Description: Turbinicarpus schmiedickeanusSN|12688]]SN|12648]] subs. schwarzii best known as: Turbinicarpus schwarziiSN|12648]]SN|34222]] is a one of the several local form of the very variable Turbinicarpus schmiedickeanusSN|34222]]SN|12648]] distinguished for having flattened tubercles with yellow-grey central spines and ivory white flowers in spring. This subspecies exhibits wide diversity in form.
Habit: It is a solitary or slowly clumping, small cactus, dichotomy also observed.
Stem: Flattened semi-globose, turbinate, pale green. In habitat rarely exceding 2 cm of height and 3,5-5 cm in diameter with a further 30 mm underground, but often much more larger in cultivation.
Parastichy number: 5 and 8.
Areoles: Oval, woolly, at top of plant, quickly disappear.
Tubercles: Flattened 4-angled (diamond shaped) broad and stumpy,
Spines: 1 to 3 spongy yellow-grey, yellowish-brown or whitish horn coloured (Newly emerged centrals yellow-brown), the lower one longer, up to 2 cm, the 2 side spine approximately 4-5 mm, often missing, still shorter, flattened below, curved towards the apex and often contorted grey, corky, rather soft, with transverse fissures. The spines are bunched at plant apex and persistent only on the upper body, below they fall off and the body and tubercles are corky and bare. Juvenile radial spines are feathery and very characteristic.
Root: Tap root, nearly shaped like a drawn molar tooth, with mass of fibrous roots.
Flowers: Apical short tubed, campanulate, 20-30 mm long, 30-40 mm wide, sepals lanceolate, margins entire, white or (rarely) pink.
Flowering season: Early spring (Jan-April) flowering.
NOTE: For a long time it was thought that Turbinicarpus polaskiiSN|12648]]SN|12688]] was a synonym of this taxa. The easiest ways to distinguish between them are: schwarzii has a pale green epidermis, angled tubercles and white stigma, whereas polaskii has a brownish epidermis, flat, rounded tubercles and pink stigma.

Cultivation and Propagation: It’s a fairly easy species to cultivate. Need a very well drained soil. Requires strong sun to part sun to develop good spinal growth and waterings should be rather infrequent to keep the plant compact and not to become excessively elongated and unnatural in appearance. keep dry in winter or when night temperatures remain below 10° C, it is hardy to -4°C for a short period. Assure a good ventilation.
