'''''Brassia''''' is a [[genus]] of [[orchid]]s classified in the ''[[Oncidiinae]]'' subtribe.
The genus was named after [[William Brass]], a British botanist and illustrator, who collected plants in Africa under the supervision of Sir [[Joseph Banks]]. Its abbreviation in the horticultural trade is Brs.

==Description==
''Brassia'' [[species]] and its popular [[hybrid]]s are common in cultivation, and are notable for the characteristic long and spreading [[tepal]]s (in some clones longer than 50 cm), which lend them the common name "spider orchid".

This [[epiphyte|epiphytic]] genus occurs in South Florida, the West-Indies and tropical America, in wet forests from sea level to altitudes under 1500 m, with the Peruvian [[Andes]] as its center. Occurrence is mostly restricted to a certain area, but ''Brassia caudata'' can be found over the whole geographic area.

They have large elliptic-oblong [[pseudobulb]]s with one or two leaves at the apex, lateral, unbranched many-flowered [[inflorescence]]s with small floral [[bract]]s. The [[labellum|lip]] is not attached to the column. The [[pollinarium]] shows a narrow stipe. There are two distichous, foliaceous [[sheath]]s around the base, from which the inflorescence emerges.

''Brassia'' has a very specific method for pollination : it uses entomophily : [[pollination]] by insects and in this case specifically by female spider-hunter wasps of the
genera ''[[Pepsis]]'' and ''[[Campsomeris]]''. Mistaken by the [[mimicry]] of ''Brassia'', the wasp stings the [[labellum|lip]], while trying to grasp its prey without any success. By these movements the wasp comes into contact with the pollinarium, that then sticks to its head. By flying to another ''Brassia'' flower, this flower gets pollinated.
