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

  • Rebutia glomerispina Cárdenas: (Sulcorebutia)
  • Rebutia polymorpha Cárdenas: (Sulcorebutia) It has been named polymorpha (which means "many forms") for the variability of the plant in habitat. It has white, yellow, brown or almost black spines that are frequently absent on new areoles at plant apex. Distribution: Cochabamba.
  • Rebutia steinbachii Werderm.: (Sulcorebutia) It is a very variable clumping species (rarely solitary). Plants are often dimorphic: short spined juvenile forms transform at maturity to strongly spined forms. Some of these juvenile forms, however, may persist without transformation to the mature form.
  • Rebutia steinbachii f. cristata hort.: crested form. There are several crested clones often very different one to each other.
  • Rebutia steinbachii subv. aguilari Gertel: (Sulcorebutia) Plants with attractive mahogany red spines, dark purple budies and rings of light purple flowers in spring.
  • Rebutia steinbachii subs. tiraquensis (Cárdenas) D.R.Hunt: (Sulcorebutia) The stems are almost completely concealed by fine variously coloured spines. Distribution: North and east of Cochabamba.
  • Rebutia steinbachii subs. verticillacantha (F.Ritter) Donald ex D.R.Hunt: (Sulcorebutia) has 13-21 spiraling ribs, no central spines, and 12-14 pectinate radials. Distribution: Arque, Cochabamba.
