Description

The following description of this species is based on Rebutia gracilispinaSN|4416]]SN|4540]] F.Ritter 1977 sensu stricto (Collector's number referred here is FR 1118). But plants in circulation under this name do not match up exactly with Ritter's description, most noticeably in their clearly defined ribs, unlike the much less defined ribs required by Ritter, and plants matching up to Ritter's description have not appeared in cultivation.But if we consider the numerous synonyms, form and variety of this very variable taxon (Rebutia pygmaeaSN|4540]]SN|4416]]), all the value of size, colour, flower and spines characteristic can change considerably.
