The 35 spectacular, fee-blooming species of Spider Orchids mimic the look of spiders to attract their spider-hunting wasp pollinators. They are found in wet forests from sea level to 5.000 ft. in the tropical Americas. The yellowy green flowers are often fragrant. They appear from the base of the large pseudobulb and are usually beautifully spaced on long inflorescences that last 6 weeks or more. Most bloom generously on gracefully held, well-spaced flowering sprays in late spring or summer, but twice-a-year bloom is common. They are often interbred within the Oncidium Alliance, their presence in a pedigree signaled byt eh spidery or pointy look of the blooms. The genus was named for 18th-century botanical artist William Brass.
