Vandeae Genera
The Vandeae is a large monophyletic tribe within the family of orchids. Scope This tribe contains 1,700 - 2,000 species in more than 150 genera. Epiphytic These orchids are pantropical epiphytes and occur in tropical Asia, the Pacific Islands, Australia and Africa. Many of these orchids are horticulturally important, especially ''Vanda'' and ''Phalaenopsis''. Subtribes This tribe is subdivided into four subtribes:Simo-Droissart, M., Plunkett, G.

Spur (biology)
The botanical term “spur” is given to outgrowths of tissue on different plant organs. The most common usage of the term in botany refers to nectar spurs in flowers. * nectar spur * spur (stem) * spur (leaf) See also *Fascicle *Sepal *Petal *Tepal A tepal is one of the outer parts of a flower (collectively the perianth).

Angraecum Magdalenae
The genus ''Angraecum'', abbreviated as Angcm in horticultural trade, common name comet orchid, contains about 220 species. Etymology Despite the genus's distribution being largely confined to Africa and its offshore islands, the genus name is a latinization of the Indonesian and Malay word anggrek (“orchid”), itself ultimately from Javanese ꦲꦔ꧀ꦒꦿꦺꦏ꧀ (anggrék, “orchid”). Description Angraecums are quite varied vegetatively and florally, and are adapted to dry tropical woodland habitat and have quite fleshy leaves as a consequence. Most are epiphytes, but a few are lithophytes. The long-lasting flowers are racemose and grow from the leaf axils. They are mostly white, but a few are yellow, green or ochre. They all have a long spur at the back of the labellum (lip). In the case of ''Angraecum sesquipedale'', a species from Madagascar, on observing the spur in the lip, Charles Darwin made the hypothesis that, since the nectar was at the bottom of the sp ...

Thrixspermum Calceolus
''Thrixspermum calceolus'', commonly called the small shoe-carrying thrixspermum, is a species of orchid 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. Along with the Asteraceae, they are one of the two largest families of flowering ... native to Thailand, Vietnam, Borneo, Malaysia and Sumatra. They can be found as epiphytes or lithophytes in lower evergreen and semideciduous montane forests. The orchids are climbing or creeping with their roots found along the length stems. White flowers with fragrant can be found in summer. There are often 2 to 3 flowers per node. left, 250px, 1846 illustrationMiss Drake (1803-1857) del., G.

Bromheadia Brevifolia
''Bromheadia brevifolia'' is a small epiphytic orchid species in the genus '' Bromheadia''. It is native to the Malay Peninsula, where it is found in the Malaysian states of Pahang and Perak, and on the island of Borneo in the Malaysian states of Sabah and Sarawak, as well as in Brunei.Kruizinga, J., H.J. van Scheindelen, and E.F. de Vogel. 1997. Revision of the genus ''Bromheadia'' (Orchidaceae). ''Orchid Monographs'', 8: 79-118, figures 29-55, plates 4b-5b. The length of its stems are covered by the leaf sheaths.

Polystachya Virginea
''Polystachya'', abbreviated Pol in horticultural trade, and commonly known as yellowspike orchid, is a flowering plant genus in the orchid family (Orchidaceae). This rather distinctive genus was described by William Jackson Hooker in 1824 and is the type genus of the subtribe Polystachyinae. It contains about 100 species widespread across many of the tropical areas of the world.

Aerangidinae
Aerangidinae is classified as a subtribe within the tribe Vandeae in the family Orchidaceae. However, it is likely to soon become a synonym of Angraecinae with the genera below re-allocated to this sub-tribe. As traditionally circumscribed, it consists of 36 genera and about 300 species. The type genus of this subtribe is ''Aerangis''. Members of this group are epiphytic orchids having a monopodial habit and are endemic to tropical Africa and Madagascar. They are distinguished from the other subtribes in Vandeae by having an elongate rostellum, an elongate spur, and two pollinia. Most genera in the group indicate pollination by moths, however leaf beetles (family Chrysomelidae) are reported as frequent visitors, but it is unknown whether they are vectors for pollination. Genera Genera in this subtribe are listed below: *''Aerangis'' *'' Ancistrorhynchus'' *''Angraecopsis'' *'' Azadehdelia'' *'' Beclardia'' *'' Bolusiella'' *'' Cardiochilos'' *'' Chamaeangis'' *'' Chauliod ...

Hederorkis
''Hederorkis'' is a genus of flowering plants from the orchid family, Orchidaceae. It contains two known species, both native to islands in the Indian Ocean (Seychelles and Mauritius). Description As opposed to ''Polystachya'' (the largest genus in the subtribe), ''Hederorkis'' lacks pseudobulbs.

Pollinium
A pollinium (plural pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen are well attached to one another, but in other orchids there are two halves (with two separate viscidia) each of which is sometimes referred to as a pollinium. Most orchids have waxy pollinia. These are connected to one or two elongate stipes, which in turn are attached to a sticky viscidium, a disc-shaped structure that sticks to a visiting insect. Some orchid genera have mealy pollinia. These are tapering into a caudicle (stalk), attached to the viscidium. They extend into the middle section of the column. The pollinarium is a collective term that means either (1) the complete set of pollinia from all the anthers of a flower, as in Asclepiadoideae ...

Rostellum
The rostellum is a projecting part of the column in Orchidaceae flowers, and separates the male androecium from the female gynoecium, commonly preventing self-fertilisation. In many orchids, such as ''Orchis mascula'', the pollinia or pollen masses, are connected by stipes down to adhesive discs attached to the rostellum which forms cups keeping the discs or balls sticky. In ''Catasetum'' flowers the rostellum projects forward at each side as an "antenna", and the pollen masses are connected by a bent stalk or pedicel to a sticky disc kept moist at the back of the flower. When an insect touches an "antenna", this releases the bent pedicel which springs straight and fires the pollinium, sticky disc first, at the insect. Charles Darwin described in ''Fertilisation of Orchids ''Fertilisation of Orchids'' is a book by English naturalist Charles Darwin published on 15 May 1862 under the full explanatory title ''On the Various Contrivances by Which British and Foreign Orchids Ar ...
