Rhipsalidopsis rosea v. remanens
Backeberg in vol. 6 of his "Die Cactaceae", 1962, pages 3644
- 3646, gives a discussion on Rhipsalidopsis rosea. His conclusion is
that Rh. rosea is variable in its habit. He also diagnoses a new var.:
Rhipsalidopsis rosea v. remanens Backebg. n. var.:
Differt a typo ramis gracilioribus, plurium quinque- vel quadricostatis;
areolis setiferis; saetis ca. ad 8.
Differs from the type by smaller branches, mostly 5 or 4 -angled; with
areoles bearing up to 8 bristles.
Backeberg states: this var. is generally very slowly growing, but has
same flowers as the typus.
