Abstract

Ariocarpus fissuratus var. hintonii W. Stuppy & N.P. Taylor, from northern San Luis Potosí, Mexico, is described and compared with var. fissuratus. It differs from other forms of the species by its dwarf stem, narrower tubercles, smaller seeds and disjunct distribution. A. fissuratus var. lloydii is linked to var. fissuratus by populations intermediate in character. A key to the three varieties of A. fissuratus is provided.
