entirely covered by the mass of white feathery spines.

or somewhat elongate, without latex, spherical, 4- 7 cm high and in
diameter. Light green, but appearing white because of the dense spines.

The spines in this specie have very long hairs along the spine-axis
arranged as are the segments of a bird's feather and that furnish an
epidermal protection against the blasting sun of the desert.

Small, growing clustering species with inoffensive white feather-like
spines which cover the plant.
Cultivation: Needs regular water in summer, but
for best appearance keep water off of the spines. Do not let the soil
become too dry in winter, either. It does better with a good drained soil
mix since it is a rot prone species,
whose roots are
easily lost in pots that stay damp for any length of time. It
takes a couple of years to offset, but once it starts it can fill a 25cm
pot in just a few years. Propagation: Seeds, offsets (Cuttings root
quickly). Needs full sun or light shade in summer.
