Ariocarpus fissuratus ssp. bravoanus

 

This is a gem of a cactus, heavily over-collected - probably extinct in the wild. The flowers are magnificent for such a small plant. These, of course, are seed grown and it has only been in recent years that nursery grown plants have become available. Accidentally discovered by Hector Hernández in 1991 in the Municipio Guadalcazar, south of Entronque Huizache in San Luis Potosí, it was named in honor of Dra Helia Bravo.
