Description: Usually solitary or sometime forming clumps after a few
years. This species has a wide range and shows a great variability ether

greys-bluish-green, apex rounded woolly.
Roots: Central thin tap-root.
Tubercles: In 8-13 series, rhomboid, up to 10 mm tall, delineated by a
groove near the areole on the upper surface, axil woolly,
Areoles: Round, approx 7 mm in diameter slightly woolly,.
Radial spines: 9-15(-20), thick, subulated, 10-20 long, radiating
sideways and downward, straight or somewhat curving, grey or whitish.
Central spines: Mostly 3-4 central spines of which the dominant one
(sometime absent), straight, subulated or partially recurving, 2- 3 cm

Nowadays regarded as:
Coryphantha delaetiana (Quehl) Berger 1929
Origin: Mexican states of Chihuahua,

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

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
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.
Cultivation: Small growing and easy to to
cactus compost and very willing to flower,
Because of it’s small size makes a great potted plant specimen,
great for beginning collectors, water sparingly and allow to dry between
watering, needs good drainage. Watering should be curtailed during the winter months. Full
sun but is tolerant and prefers light shade during the hot Summer
provide very good
ventilation. Frost Tolerance: Hardy to - 5°C if kept dry.
Propagation: Seeds (usually) or by the
shoots of adult plants (if available).
