Extra Info:
For many year Sulcorebutias found by Swoboda and others (HS78 etc.) have been called S. pulchra. This mistake was cleared when de Vries et al. discovered VZ642, a population of plants which exactly match the first-description for Reb. pulchra. Several other finds in the same area of  the natural reserve of El Palmar suggest, that the Cárdenas plants for S. pulchra, inflexiseta and caracarensis might have come more or less out of the same population. The description of the flowers of these 3 “species” is almost identical except for little differences in size.
