Location: Valley of Rayones, Nuevo Leon

Ariocarpus scaphirostris LRM64, a large specimen growing in the Valley of Rayones.

Comments

Ariocarpus scaphirostris is very limited in distribution, occurring on fragile shale slopes in the Valley of Rayones. The major threat to the plants in habitat apart from collecting comes from goats, which can severely damage the shale formations on which the plants occur by trampling.
