among the the most wide-spread of the Parodia species and are
very variable in appearance. The P. mammulosa
complex
comprises lots of names and lots of different

arrangement of the spines, stems, ribs and flowers colour with unclear

There are a
number of variety and forms of this highly variable cactus species, but
not all are universally recognized. Some authorities recognize the
following varieties:
Parodia mammullosa ssp. mammulosa
Plants have 18-25 ribs, 2-4 central spines and 20-30 radials It is
widely distributed in Brazil, Uruguay and Argentina.
Parodia mammullosa ssp. brasilensis They have about 15
ribs, 1 central spine, 8-10 radials, it occur near Santos, Brasil.
Parodia mammullosa ssp. erythracantha They have about 16
ribs, 2 central spines and 10-14 radials it occour in Tacuarembo,
Uruguay.
Parodia mammullosa ssp. submammullosa
These plants have the fewest number of ribs (about 13), about 6 radial
spines spreading out horizontally, and two long and flat central spines,
of which one longer and pointing down, and another a bit shorter and
pointing up, with a slender groove along their lower part. Spines are
yellow with a brown tip, the largest having a red base when young, later
turning gray.). It occours in Uruguai and argentina..
Cultivation:
This is an easy plant to cultivate. It
require a
mineral-based potting mix with a good
drainage.
Can support quite some water during the growing season
but pot plants in winter are
wet-sensitive and
needs to be kept
dry (rots easily if soil is wet and cold).
Usually it is recommended to
over-winter
this plant in a bright and warm greenhouse with at least 8-10° C ,
but it has
proved to tolerate temperatures as low
as -5° C for short periods.
Sun Exposure:
Light shade to
full sun but doesn't like
full, hot blazing sun in the central summer month.
Propagation: Seeds,
cuttings. Not too difficult to raise from seed.
