Prosthechea cochleata, formerly known as Encyclia cochleata, Anacheilium cochleatum, and Epidendrum cochleatum and commonly referred to as the clamshell orchid or cockleshell orchid, is an epiphytic, sympodial New World orchid native to Central America, the West Indies, Colombia, Venezuela, and southern Florida. P. cochleata is common in cultivation, and is valued for its uniquely shaped and long-lasting flowers on continually growing racemes. Several hybrids have been produced with this species, including the popular Prosthechea Green Hornet. (still often listed as Encyclia Green Hornet)
