Weingartia steinbachii (Werderm.) Brandt

Weingartia (Sulcorebutia) steinbachii was first described (as Rebutia steinbachii) by  E. Werdermann in Notizblätt des Botanischen Gartens und Museums zu Berlin-Dahlem 11: 268, in 1931.

The species, or superspecies, has a huge variation of forms, spination and flower colour. Hentzschel and Augustin (2008) recognise two subspecies in addition to the nominate, these being W. s. krugerae and W. s. verticillacantha. Within W. s. krugerae, three varieties are recognised, these being the nominate, var. hoffmannii, and var. tunariensis. Within W. s. verticillacantha, three varieties are recognised, these being the nominate, var. taratensis, and var. horrida. There is a large number of other varietal names in common use among growers.
