Acostaea is a genus of in the orchid family (Orchidaceae) comprised of six species

The species are all very small, with the lateral sepals of the flower fused into a synsepal. The lip responds to touch by snapping upward against the column, which serves to trap an insect temporarily and force it to pollinate the flower. All species have two pollinia.
Keep plant in partial shade. Plant can be grown in cool to intermediate conditions. Pot the plant in fine bark with perlite or sphagnum moss. Water regularly and keep potting media moist.
