Pseudolithos dodsoniana

The small dark purple-black flowers.
 

Cultivation: P. dodsonianus although not easy to grow, is nonetheless easier and quicker growing than the others Pseudolithos and grows quite well in a greenhouse, it enjoy surprising amounts of water when they're growing. They need a very fast draining soil and protection from cold and damp, but doesn’t like to get bone dry, even in winter, when plants must receive regular light watering, this species is comparatively quite frost resistant, but the minimum temperature must not lower below 0° C (anyway it can tolerate occasional light frost for short period), with adequate water supply this species can flower all the winter long . They come well from seed, do reasonably well in cultivation if given the right conditions. Since they're slow growing branching plants they can stay for many years in a small container
But they remain quite expensive rarities.

Despite their obvious differences in growth form, and the fact that they do not naturally hybridise in habitat, these two species do artificially produce some interesting grey or brown skinned hybrids which have pyramidal or elongated shape.

Origin: P. dodsonianus  is a beautiful plant originated from Northern Somalia and Oman

This species together with P. caput-viperae and P. mccoyi are the only freely branching members of the genus. Originally classified as a Caralluma, was transferred into Pseudolithos, as P. dodsonianus and now again in the genus Anomalluma as A. dodsoniana because of stem morphology and DNA researches.
