Strombocactus disciformis ssp. esperanzae
Date: 1996 October 30
Location: Guanajuato
This subspecies of Strombocactus was described by Glass and S. Arias, in
the British Cactus & Succulent Journal, Volume 14, No. 4, December
1996. Its most distinctive difference from ssp. disciformis is
the deep magenta flower (pictured in the journal). It is named for
Sra. Esperanza Benavides de Valásquez, a local community leader,
who helped by locating plants in flower accessible
enough to be photographed.
It is pictured below (left) growing with Turbinicarpus alonsoi (right).
