Family: Cactaceae (Cactus Family)

Scientific name:  Coryphantha salm-dyckiana (Scheer) Britton & Rose
In: Cactaceae: 4: 28, 1923 nom. rejic.

Nowadays regarded as: Coryphantha delaetiana (Quehl) Berger 1929

Origin: Mexican states of Chihuahua, Durango and Coahuila.

Habitat: Often found in arid plains with sandy-gypsum or gravely soil.

Synonyms:

  • Mammillaria delaetiana Quehl 1908.
  • Mammillaria salm-dyckiana Scheer
    In: Salm-Diyck, Cact. Hort. Dyck. 1849:134, 1850 nom. rejic. (Dicht. 2000)
  • Echinocactus salm-dyckianus Poselger
    In: Allg. Gartenz. 21:102 1853 nom. rejic.
  • Cactus salm-dyckianus Kuntze
    In: Rev. Gen. Pl. 1:261, 1891 nom. rejic.

Notes: There is a long nomenclatural debate around this controversial species. The early description of Mammillaria salm-dyckiana by Scheer ( In: Salm-Diyck, Cact. Hort. Dyck. 1849:134, 1850) depicted a different plant with very large tubercles and only 8-10 radials and only one central spine, but this description correspond to the description of C. poselgeriana Dietrich 1851, the later combination Coryphantha salm-dickiana by Britton & Rose (In: Cactaceae: 4: 28, 1923) correspond to a plant with small tubercles, 15 radial spines, 1-4 central spines and correspond to the description of C. delaetiana (Quell 1908) Berger 1929.
Since the name name of Coryphantha salm-dyckiana has continuously used in its incorrect sense its name has been rejected by the committee for spermatophytes in 2000.
