  Turbinicarpus schmiedickeanus
ssp. gracilis
CACTUSPEDIA       

 


The Latin epithet "gracilis" means "slender", referring to the slender spines and tubercles.
 


Turbinicarpus schmiedickeanus
ssp. gracilis (Aramberry, NL. Mexico)

Description: This species typically will grow solitary but may on occasion cluster, it is very similar to T. schmiedickeanus ssp. dickisoniae  the closest variety from which differ in type and number of spines.
Stem: The stem is globular and depressed, up to 30mm high 30-40mm wide grey-green (but in cultivated plants it can be more elongated and wide). 
Tubercles:  round. ca. 7 mm long (compared to the 3-5 mm long tubercles of ssp. dickisoniae), ca. 1.8 mm in diameter at tip, 3-5 mm broad at base, slender, nearly terete, somewhat angled, bright greyish green;
Central spines Thin and papyraceous ca. 18-23 mm long, 1 mm wide, grey, erect but flexible and curved;
Radials spines:
few short, 2 mm long, white deflexed in lower portion of areole, perpendicular to axis of tubercle; occasionally present also in adult specimens but deciduous.
Flower:
Slender funnelshaped, 2 cm long, 1,5 cm in diameter; outer perianth segments white with pale greenish brown to narrow greenish or cerise mid-line; inner segments pure white;
Fruit:
 Tan, globose, dehiscent along longitudinal slit;
Seeds:
 Small, black, finely tuberculate, ca. 1 mm long, 0.5 mm in diameter.

Cultivation: 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.
