Notes for the Genus:

Geohintonia

Etymology -Named in honor of its discoverer George S. Hinton.
Geohintonia is a genus of just a single species. It is a very distinct in appearance – quite unlike any other cacti. The body of these plants are globose to somewhat columnar when older. The have around 20 very prominent ribs with flat sides that looking almost like cooling fins on a circular radiator. The body color of the plants is a frosty, blue-grey. The edges of the ribs are dotted with white areole bearing flexible short spines at the top of the plant and scars where areoles later fall off further down the ribs. Flowers come from the wooly apex and are dark pink, funnelform with yellow stamens and a white stigma.

In the wild, Geohintonia is found in only one location in Nuevo Leon where it grows on steep cliffs of pure gypsum. The popularity of this plant and limited natural range has lead to illegal collecting of plants which poses a serious threat to their survival. This wild collection is quite unnecessary as the plant has been widely cultivated by seed since its discovery in 1991 and the process sped up considerably through grafting.
