Pediocactus bradyi

This photograph was taken in Marble Canyon, at one of the better known locations of this tiny cactus. The crack-open seed pod is full of large seeds, about the same size as Astrophytum seeds.
The small plants look very similar to juvenile Pediocactus simpsony plants, neat and tidy.

Mammillaria heyderi grows near Douglas, AZ, on volcanic soil. The plants in this area are very flat, most often level with the ground, unless found in shady area. This is a good example of a natural look to be desired for this species in horticulture.
