Subspecies, varieties, forms and cultivars of plants belonging to the Rebutia heliosa group

• Rebutia densipectinata KK849 f.ma brevispina hort.: This is one of the most remarkable red blooming Rebutias with short, tiny silvery brown spines and purple tinged stem reminding of Sulcorebutia rauschii.

• Rebutia heliosa Rausch: It is a miniature plant that readily forms a clustering mound of tiny heads. The spines are very short, silvery, dense and pectinate, covering almost completely the small stems in a spiral pattern. Blooms orange.
