This shows the complete stems of the kind of barrel cactus that doesn't seem to be the yellow-fruiting F. wislizeni.

An example of the small, low-growing mammillaria-type cactus with a tiny red fruit still on it.  Each stem was on the order of 1.5-2 inches in diameter, so the fruit was, at a guess, no more than 1/4 inch across.

If one looked carefully, there were a few other kinds of cactus growing in the yard besides saguaro, cholla, ocotillo, prickly pear, and the large fishhook barrel cactus.  One was a small cactus that grew in clusters.  It resembled a Mammillaria, and was covered in a network of intersecting fine needles, and further protected by projecting longer, thicker fishhook shaped spines.  Occasionally a few tiny cherry red fruits would be visible.

The nearly total absence of spines on the fruit of this cholla suggest it is staghorn rather than buckhorn cholla.
