Anisopetala is a southeast Asian genus of epiphytic orchids with elongate, narrow stems (Clements 2003).

Characters (from Clements 2003): Plants epiphytic herbs. Stems elongate, narrow, relatively fleshy. Leaves along almost their entire length when young, deciduous prior to flowering. Inflorescence lateral, the peduncles short and usually pendulous, bearing 1–14 flowers. Flowers showy, with a distinct mentum fusion of the basal part of the lateral sepals, and always held away from the ovary and pedicel; free parts of sepals and petals spreading; labellum with distinct claw, with or without a small projection on the upper surface near the base, the apical part spreading, usually without distinct sidelobes, and with a bilobed apex.
