Details

Cylindropuntia abyssi is only known from the area of Peach Springs, AZ (Anderson, 2001) and is sometimes called the Peach Springs Canyon cholla. It occurs on the limestone hills and limestone-derived flats of this area between 500 to 800 m. Little study has been conducted since this taxon was described. This species may be a hybrid involving C. bigelovii, which also occurs in the Peach Springs area and which it superficially resembles.

C. abyssi are small, openly branching shrubs to 1 m tall. The stems are 8 to 14 cm long by 1.8 to 2.5 cm wide. There are 10 to 15 white or yellowish spines per aerole, and the sheaths are white, silver, or pale yellowish. The flowers, filaments, and stigmas are greenish-yellow with cream styles. Fruits are yellow, dry, and mostly spineless. C.  abyssi is diploid (2n = 22).
