Pleurothallis is a genus of orchids commonly called bonnet orchids. The genus name is derived from the Greek word pleurothallos, meaning "riblike branches". This refers to the rib-like stems of many species. The genus is often abbreviated as "Pths" in horticultural trade.
Stelis, or leach orchids, is a large genus of orchids, with perhaps 500 species. The generic name Stelis is the Greek word for 'mistletoe', referring to the epiphytic habit of these species. These mainly epiphytic plants are widely distributed throughout much of South America, Central America, Mexico, the West Indies and Florida. Stelis is abbreviated Ste. in the horticultural trade.
Masdevallia, abbreviated Masd in horticultural trade, is a large genus of flowering plants of the Pleurothallidinae, a subtribe of the orchid family (Orchidaceae). There are over 500 species, grouped into several subgenera. The genus is named for Jose Masdevall (?-1801), a physician and botanist in the court of Charles III of Spain.
The taxonomy of the Orchidaceae (orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera. De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789. Olof Swartz recognized 25 genera in 1800. Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids. (See External links below). The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham with a new classification, recognizing subtribes for the first time. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. Then it was published in 1883 in the final volume of Genera Plantarum. The next great contributors were Pfitzer (1887), Schlechter (1926), Mansfeld (1937), Dressler and Dodson (1960), Garay (1960, 1972), Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. Species typically have a single (monandrous), fertile anther which is erect and basitonic.
Phloeophila is a genus of orchids belonging to the tribe Pleurothallidinae. While an initial molecular phylogeny in 2013 suggested that the type species of the genus was nested within Pabstiella, further sampling showed that it in fact belongs to a unique clade distant from Pabstiella, forming the current basis of the genus.
Teagueia is a genus of orchids. They are found at high altitudes in the Andes in Colombia, Peru and Ecuador.
Acianthera aphthosa is a species of orchid. It was first described by John Lindley in 1838 as Pleurothallis aphthosa, but was assigned to the genus, Acianthera, in 2001 by Pridgeon and Mark W. Chase. It is native to Bolivia, Brazil, Colombia, Ecuador, Paraguay, and Peru.
Barbosella cogniauxiana is a species of orchid.
Barbosella crassifolia is a species of orchid endemic to Brazil.
Restrepia guttulata, commonly called the small-spotted restrepia, is a species of orchid occurring from Venezuela to Ecuador.
Pachites is a genus of flowering plants in the orchid family, Orchidaceae. It contains two known species, both endemic to South Africa. One of these, Pachites appressus, is very rare.
The Eriinae form a subtribe of Podochileae, a tribe of the orchid family (Orchidaceae). The name is derived from the genus Eria.
Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae. The Dendrobieae are mostly tropical, epiphytic orchids which contain pseudobulbs.
Orchideae is a tribe of orchids in the subfamily Orchidoideae. Historically, it was divided into 2 subtribes, Orchidinae and Habenariinae. The subtribe Orchidinae alone contains about 1,800 species. However, although some phylogenetic studies have established the monophyly of the subtribes, the generic boundaries are unclear, with many genera as traditionally circumscribed being paraphyletic or even polyphyletic. Species of genera such as Habenaria and Platanthera have been placed into both subtribes. A 2017 molecular phylogenetic study found that both subtribes did form clades, but did not formally recognize Habenariinae, because of missing genera and uncertainty over generic boundaries. The Asian species of Orchideae, in particular, have been subject to repeated changes of generic placement from 2012 onwards.
Ophidion is a genus of flowering plant in the family Orchidaceae, native to Panama to western South America and Venezuela. The genus was established by Carlyle A. Luer. It has been included in a broad circumscription of Phloeophila, but there is evidence that it forms a monophyletic taxon, and it is accepted by Plants of the World Online.
Acianthera cachensis is a species of orchid native to Costa Rica. It was first formally named Pleurothallis cachensis in 1923 and transferred to the genus Acianthera in 2016.
Acianthera angustisepala is a species of plant in the Orchidaceae family.
Stellamaris pergrata is a species of flowering plant in the family Orchidaceae, native to Costa Rica, Panama and Colombia. It was first described by Oakes Ames in 1923 as Pleurothallis pergrata. It is the only species in the monotypic genus Stellamaris. The genus is one of a number established within subtribe Pleurothallidinae in 2018 as a result of a molecular phylogenetic study.
