Ancistrochilus is a genus of the orchid family (Orchidaceae), comprising only 2 species. The name is derived from the Greek words ankistron ("hook") and cheilos ("lip"), referring to the form of the lip.
These are sympodial epiphytic plants with wide, characteristic conical or pyriform pseudobulbs, carrying two to three broad, acute, lanceolate leaves. These leaves are shed after growth has slowed down.
Three to four large and attractive, fragrant flowers, 8 cm across, then appear from the base of the mature leafless pseudobulb in a pubescent inflorescence. The petals and sepals are dark-colored, rose pink. The three-lobed lip is magenta. It ends in an elongated, narrow, curved projection.
