Hatiora Britton & Rose sec. Korotkova & al. 2011

Hatiora Britton & Rose in Bailey, Standard Cycl. Hort.: 1432. 1915 wfo-4000017015
  • Hariota DC., Mém. Cact.: 23. 1834, nom. illeg. syn. sec. Britton & Rose 19232 wfo-40000169191 [non Hariota Adans. 1763]
    • Type: Hatiora salicornioides (Haw.) Britton & Rose
  • 1. later homonym, 2. Britton, N. L. & Rose, J.N. 1923: Cactaceae 4.


Hatiora including Rhipsalidopsis as adopted by Barthlott (1987), Barthlott & Hunt (1993), Barthlott & Taylor (1995), Hunt (2006) and Nyffeler & Eggli (2010) was found to be polyphyletic (Calvente & al. 2011a; Korotkova & al. 2011). Hatiora should therefore be restricted to species with cylindrical stems, terete pericarpels, and small yellow-orange or magenta flowers, corresponding to Hatiora in the traditional sense. Accordingly, Rhipsalidopsis in its traditional circumscription should again be accepted at generic rank.A,B,C,D,E,F,G,H

Taxon standing

Category B. The genus is monophyletic based on phylogenetic studies that support the clade based on a sufficiently dense or even complete sampling, or support a monotypic genus as a distinct lineage, but do not provide a new taxonomic treatment at the species level. In many cases, older classical taxonomic synopses or a monographic treatment exist for these genera providing a reliable assessment of the species included.


The genus Hariota was named for Thomas Hariot, a botanist of the 16th century, Hatiora being an anagram.I
