Acampe, abbreviated as Acp in horticultural trade, is a genus of monopodial, epiphytic vandaceous species of orchids, distributed from tropical Asia from India , eastwards to China and southwards to Malaysia, and the Philippines as well as from tropical Africa, Madagascar and islands of the Indian Ocean.[2] The name Acampe was derived from the Greek word akampas, meaning "rigid", referring to the small, brittle, inflexible flowers.

Acampe produce slow-growing, medium-sized vines that form very large vegetative masses in nature. They are noted for their thick, leathery, distichous leaves. They produce fragrant small to medium-sized yellow flowers, barred with orange or red stripes, in a few to many-flowered racemose inflorescence. The brittle sepals and petals look alike. The ear-shaped, fringed, white labellum (lip) is saccate (sac-shaped) or has a spur, and has red markings at its base. The fleshy column is short and has two waxy pollinia.[3]

Due to their large size and small flowers, they are rarely cultivated.
