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). 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.

This genus occurs in South Florida, the West-Indies and tropical America, in wet forests.

They are commonly called ‘The Spider Orchid’ because of the flowers unique shape.

It has also been discovered that this genus is extensively pollinated by female wasps that sting at the column and the lip attempting to pull it away to consume it.

They have large elliptic-oblong pseudobulbs with one or two leaves at the apex, lateral, unbranched many-flowered inflorescences with small floral bracts.
