Brassia

COMMON NAME

Spider orchid

TYPE

Orchid

FAMILY

Orchidaceae

NOTES

Large elliptic-oblong pseudobulbs with one or two leaves at the apex, lateral, unbranched many-flowered inflorescences with small floral bracts and are notable for the characteristic long and spreading tepals.  Brassia has a very specific method for pollination; it uses entomophily - pollination by insects - and in this case specifically by female spider-hunter wasps. Mistaken by the mimicry of Brassia, the wasp stings the 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.
