Sulcorebutia steinbachii veronikae

Description: Rebutia steinbachii is a clumping plant (rarely solitary), readily forming, especially in cultivation, clumps of many heads. 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. However it is very variable due to it's wide area of origin in Bolivia and spines ranges in colour from white, to yellow, red, brown or black.
Stem: 24-40 mm tall, up to 50 mm wide, flattened globose, greysh-green to dark green sometime tinged red.
Ribs: Approx 13, spiralling, poorly distinguished, forming oblong rhomboidal grooved tubercles.
Areoles: Long narrow depressed with short grey felt (almost naked) 3 – 6 long, 1,5-2 mm large.
Radial spines: 9-12 (or more) about up to 20 mm long, acicular, addpressed against the body, ± pectinate to porrect, white, yellow, brown with darker tips or almost black, ± curved slow to develops, frequently absent on new areoles at plant apex.
Central spines: None or usually 1 to 3, 10-30 mm long, only slightly stouter of the same colour of the radials.
Flowers: Arising from monoflorous areoles, in lower lateral flower zone. Rarely more than 3,5 cm long and 4,5 in diameter, yellow, red, magenta, violet or orange often with white inner petals. Floral tube funnel-shaped, with broad naked scales.

Rebutia steinbachii - garden

Origin and Habitat: North and east of Cochabamba in the Cordillera de Cochabamba, in southern Bolivia. Sulcorebutia is the type species of the genus Sulcorebutia. The first plants were collected near Colomi, along the route from Cochabamba to Chapare, by a Herr Steinbach.
Altitude range: 2900-3800 metres above sea level.
Habitat: Grows mainly on a flat, dry, stony area along the banks of the Rio Lopez, just before the moister zone of the tiraquensis populations.

Notes: Sulcorebutia steinbachii 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
Sulcorebutia glomerispina
- S. tuberculato-chrysantha
- S. polymorpha
- S. kruegeri
- S. hoffmanniana
- S. glanduliflora Card. n.n.
- S. cochabambina
- S. steinbachii & vars. australis, gracilior, etc.
Group 1b: Province Tiraque to Epizana an eastward to Comarapa, 2,800 m-3.000 m.
Sulcorebutia tiraquensis & vars. longiseta
- S. spinosior & aglaia (bicolorispina)
- S. lepida
- S. krahnii
Group 2: Cerro Tunari-south and east of Cochabamba-Izata to Anzaldo, 3,400-3,900 m
Sulcorebutia verticillacantha
- S. tunariensis
- S. taratensis & var. minima

Group 4: Around Totora and southward toward Epizana, 2,600-3,000 m

Rebutia steinbachii - garden

Accepted Scientific Name: Rebutia steinbachii Werderm.
Notizbl. Bot. Gart. Berlin-Dahlem 11: 268. 1931

Origin and Habitat: Garden origin (Nursery produced cultivar)

Description: Rebutia steinbachii often listed under its old name of Sulcorebutia steinbachii is a clumping plant (rarely solitary), readily forming, especially in cultivation, clumps of many heads. 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. However it is very variable due to it's wide area of origin in Bolivia and spines ranges in colour from white, to yellow, red, brown or black. There are several different subspecies and cultivars.
Crested form: The crested form (Rebutia steinbachii f. cristata) is very rare and sought after by collectors, for its unique features. It is a small low growing crested cactus that will slowly forms tangled groups up to 30 cm (or more ) in diameter with age. The plant tends to grow seated in substrate, but in cultivation it is almost always seen grafted on columnar cacti. There are several crested clones often very different one to each other.
Stem: Greysh-green to dark green sometime tinged red.
Ribs: Poorly distinguished, forming oblong rhomboidal grooved tubercles.
Areoles: Long narrow depressed with short grey felt (almost naked) 3 – 6 long, 1,5-2 mm large.
Radial spines: 9-12 (or more) about up to 20 mm long, acicular, addpressed against the body, ± pectinate to porrect, white, yellow, brown with darker tips or almost black, ± curved slow to develops, frequently absent on new areoles at plant apex.
Central spines: None or usually 1 to 3, 10-30 mm long, only slightly stouter of the same colour of the radials.
Flowers: Arising from monoflorous areoles, in lower lateral flower zone. Rarely more than 3,5 cm long and 4,5 in diameter, yellow, red, magenta or orange with white inner petals. Floral tube funnel-shaped, with broad naked scales.
Phenology: Blossoming time late spring.
Fruits: Small papery olive green to reddish brown at maturity.
Seeds: Black.

Cultivation and Propagation: It 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 and an appropriate air circulation.
Watering Needs: Water moderately in the growing season, keep dry during the winter rest.
Frost Tolerance: Plants are quite frost hardy -5 (-10)° C, but for safe cultivation overwinter in a cool place (at 0/10°C) this is important for the flowers as well as for plants health. Without this cool winter period they normally wont get any buds.
Sun Exposure: Needs a full sun exposure ( light shadow my be useful in the hottest summer days).
Propagation: Cutting, grafting.
