Ribs: Tuberculate.
Areoles: To 2-8 mm apart;
Radial spines: Usually 8, white to yellowish, basally brown; up to 1 cm long.

Subspecies, varieties, forms and cultivars of plants belonging to the Stenocactus crispatus group-complex
Stenocactus anfractuosus (Mart. ex Pfeiff.) A.Berger: ( Stenocactus crispatus ? ) The plant found in cultivation are quite variable, and the dissimilarity among seedlings spination may be considerable.- Stenocactus arrigens (Link ex A.Dietr.) A.Berger: The ribs are thin with very undulated or curled ridges. The plant found in cultivation are quite variable (same as Stenocactus crispatus)
- Stenocactus arrigens f. cristatus hort.: Crested form.
- Stenocactus confusus (Britton & Rose) F.M.Knuth in Backeb. & F.M.Knuth
- Stenocactus crispatus (DC.) A.Berger: It is a solitary plant closely covered with long spines and wavy ribs. This is a very variable species that now includes many form (previously considered independent species) with one form intergrading into another, creating a taxonomig nightmare.
- Stenocactus crispatus f. cristatus hort.: crested form.
- Stenocactus dichroacanthus (Mart. ex Pfeiff.) A.Berger ex Backeb. & F.M.Knuth
- Stenocactus fasciculatus hort.: Branched (or solitary) plant, up to 20 cm tall, 10 cm wide with long spines and wavy ribs. Cultivated form.
- Stenocactus gladiatus (Link & Otto) A.Berger ex Backeb. & F.M.Knuth: This plant is characterized by large, wide and flat sword-shaped central spines.
- Stenocactus grandicornis (Lem.) A.Berger ex Backeb. & F.M.Knuth: has very long flattened central spines.
- Stenocactus guerraianus (Backeb.) nov. comb. ined.: Globular, to 20 cm broad, dark-green with woolly apex. Spine are flattened, ferocious-looking with one very long milk-white central spine directed upwards.
- Stenocactus guerraianus f. cristatus: The crested form deviate considerably from the typical form for having thinner and densely packaged spines, however the overall appearance depend on clones.
- Stenocactus hastatus (Hopffer ex K.Schum.) A.Berger: Solitary cactus with long rigid and sharp spines. The plants in cultivation are quite variable.
- Stenocactus kellerianus hort.: The upper spine spines are long flat and straight.
- Stenocactus lamellosus (A.Dietr.) A.Berger: Solitary plant crowded with long spines and many wavy ribs.
- Stenocactus longispinus hort.: has very long spines. Cultivated form.
- Stenocactus violaciflorus (Quehl) A.Berger: Up to 20 cm tall, 10 cm wide with very long spines and wavy ribs. The ribs are thin with very undulated or curled ridges. Flowers pink-violet.
- Stenocactus wippermannii (Muehlenpf.) A.Berger: Up to 15 cm highly with about 35 ribs, weakly wavy. Radial spines: up to 18-22, sharp, white. Central spines: 3 awl-like, 2-6 cm long, the upper one more or less flat pressed and weakly curved milky-white with almost blackish-brown base
- Stenocactus xiphacanthus (Miq.) hort., nov. comb. ined.: ( Stenocactus crispatus ? ) "xiphacanthus" is an unclear name applied to variuos Stenocactus in cultivation. This plants are characterized by flattened (Sword-shaped), ferocious-looking spines with one long central spine directed upwards.

Cultivation and Propagation: Although regarded as a choice and difficult plant is not too difficult in a greenhouse, although grows quite slowly. It is sometime seen as a grafted plant but grows very well on its own roots too.
Soil: Use mineral well permeable mineral soil with little organic matter (peat, humus).
Exposure: They need a good amount of light shade to full sun this help to keep the plants healthy, although slow growth.
Watering: Water sparingly from March till October (weekly during summertime, if the weather is sunny enough) , with a little fertilizer added. Less or no water during cold winter months, or when night temperatures remain below 10° to prevent root loss. It is sensitive to overwatering (rot prone).
Fertilization: Feeding may not be necessary at all if the compost is fresh then, feed in summer only if the plant hasn't been repotted recently. Do not feed the plants from September onwards as this can cause lush growth which can be fatal during the darker cold months.
Hardiness: Keep perfectly dry in winter at temperatures from 5 to 15 degrees centigrade. (but it is relatively cold resistant and hardy to -5° C, or possibly colder for short periods) In the rest period no high atmospheric humidity!! (Temperature Zone: USDA 9-11)
Propagation: Grafting or cuttings. Plants are usually grafted onto column-shaped cacti but proved to be able to produce their own roots if degrafted. Cuttings will root better in hot weather. Cuttings must be kept quite dry to root. Large crested piece must be placed on the soil surface without burying the plant base down in the soil.
