Hatiora cylindrica is a species of often epiphytic cactus in the tribe Rhipsalideae within the subfamily Cactoideae. It is native to east Brazil, where it grows in a variety of habitats, including moist forest, dunes and coastal rocks.
Hatiora cylindrica is closely related to Hatiora salicornoides, and has been included within that species.[3] Like H. salicornoides, it is a leafless perennial with many branched green stems made up of individual segments. These are strictly cylindrical as opposed to bottle-shaped in H. salicornoides. Its flowers, borne at the end of the stems, have many yellow to orange petals and open quite widely. They are followed by white fruits.[1][4]
Taxonomy
Hatiora cylindrica was first described by Nathaniel Britton and Joseph Rose in 1923.[5] It has not always been viewed as a separate species, being included in H. salicornoides as either the form or the variety cylindrica.[2][3] Molecular phylogenetic studies have confirmed its placement in the genus and in the tribe Rhipsalideae, and also shown that it is closely related to H. salicornoides (which may include some other distinct species).[6][7]
