Opuntialaevis is a sometimes spineless prickly pear cactus that grows in various locations in southern AZ but particularly on canyon walls or in the rubble below rather than canyon floors.
O.laevis plants are naturally spineless, or they may have a few short spines at the tips of cladodes or along the surface, but just a few. Cladodes on this prickly pear may be large, up to 10-12 cm wide and 30 cm long. They are often narrow proximally or may be elliptical, long-obovate, or sometimes obovate. Areoles are small, 3-4 mm long. Leaves are modestly recurved.
Flowers are yellow and tinged with red, about 6 cm broad. Stigmas are slender. The fruit is pyriform, 5-6(8) cm long and deeply umbilicate. The seeds are irregular and about 5 mm in diameter with a thick, undulate margin.
