Brassia is a genus of orchids classified in the subtribe Oncidiinae. It is native to Mexico, Central America, the West Indies, and northern South America, with one species (B. caudata) extending into Florida.
Brassia species and its popular hybrids are common in cultivation, and are notable for the characteristic long and spreading tepals (in some clones longer than 50 cm), which lend them the common name spider orchid.
