Hapaline is a genus of flowering plants in the Araceae family. It contains 7 species that are found from southern China to Malaysia. They are usually found growing in humid forests in pockets of humus amongst basalt or limestone rocks. The genus was originally given the name Hapale by Heinrich Wilhelm Schott in 1857, but it was changed to Hapaline a year later when it was discovered that a genus of South American marmosets already had been assigned the name in 1811. Hapaline is unique in that it is the only genus in the tribe Caladieae.
