Description: Sulco SN'>SN|12098' alt='5221'>Rebutia tiraquensis#SN#11512'>Sulco[[Rebutia tiraquensisSN' style='border:none;'> is one of the innumerable local form of the very variable Rebutia steinbachiiSN|5221]]SN|5221]] (= Sulco SN'>5220' alt='11512'>Rebutia steinbachii#SN#5221'>Sulco[[Rebutia steinbachiiSN' style='border:none;'>). Its stems are almost completely concealed by fine silvery white and dark-reddish or mahogany coloured spines.
Habit: It is a clustering species (rarely solitary) readily forming, especially in cultivation, clumps of many heads.
Root: Mostly non-succulent, fibrous roots.
Stem: Soft globular, flattened and somehow apically depressed, greysh-green to dark green sometime very dark magenta-green.
Ribs: 12-26, spiralling, forming oblong rhomboid tubercles with well-defined grooves.
Areoles: Elongated with short grey felt (almost naked) 3-6 long, 1,5-2 mm large.
Spines: Erect, thin, bristle-like and flexible, bicoloured silvery white and dark-reddish or mahogany with darker tips.
Flowers: Rarely more than 3,5 cm long and 4,5 in diameter. Bright pink to light purple, numerous in a ring at the base of the plant.
Blooming season: April-May and remain open for up to five days.

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.
Rebutia taratensis Cárdenas: (Sulcorebutia) Tiny plant, clustering from carrot-like tap-roots readily forming small clumps of many heads. Stems dark green to purplish. Flowers magenta-red.
Sulcorebutia augustinii Hentzschel: has mini stems almost hidden under the dense covering of tiny amber and pectinate spines. Rings of light purple flowers brighten up the plant in spring. Distribution: Pasorapa (Villa Redención Pampa Zudañez) Cochabamba.
Sulcorebutia augustinii f. cristata hort.: Beautiful crested form with nice amber-honey pectinated spines, very attractive even without flowers.
Sulcorebutia clizensis Rausch: has dark green bodies, protruding brown spines and reddish flowers, barely distinguishable from Sulcorebutia cochabambina Distribution: Cliza (Cochabamba, 34km SE Cochabamba)
Sulcorebutia cochabambina Rausch: has pinkish to dark magenta flowers (occasionally with yellow throat) and clustering dull green bodies. Distribution: Arani, Cochabamba.
Sulcorebutia heinzii Halda, Heřtus & Horáček: has very dark mauve-blue body, pectinated spines and shining deep magenta flowers, in age forms clusters or cushions. Distribution: Siles, (Road Totora-Omereque) Cochabamba.
Sulcorebutia krahnii Rausch: has bright yellow flowers. Spination variable in colour and thickness usually yellow and brown. Distribution: Cerro Tukiphalla (North-West of Comarapa), Santa Cruz, Bolivia
Sulcorebutia mizquensis Rausch: has dark green stems, white or brownish pectinated spines, pointing diagonally and downward. Flowers pink-violet or magenta. Distribution: near Mizque, Cochabamba.
Sulcorebutia pampagrandensis Rausch: has grey-green body, long narrow yellowish areoles and mostly yellowish pectinate spines. The blooms are mauve. Distribution: Cochabamba, (Epizana, Mizque, Aiquile, South of Totora)
Sulcorebutia steinbachii f. bicolorispina Gertel: Silver and black spines, hence the name. Purple flowers.
Sulcorebutia steinbachii var. horrida Rausch: has strong dark brown protruding spines and tanned green or bluish-black bodies. Readily forms clusters or cushions up to 30 cm (or more) in diameter. Distribution: Vacas, Cochabamba.
Sulcorebutia steinbachii subs. markusii (Rausch) Gertel & J.de Vries
Sulcorebutia taratensis var. minima Rausch: has minuscule bodies which cluster like a mad, readily forming crowded mounds or cushions with hundred of heads. The flowers are bright purple. Anzaldo to Sacabamba, Cochabamba, Bolivia.

Notes: Sulcorebutia steinbachiiSN|31363]]SN|5220]] is one of the most variable cactus species. The colour of the flower, the spines length, the body shape and pigmentation is extremely variable, even within a population. There are also many localized phenotypes capable of maintaining their separate identity, even though only a few kilometers apart and by former authors considered as separated species and varieties. They are nowadays considered just phenotypes of a highly polymorphic specie. These subpopulations are not only morphologically based but also geographically and can be grouped as follow:

Group 1a: Cochabamba to Chapare, northward and eastward to Tiraque
