Megastylidinae is an orchid subtribe in the tribe Diurideae.
Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
The Pleurothallidinae are a neotropical subtribe of plants of the orchid family (Orchidaceae) including 29 genera in more than 4000 species.
In the botanical classification of plants, Aeridinae Pfitzer is a subtribe of the tribe Vandeae whose representatives all have a monopodial growth habit and do not possess pseudobulbs.
Cypripedioideae is a subfamily of orchids commonly known as lady's slipper orchids, lady slipper orchids or slipper orchids. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium. They are characterised by the slipper-shaped pouches of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily.
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.
The Oncidiinae is a subtribe within the Orchidaceae that consists of a number of genera that are closely related.
Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as Epipactis and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi.
The Cymbidieae is a tribe of plants within the family Orchidaceae. The group is divided into the following subtribes:
Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae.
Arethuseae is a mid-sized tribe of orchids in the subfamily Epidendroideae. This tribe was initially categorized by John Lindley in 1840. Its largest subtribes are Arethusinae and Coelogyninae.
The Vandeae is a large monophyletic tribe within the family of orchids.
The tribe Epidendreae of the Orchidaceae comprises six subtribes:
Dendrobieae is a tribe in the subfamily Epidendroideae, in the family Orchidaceae. The Dendrobieae are mostly tropical, epiphytic orchids which contain pseudobulbs.
Cranichideae is an orchid tribe in the subfamily Orchidoideae.
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.
Goodyerinae is an orchid subtribe in the tribe Cranichideae.
Spiranthinae is an orchid subtribe in the tribe Cranichideae.
Calypsoinae is an orchid subtribe in the tribe Epidendreae of subfamily Epidendroideae. It has previously been recognized as tribe Calypsoeae in the subfamily Epidendroideae.
Malaxideae is an orchid tribe in the subfamily Epidendroideae.
Mark Alwin Clements (b. 1949) is an Australian botanist and orchidologist. He obtained his doctorate at the Australian National University defending his thesis entitled Reproductive Biology in relation to phylogeny of the Orchidaceae, especially the tribe Diurideae.
