Tolumnia Rafinesque (abbreviated Tolu.), 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. The plants are small, usually epiphytic, with small or absent pseudobulbs completely covered by leaves, which are triangular or circular in cross section and overlap each other at base to resemble a fan. The inflorescences arise between the leaf base and bear colorful, showy flowers. The labella are large, ornamented by variously shaped calli. The column bears prominent wings flanking the stigma. Dancing-lady orchid is a common name for some species in this genus.
The genus is primarily native to the Greater Antilles, with a few species extending into Florida, the Lesser Antilles, Mexico, Central America and northern South America (from Colombia to French Guiana).
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.
Oncidium, abbreviated as Onc. in the horticultural trade, is a genus that contains about 330 species of orchids from the subtribe Oncidiinae of the orchid family (Orchidaceae). As presently conceived, it is distributed across much of South America, Central America, Mexico and the West Indies, with one species (O. ensatum) extending into Florida. Common names for plants in this genus include dancing-lady orchid and golden shower orchid.
Brassia is a genus of orchids classified in the Oncidiinae subtribe. It is native to Mexico, Central America, the West Indies, and northern South America, with one species extending into Florida.
Epidendrum, abbreviated Epi in the horticultural trade, is a large neotropical genus of the orchid family. With more than 1,500 species, some authors describe it as a mega-genus. The genus name refers to its epiphytic growth habit.
Odontoglossum, first named in 1816 by Karl Sigismund Kunth, is a genus of about 100 orchids. The scientific name is derived from the Greek words odon (tooth) and glossa (tongue), referring to the two tooth-like calluses on the base of the lip. This genus of cool to cold growing orchids is to be found on open spots in the humid cloud forest at higher elevations from Central- and West South America to Guyana, with most species around the northern Andes. The abbreviation for this genus is Odm. in the horticultural trade.
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.
Prosthechea is a genus in the orchid family (Orchidaceae). The name is derived from the Greek word prostheke (appendix), referring to the appendage on the back of the column. Appendage orchid is a common name for this genus.
Domingoa is a genus of orchids,, consisting of four currently recognised species at home in Mexico, Central America, Cuba, Hispaniola and Mona of the Greater Antilles. The genus was established in 1913 by Rudolf Schlechter. Its name refers to Santo Domingo, an older name for Hispaniola.
Scaphyglottis is a genus of orchids native to Mexico, Central America, northern South America and parts of the Caribbean. The current concept of this genus is the result of combining several genera which have been described at various times. The concept is characterized by the growth habit: not only are new pseudobulbs added at the base of the old ones, but new pseudobulbs also grow at the apices of the old ones. Many species are quite similar and difficult to distinguish, but some are clearly distinct. A few have showy colors. The genus comprises nearly 70 species.
Sudamerlycaste is a genus of flowering plants in the family Orchidaceae. It consists of approximately 45 species. The genus was split off from Lycaste in 2002 by Fredy Archila.
Integra is a subsection of the section Schistochila of the subgenus Amphiglotium (Lindl.) of the genus Epidendrum of the Orchidaceae. Like the other subsections of Schistochila, Integra plants are sympodial orchids with no tendency to produce pseudobulbs. They bear a terminal inflorescence with a peduncle covered for most of its length with close, thin, imbricate sheaths, and terminating in a raceme. This subsection differs from the other two in that the margins of the trilobate lip are not lacerate, fringed, or denticulate. In 1861, Reichenbach listed fifteen separate species in this subsection. Some of these names are now recognized as synonyms
Elleanthus is a genus of flowering plants from the orchid family, Orchidaceae. All the species are native to the warmer parts of the Western Hemisphere.
Tetramicra is a genus of flowering plants in the orchid family, Orchidaceae, native to the West Indies. Tetramicra canaliculata has also been reported from southern Florida, but these reports have been challenged.
Lankesterella is a genus of flowering plants from the orchid family, Orchidaceae. It is found mostly in South America, with a few species extending north into Cuba, the Dominican Republic and Costa Rica.
Prescottia is a genus of flowering plants from the orchid family, Orchidaceae. It is widespread across much of Latin America and the West Indies, with one species (P. oligantha) extending into Florida.
Promenaea is a genus of flowering plants from the orchid family, Orchidaceae. It contains 18 currently accepted species, all endemic to Brazil.
