Form & Character: Stout, fixed, rigid, arborescent, friendly looking, but DON'T GET TOO CLOSE as you likely will be wearing stems segments on your pants or self.

Branches are not truly cylindrical but have raised areas called tubercles on which the spine-bearing areoles are located. Definitely coarse textured.

Flowers & fruits: Flowers greenish yellow to 1.5 inches across, fruit deciduous, fleshy, the upper tubercles larger than the lower.

Recently, the genus Opunita was taxonomically re-organized. Many references will never-the-less still incorrectly refer to chollas as belonging to the genus Opuntia, rather than Cylindropuntia.
