The taxonomy of the Orchidaceae (orchid family) has evolved slowly during the last 250 years, starting with Carolus Linnaeus who in 1753 recognized eight genera.[1] De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum (Jussieu) in 1789.[2] Olof Swartz recognized 25 genera in 1800.[3] Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids.[4] The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies.[citation needed] He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham in 1881 with a new classification, recognizing subtribes for the first time.[citation needed] 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).[citation needed] Dressler's 1993 book had considerable influence on later work.[5] Genera Orchidacearum was published in 6 volumes over 15 years.[6] It covers all of the orchids, including a description of each genus. It reflects the considerable progress in orchid taxonomy that had been made since 1993. In the 1990s, orchid taxonomy began to be influenced by molecular phylogenetics based on DNA sequences. The first classification that was based on such cladistic analysis of DNA data was published by Chase et alii in 2003.[7]
An update to that classification was published by Chase et alii in 2015.[8] This classification takes a different approach from Genera Orchidacearum, by consolidating many of the tribes and subtribes, and by recognizing very widely circumscribed genera. Orchidaceae has not yet been covered in The Families and Genera of Vascular Plants, tho most of the vascular plant families have by now been covered.
Changes in the taxonomy of orchids are so frequent that it is recommended that the regularly updated World Checklist of Selected Plant Families be consulted for the most current generic and species classifications. Wikispecies (Orchidaceae) closely follows this source with modifications as they become accepted. The Plant List shows lists of genera and species, but no other taxonomic information.
History
The following taxonomy follows largely the classification system of Robert Louis Dressler, an orchid specialist and adjunct curator at the Florida Museum of Natural History. This classification, published in 1981 in the book The Orchids: Natural History and Classification, was widely accepted by botanists and growers before the publication of Genera Orchidacearum. The initial scheme of 1981 was modified in 1986, twice in 1990, and then again in 1993. This comprehensive classification relies heavily on morphology, especially a few key characters, such as anther configuration and pollinarium structure. Consequently, many of the taxa are not monophyletic.
According to cladistic analyses based on morphological character states or on nucleotide sequences, the orchid family, as well as the five subfamilies within it, are all monophyletic groups. There is a great similarity with the traditional taxonomy, except for the elevation of Vandoideae to the rank of subfamily. In 1993, the relationships between the subfamilies were still unresolved. Compared to previous classifications, more of the tribes and subtribes were monophyletic, but not all of them were supported by subsequent studies. Cladistic analyses, especially those based on molecular methods provide a firmer basis for classification than intuition, and the certainty (or uncertainty) of conclusions can be quantified by measures of statistical support. While our understanding of orchid phylogeny has greatly improved in recent years, the elucidation of orchid relationships is still ongoing.
Furthermore, about 150 species and about a dozen new genera have been described each year since the beginning of the 21st century.
New developments in this taxonomy occur regularly:
- 1998: Publication of "A phylogenetic analysis of the Orchidaceae: evidence from rbcL nucleotide sequences" by Kenneth M. Cameron in the American Journal of Botany. 1999. In this study, he supports the five primary monophyletic clades (indicated as subfamilies by Dressler) and states that there is no evidence supporting the previously recognized subfamilies Spiranthoideae, Neottioideae, or Vandoideae.[9]
- 2003: the Angiosperm Phylogeny Group publishes its update of the classification for the orders and families of flowering plants. In this APG III-system, the family Orchidaceae is included in the order Asparagales.[10]
- 2003: Publication by Chase et al. of a new phylogenetic classification based on recent DNA research [7]
Taxonomy
The orchid family (Orchidaceae) is subdivided into five subfamilies, and then into tribes, subtribes, alliances (not a classification used in the International Code of Nomenclature for algae, fungi, and plants) and then genera through sub-genera down to the species. Contemporary taxonomy allows for the accepted nomenclature of natural hybrids.
According to Dressler, there are 5 subfamilies, 22 tribes, 70 subtribes, about 850 genera and about 20,000 species in this family.
A distinction between monandrous and other flowers is particularly relevant in the classification of orchids. The monandrous orchids form a clade consisting of the subfamilies Orchidoideae, Vanilloideae, and Epidendroideae. The other subfamilies, Apostasioideae and Cypripedioideae, have at least two stamens.
The following subfamilies are recognized:
- Subfamily Apostasioideae: monophyletic - the most basal of the orchids: 3 fertile anthers or two fertile anthers and a filamentous staminode.
- Subfamily Cypripedioideae: monophyletic - 2 fertile diandrous anthers, a shield-shaped staminode and a saccate (= pouch-like) lip.
- Subfamily Orchidoideae: single, fertile monandrous, basitonic anther.
- (Subfamily Spiranthoideae): now accepted as nested within a more broadly defined Orchidoideae as the sub-tribe Spiranthinae
- Subfamily Epidendroideae: includes almost 80% of the orchid species; monophyletic; orchids with an incumbent to suberect ( = ascending towards the edges) anther.
- (Subfamily Higher Epidendroideae (formerly Vandoideae): specialised clade within a more broadly defined Epidendroideae
- Subfamily Vanilloideae: an ancient clade now recognized as a distinct subfamily. But, from a molecular point of view, it is rather a sister to subfamily Epidendroideae + subfamily Orchidoideae. This subfamily is a branch at the basal dichotomy of the monandrous orchids.
Cladistically the interrelationships of these subfamilies can be shown as follows:

Subfamily Apostasioideae
The subfamily Apostasioideae belongs to the orchid family (Orchidaceae). It is a clade, but there is bootstrap support that it is a sister to the other orchid subfamilies. A bootstrap is a method for evaluating the statistical importance of positions of different branches in a phylogenetic tree (= a treelike structure giving the evolutionary development of organisms).
The apostasioid orchids are the most primitive orchids, with only two genera. Neuwiedia has 3 fertile, abaxial (= facing away from the stem) anthers, while Apostasia has two fertile abaxial anthers and a filamentous staminode (= a sterile stamen). Plants with mealy or paste-like pollen, which ordinarily are not aggregated into pellets, called pollinia, with two or three fertile long anthers, leaves with stealthing bases, elongated staminodium and labellum similar to the petals.
These primitive features make them, according to some authorities, not true orchids but rather ancestors of modern orchids. However, modern studies (Stern, Cheadle and Thorsch, 1993) point out that the apostasioid orchids are uniquely defined ( = autapomorphous). This makes them unsuitable as models to be the ancestors of the orchids.
Subfamily Cypripedioideae

Tribe Wullschlaegelieae:only one genus with two species. The tribe has been lost and the genus has now been assigned to sub-family Epidendroideae, tribe Calypsoeae.
- Genus: Wullschlaegelia
