Cylindropuntia acanthocarpa var. acanthocarpa

Donald J. Pinkava
Treatment appears in FNA Volume 4. Treatment on page 117. Mentioned on page 116.

Shrubs or small trees, with few branches, usually at acute angles. Stem segments green, 6–17.5 cm; tubercles broad, rounded, oval, 1.5–2.2 cm. Spines 15–25 per areole, brown, aging gray, not baggy sheathed; major 5–7 abaxial spines deflexed, subparallel. Flowers: inner tepals yellow-green, sometimes reddish orange tinged. Fruits densely spiny; areoles 16–26.


Phenology: Flowering spring (May).
Habitat: Mojave Desert, edges of juniper woodlands, rocky slopes
Elevation: 1100-1200 m
