Hatiora

Morphological Summary

Hatiora is a genus of epiphytic cacti from the Brazilian Atlantic Forest (Mata Atlântica), characterized by jointed, spineless stems adapted to grow on branches and mossy rocks in humid, shaded environments. Flowers are relatively small, diurnal, yellow to pink or red depending on the species. The best-known species are the Easter cactus (H. gaertneri) and H. rosea, with intensely pink flowers very popular in floriculture. Hatiora was segregated from Rhipsalis and Hariota, and is recognized as an independent genus in modern classification.
