size, number of branches, number of tubercles, number and colour of the
spines and for the size and colour of flowers:
Eriosyce odieri ssp. odieri
Eriosyce odieri ssp. krausii
Eriosyce odieri ssp. malleolata (var. malleolata y var. weisseri)
Eriosyce odieri ssp. glabrescens
Eriosyce odieri ssp. fulva
Eriosyce odiery var. monteamargensis Has longer and stouter
spines and a central spine.

It is possible to find very
different plant named "odieri". This plant is very root prone, needs good drainage.
Habitat: Big valley
and gully from 10 to 320 m of altitude, it grows on low costal
flats and slopes in stony and very draining soil in areas where very
little else grows. It's a very drought tolerant species. Despite the
lack of rain where it lives, the extreme aridity is
attenuated by the frequent, often dense, coastal fogs. The fog tends to
concentrate in the form of a cloud band
It shows a recurrent pattern; usually it
is overcast in the early
mornings, the clouds dissipating during the late morning and returning
during the late afternoons.
