Obovate cladodes 14cm+ long and up 8.5 cm at widest point, lacking spines lower 1/3rd of pad, pads not easily detached, areoles mostly 2 cm apart, lateral central spines declined, erect to spreading distally, nor barbed. Receptacles/fruits narrow, elongated, typically at least 4 to 5 cm long, constricted at base, mostly spineless with rarely very short to short spines. Fruits growing solely on distal end of pad, from to 1 to 6+ per pad.
Growing two feet east of a hybrid O. fragilis x O. macrorhiza plant (see #626), near oak canopy and near more O. macrorhiza plants growing in partial shade. The hybrid plants (see #626) were in turn growing just to the east of clump forming non-introgressed O. fragilis which was in turn growing in front of area typical O. macrorhiza which continued to form larger stands to the west in the small enclosed natural spaces that is surrounded by private residences. The three different forms of cacti are growing here primarily in the northern portion of the opening along the edge of the Gambel's oaks with first an understory of Berberis repens, Ribes aureum and Elymus glaucus, and then in close proximity to Rhus trilobata.
