botanist. The genus is abbreviated Sob in trade journals.
Scaphosepalum is a genus of plants belonging to the family Orchidaceae. The species in this genus are mostly found in Central and South America, with one species extending into southern Mexico. In accordance with their genus name, many species in this genus produce unusual and distinctive flowers; some possessing cushion-like characteristics reminiscent of an African buffalo's horns, others possessing characteristics of snake fangs.
Barbosella is a genus of mostly creeping orchids. The genus has about 20 species, widespread across the West Indies and Latin America from Mexico and the Lesser Antilles to Argentina. Named after João Barbosa Rodrigues, an investigator of Brazilian orchids. They have solitary flowers with a unique lip base that works like a ball and socket.
Dryadella is a genus of miniature orchids, formerly included in the genus Masdevallia. Plants are typically composed of a tuft of leaves from 3 to 6 cm long. The small (1–2 cm) flowers are often conspicuously spotted, and are borne at the base of the leaves. There are about 60 species, distributed from southern Mexico to southern Brazil and northern Argentina. In cultivation many of the species seem to respond well to being grown on cork or treefern rather than in pots. The attractive species Dryadella edwallii, commonly known as 'Partridge in the Grass' can be easily grown into a spectacular specimen plant, full of flowers. The genus name of Dryadella refers to Dryad, a tree nymph or tree spirit in Greek mythology.
Lepanthopsis, abbreviated as Lpths in horticultural trade, is a genus of orchids with about 43 currently known species. They are distributed mostly in the Andes and the Caribbean, with some species in Central America, southern Mexico and Florida. Lepanthopsis orchids are very small, often with flowers measuring less than 1 centimeter across.
Andreettaea is a genus of flowering plant in the family Orchidaceae, native to southern Mexico, the West Indies and tropical South America. The genus was established in 1978. Some sources treat the genus as a synonym of Pleurothallis.
Specklinia is a genus of orchids native to South America, Central America, and the Caribbean. It contains approximately 100 species.
Acianthera is a genus of orchids native to the tropical parts of the Western Hemisphere, especially Brazil. It was first described in 1842 but was not widely recognized until recently. Most of the species were formerly placed under Pleurothallis subgenus Acianthera. This splitting is a result of recent DNA sequencing.
Teagueia is a genus of orchids. They are found at high altitudes in the Andes in Colombia, Peru and Ecuador.
Trichosalpinx, commonly known as the bonnet orchid, is a genus of about 100 species of neotropical orchid. The genus is widespread across most of Latin America from northern Mexico to Bolivia, as well as the West Indies.
Trisetella is a genus of orchids, native to Central and South America. Twelve of the 23 currently known species are endemic to Ecuador. They bear small flowers with fused sepals and fused petals. The synsepal bears three hair-like tails, which is the namesake of Trisetella.
Ornithocephalus is a genus of orchids comprising more than 50 known species widespread in South America, Central America, Southern Mexico, Trinidad and the Windward Islands.
Cischweinfia is a genus of flowering plants from the orchid family, Orchidaceae. It was named after Harvard orchidologist Charles Schweinfurth. It has eleven currently recognized species, all native to Central America and northwestern South America.
Telipogon is a genus of flowering plants from the orchid family, Orchidaceae. It is a large genus with dozens of species, native to South America, Central America, Hispaniola and southern Mexico.
Kefersteinia is a genus of flowering plants from the orchid family, Orchidaceae. It has about 40-50 species, widespread across much of Latin America. The genus was named for Keferstein of Kröllwitz, an orchidologist.
Andinia is a genus of flowering plants belonging to the family Orchidaceae.
