Stanhopea is a genus of the orchid family (Orchidaceae) from Central and South America. The abbreviation used in horticultural trade is Stan. The genus is named for the 4th Earl of Stanhope (1781-1855), president of the Medico-Botanical Society of London (1829-1837). It comprises 55 species and 5 natural hybrids. These epiphytic, but occasionally terrestrial orchids can be found in damp forests from Mexico to Trinidad to NW Argentina. Their ovate pseudobulbs carry from the top one long, plicate, elliptic leaf.
Tibouchina is a neotropical flowering plant genus in the family Melastomataceae. Species of this genus are subshrubs, shrubs or small trees and typically have purple flowers. They are native to Mexico, the Caribbean, and South America where they are found as far south as northern Argentina. Members of this genus are known as glory bushes, glory trees or princess flowers. The name Tibouchina is adapted from a Guianan indigenous name for a member of this genus. A systematic study in 2013 showed that as then circumscribed the genus was paraphyletic, and in 2019 the genus was split into a more narrowly circumscribed Tibouchina, two re-established genera Pleroma and Chaetogastra, and a new genus, Andesanthus.
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.
Within the Orchidaceae, Hormidium was originally a subgenus of the genus Epidendrum, but was later raised to a full genus. It is now considered not to be distinct from the genus Prosthechea, of which it is a synonym. Most of the species of Hormidium have been transferred to Prosthechea, although others are now classified in Encyclia, Epidendrum, Homalopetalum, and Lepanthes.
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.
Specklinia is a genus of orchids native to South America, Central America, and the Caribbean. It contains approximately 100 species.
Tolumnia, is a genus in the family Orchidaceae. Previously known as the "equitant oncidiums," the species were segregated from the mega-genus Oncidium by Guido Braem in 1986. Dancing-lady orchid is a common name for some species in this genus.
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.
Notylia, abbreviated Ntl in horticultural trade, is a genus of orchids. It consists of 56 recognized species, native to Mexico, Central America, Trinidad and South America.
Campylocentrum is a genus of rare orchids native to Mexico, the West Indies, Central America and South America. One species (C. pachyrrhizum) extends its range into Florida.
Cirrhaea is a genus of orchids, comprising 7 recognized species, all endemic to Brazil.
Oncidium gardneri is a species of orchid native to southern and southeastern Brazil.
Ida, synonym Sudamerlycaste, is a genus of flowering plants in the family Orchidaceae. It consists of approximately 45 species and hybrids. The genus was split off from Lycaste in the early 2000s.
Eltroplectris, the long-claw orchid, is a genus of flowering plants from the orchid family, Orchidaceae. It is native to South America, the West Indies, and Florida.
