On Oct 1, 2004, Xenomorf from Valley of the Sun, AZ (Zone 9b) wrote:

Some comparisons between three Hedgehog species that were at one time considered to be three varieties of Echinocereus fasciculatus.
E. fasciculatus has grayish central spines that are 1-3 inches long.
E. boyce-thompsonii has straw (yellow-tan) colored central spines that are 1-4 inches long.
E. bonkerae has shorter (half inch) central spines that are grayish-white.

Other synonyms are: Mammillaria fasciculata, Echinocereus fendleri var. fasciculatus, Echinocereus engelmannii subsp. fasciculatus, Echinocereus fendleri var. robustus, Echinocereus abbeae, Echinocereus abbae

I've seen this growing in the wild near Oracle, Oro Valley & Tucson AZ.
