Family:
Cactaceae (Cactus
Family)
Scientific name: Coryphantha difficilis (Quehl) A.Berger
1929
Synonyms:
- Mammillaria difficilis Quehl 1908.
- Coryphantha densispina Werdermann in Fedde 1932
Origin: Grows in the Mexican state of Coahuila
Growth Habits:
Solitary,
spherical to short
cylindrical bluish-Gray green
stems up to 8 cm tall , 6 cm in diameter.
The
tubercles are oblique and their outer end points outwards; 4
central spines, to 3 cm long; 12 to 14
radial spines, up to 2 cm long ( Similarly to Coryphantha
salinensis two types of
radial spines can be differentiated: lower, stiff, regularly
radiating, often only 10 mm long spines and upper, longer (up to 20 mm)
often bundled spines.)
The
flowers are large purely yellow, without any red in the
throat.
Cultivation:
In
culture, contrary to its name "difficilis" (difficult) this
species does not show special problems, but it is very
slow-growing. In C.difficilis the observation of the plant
development from
radial spined
youth-forms to the definite, wildly spined outlook is particularly
interesting.
