Original Publication

Ariocarpus scaphirostris

A. scaphirostris, frequently the last species of the genus to bloom.




Plant 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. 


Distribution (Map)

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 the species, A.scapharostrus var. swobodae has recently been published, this awaits further evaluation, but is likely to fall within the natural variation of the species.
