scaphirostris, frequently the last
species of the genus to bloom.
gray-green, rising barely above ground level, subglobose or
globose, more or less rounded on top, 2-6cm high, 3-7cm in diam.;
tubercles divergent, erect, not crowded or basally compressed,
bluntly pointed at the apices, flattened and smooth adaxially,
fissured, slightly incurved, 2-4cm long, 5-8 mm broad, at least
twice as long as wide; spine-bearing portions of the areoles absent
at the tips of the tubercles; flowers 3-4cm in diam., magenta;
fruit greenish, 9-15mm long 4-8mm in diam.
Originally described by Bodeker in 1930 this
species is extremely restricted in distribution in the wild,
populations occurring within a single valley in the state of Nuevo
Leon, where the plant occurs on extremely arid low limestone hills
in clayey soils. The original spelling of the name as A. scapharostrus
was corrected to A. scaphirostris by Hunt in 1992.
Ariocarpus scaphirostris is one of
the more difficult species of the genus in cultivation, it requires
a hot sunny position, and a well drained mineral compost, Plants
are small growing and will start to bloom at about 2.5 cm diameter,
grafting will greatly accelerate the growth rate, and flowers can
then be expected within 2-3 years from sowing. A variety of
A.scapharostrus var. swobodae has recently been published,
this awaits further evaluation, but is likely to fall within the
natural variation of the species.

collector data can be found on our field
