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.
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.
The Pleurothallidinae are a neotropical subtribe of plants of the orchid family (Orchidaceae) including 29 genera in more than 4000 species.
Myoxanthus is a genus of orchids with about 50 species, widely distributed in Central and South America. This genus is a close ally of Pleurothallis.
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.
Specklinia is a genus of orchids native to South America, Central America, and the Caribbean. It contains approximately 100 species.
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
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.
Cycnoches, abbreviated as Cyc. in the horticultural trade, is a genus of 34 currently accepted species of orchids native to South America, Central America and southern Mexico. Also called "swan orchids", they are epiphytes found in lowland and pre-montane forests.
Lepanthes guatemalensis is a species of orchid found from Mexico (Chiapas) to El Salvador.
Restrepia guttulata, commonly called the small-spotted restrepia, is a species of orchid occurring from Venezuela to Ecuador.
Orionides is a clade of tetanuran theropod dinosaurs from the Middle Jurassic to the Present. The clade includes most theropod dinosaurs, including birds.
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.
Vanilla odorata, also known as vanilla tlatepusco, is a species of flowering plant in the family Orchidaceae, native to southern Mexico, Central America, and tropical South America. With Vanilla planifolia it is a parent of the vanilla crop species Vanilla × tahitensis.
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.
