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, grayish-green to dark green sometime tinged red.
Ribs: Approx 13, spiraling, 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, addressed 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.
