Ariocarpus fissuratus 'intermedius', a typical specimen in habitat.

Comments

Plants of Ariocarpus fissuratus from Cuatrocienagas are typical of what was described by Backeberg as A. intermedius, the plants are larger than the more northerly form, but do not achieve the sizes achieved still further south, where this form is replaced by the larger, smoother ''lloydii' type plant.
