Description: Sulcorebutia augustiniiSN|10860]]SN|10860]] is one of the innumerable local form of the very variable Rebutia steinbachiiSN|5221]]SN|5221]] (= SulcoSN'>5220' alt='5221'>Rebutia steinbachii#SN#5221'>Sulco[[Rebutia steinbachiiSN' style='border:none;'>) characterized by 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.
Note: Rebutia steinbachii subv. augustinii is apparently a neotenic variety of the species in which juvenile spination is retained throughout the life of the plant, while many of the other varieties are dimorphic (short spined juvenile forms transform at maturity to strongly spined forms).
Habit: It is a clumping plant, readily forming, especially in cultivation, dense clumps or cushion of many heads and flat to the ground.
Roots: Mostly non-succulent, fibrous roots. More than 90% of the plant is concentrated in the stem.
Stem: Single heads 30–40 mm wide (but often smaller), globular, flattened and somehow apically depressed, grey-green, almost hidden under the covering of spines.
Ribs: 12-26, spiralling, forming oblong rhomboid tubercles with well-defined grooves.
Tubercles: Conical conspicuous.
Areoles: White or yellowish, long, narrow 3-6 long, 1,5-2 mm large.
Spines: Tiny Amber coloured and pectinate, often more than 20. These spines obscure the stem giving the plant a straw-yellow to reddish-brown appearance.
Flowers: Bright pink to light purple, numerous in a ring at the base of the plant.
Blooming season: Spring (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.

Cultivation and Propagation: These mountainous plants have thick taproots and are susceptible to overwatering. They loves a very permeable, coarse mineral soil as well as to be strictly kept dry throughout the winter quiescent period since it is very sensitive to any moisture excesses, To prevent rottenness it is also advisable to surround its root neck by very rough sand or grit, this help a fast water drainage. They requires also an appropriate air circulation and are sometime grafted to avoid root problems. They need to be kept in a cool place during winter rest (at 0-10°C). This is important for the flowers, as well as for their health. Without this cool winter period, they normally won't get any buds.
Grafted plants are very easy to grow. Needs a full sun exposure ( light shadow my be useful in the hottest summer days).
Propagation: Seed, cutting, grafting
