Family: Cactaceae (Cactus Family)


Scientific name:  Sclerocactus wetlandicus Hochstätter ssp. wetlandicus
Published in: Succulenta (Netherlands). 68: 123, figs. s.n. (upper row, p. 124). 1989.

Conservation status: Listed in CITES appendix 1.

Common Names include:

  • Uinta basin hookless cactus

Sclerocactus wetlandicus is morphologically very similar to S. glaucus and has been frequently treated within S. glaucous, but the two populations are geographically separated and Phylogenetic analyses of chloroplast DNA are ambiguous regarding the closest relative of S. wetlandicus.  However, this species is related to S. brevispinus, S. glaucus, S. wrightiae, S. whipplei, and S. parviflorus. We refer to this species as the Sclerocactus glaucus complex.

Synonyms:  
  • Pediocactus wetlandicus (Hochstätter) Halda
  • Sclerocactus glaucus
  • Sclerocactus glaucus ssp. wetlandicus

Origin: Duchesne and Uintah counties, Utah.
Habitat:  Gravel-covered clay hills, desert grasslands, saltbush, rabbit brush flats; of conservation concern; 1300-1500 m.


 

 



Cultivation:
 This plant is very rare in cultivation; it does not do well.  It is very difficult to grow its own roots.  Mature individuals easily rot and die, especially after planting. 
It is extremely xerophytic and adapted to very dry soils, but plant grafted an hardy Opuntia compressa stock are very easy to grow and no special skill is required, they can stay in a non heated green house or outdoors in raised beds, terraces, window sills etc..
This cactus continue
s to be, a particular prize among collectors.

Propagation: Seeds are extremely difficult to germinate  (only 2-3 percent of seeds germinate) The germination is really difficult and if some seedling finally sprout, as they start to grows they disappear one by oneGrafting is often used to speed growth rate and to create a back-up for plants in collection.
