J20160627-0016—Echinocereus apachensis

Echinocereus cf apachensis. I use "cf" because I am unsure of my identification. That puts me in league with authors of taxonomical treatments who seem uncertain whether the taxon exists. See Flora of North America: www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=2... for example. Photographed in a private garden in Berkeley, CA.
