Etymology
| 🌵 Author(s) | Yoshio Itō |
Greek dichroös ‘two-colored’ + Rebutia (the compound should correctly be Dichroörebutia). For the color of the spines? Publication not seen. Curt Backeberg (Cactaceae 3: 1555) mentions Chinorebutia, Dichrorebutia and Chionorebutia as subgenera of Rebutia for “species with longer and white or differently colored spines”.
Listed only as a subgenus by Backeberg (l.c.) and Mottram (Cactician 4. 2014), but (probably erroneously) as a genus on several websites.
