Description
Gymnocalycium damsiiSN|13315]]SN|13319]] var. rotundulum (Gymnocalycium anisitsiiSN|13319]]SN|13315]]) is a usually solitary colourful cactus common in cultivation, characterized by rounder and scarcely raised tubercles. However it is very similar (if not identical) to the standard G. damsii (G. anisistsii) and it is probably the exact same plant.
Note
Seems to be a pretty variable plant you might get some other names which are effectively the same plant.... and also not sure all plants identified as this are really this.
Spines
Nearly useless in terms of defence.
Stem
Up to 10 cm tall, 8-10 cm in diameter colourful and highly decorative, with characteristic horizontal clear and dark strips. The clear areas (above the areoles) are pastel-grey-pink while the dark zone (below the areoles) are deep olive-green to brown-purple.
