Otoglossum is a genus of flowering plants from the orchid family, Orchidaceae, native to South America and Central America. [1] [2] [3] [4]
They are plants of ovoid pseudobulbs spaced in long, along a creeping or ascending upward rhizomes, with thick and tanned leathery leaves. The inflorescence is axillary, racemosa, erect, starting from the sheaths of the pseudobulbs, racemous, erect, with many rather large and wavy or curly, rounded flowers.
The petals and sepals have similar shapes and sizes, with very frizzy, oval, large margins, somewhat concave. The lip is inserted at the base of the column. The spine is short, sometimes with dorsal calluses. The spine is short, apodes, sometimes with dorsal calluses before the stigmatic cavity, small wings or auricles, and terminal anther somewhat inserted under the terminal margins of the spine.
In 2001 Mark W. Chase and Norris Williams subordinated the Oncidium section Serpentia to Otoglossum. The species in this section, Oncidium serpens , Oncidium sanctipauli , Oncidium harlingii and Oncidium globuliferum , have few and widely spaced flowers at first glance, very similar to those of Oncidium varicosum , long repeating rhizomes like those of Rodriguezia , show frequent sprouting of new plants in the nodules of ancient floral stems, and morphologically have little in common with Otoglossum other than the scandal habit.

Otoglossum, according to its new definition already expanded to include the aforementioned section of Oncidium, then groups about thirteen epiphytic species, occasionally terrestrial, in rule of scandal growth, that inhabit humid, fresh and cold mountainous areas from Costa Rica to Peru until the altitude of three thousand meters, over trees or rocky escarpments. Three species registered for Brazil, two belonging to the old section of Odontoglossum and one to Oncidium.
The Orchidaceae are a diverse and widespread family of flowering plants, with blooms that are often colourful and fragrant, commonly known as the orchid family.
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 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.
Trichocentrum, often abbreviated Trctm in horticulture, is a genus in the orchid family, Orchidaceae. Dancinglady orchid is a common name for plants in this genus. It was described by Stephan Ladislaus Endlicher and Eduard Friedrich Poeppig in 1836. This genus alone makes up the monogeneric Trichocentrum alliance, a quite distinct lineage of the subtribe Oncidiinae.
The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related.
Ada, abbreviated as Ada in horticultural trade, is a genus of 16 species in the orchid family (Orchidaceae), subfamily Epidendroideae, tribe Cymbidieae, subtribe Oncidiinae, alliance Oncidium. The type species is Ada aurantiaca.
Miltonia, abbreviated Milt. in the horticultural trade, is an orchid genus comprising twelve epiphyte species and eight natural hybrids. The miltonias are exclusively inhabitants of Brazil, except for one species whose range extends from Brazil into the northeast of Argentina and the east of Paraguay.
Maxillaria, abbreviated as Max in the horticultural trade, is a large genus of orchids. This is a diverse genus, with very different morphological forms. Their characteristics can vary widely. They are commonly called spider orchids, flame orchids or tiger orchids. Their scientific name is derived from the Latin word maxilla, meaning jawbone, reflecting on the column and the base of the lip of some species, that may evoke a protruding jaw.
Bifrenaria, abbreviated Bif. in horticultural trade, is a genus of plants in family Orchidaceae. It contains 20 species found in Panama, Trinidad and South America. There are no known uses for them, but their abundant, and at first glance artificial, flowers, make them favorites of orchid growers.
Odontoglossum crispum, the curled odontoglossum, is an epiphytic orchid from the genus Odontoglossum. It is considered by many to be the most beautiful orchid of all but is also one of the most difficult to grow.
Loefgrenianthus blanche-amesiae is a showy orchid species, inhabitant of Serra do Mar mountains in Brazilian southeast. It is the only species of the monotypic genus Loefgrenianthus. It can be differentiated from its closest genus, Leptotes, both because of its pending vegetation with flat leaves and the flowers which have a saccate labellum. Loefgrenianthus blanche-amesiae is highly appreciated by orchid collectors.
Phymatochilum brasiliense is an orchid species, inhabitant of Serra do Mar mountains in Brazilian southeast and northeast, which vegetatively resembles Oncidium species, however, is more closely related to the genus Miltonia. It is the only species of the genus Phymatochilum.
Adenochilus, commonly known as gnome orchids is a genus of two species of flowering plants in the orchid family Orchidaceae, one endemic to New Zealand and the other to Australia. Both species have a long, horizontal, underground rhizome with a single leaf on the flowering stem and a single resupinate flower with its dorsal sepal forming a hood over the labellum and column.
Arthrochilus, commonly called elbow orchids, is a genus of about fifteen species of flowering plants from the orchid family (Orchidaceae) and is found in Australia and New Guinea. The flowers are pollinated by male thynnid wasps which attempt to mate with the flower and are held in place by hooks while the pollinium is transferred between insect and flower.
Gomesa is a genus of flowering plants from the orchid family, Orchidaceae. It contains about 80–100 species, all native to South America.
Koellensteinia is a genus of flowering plants from the orchid family, Orchidaceae. It is named by Heinrich Gustav Reichenbach for the Captain Carl Kellner von Koellenstein, an Austrian military officer and a botanical correspondent of Reichenbach.
Psychopsiella is a monotypic genus in the orchid family found only in the state of Rio de Janeiro in Brazil and near Caracas in Venezuela. It grows as an epiphyte in evergreen montane forests at elevations of 800 to 1,500 metres.
× Cambria is a commercial name for intergeneric hybrids among the following genera of orchids of the family Orchidaceae, subfamily Epidendroideae, tribe Cymbidieae and subtribe Oncidiinae:
Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae.
