Cylindropuntia

Cylindropuntia bigelovii

Cylindropuntia is a genus of flowering plants of the cactus family ( Cactaceae ). The botanical name of the genus derives from the Greek noun " κύλινδρσς " ( cylindros ) for roll and refers to the cylindrical shape of the shoots.

Description

The species of the genus Cylindropuntia grow shrubby or tree-like. You are branched upright and strong. The cylindrical to slightly club-shaped drive sections are straight, clearly tuberculate, glabrous and of varying length. The differently shaped areoles bear glochids. The entire, papery spines have a vagina and fall off completely. The major spikes are flattened only at the base or not.

The flowers are yellow-green, yellow, bronze, red or magenta. The cylindrical to almost spherical, sometimes club-shaped fruits are fleshy or dry. You can be spined, are colored red to green to yellow and brown when they dry. The pale yellow to light brown, sometimes gray seeds are flattened and have a length or a diameter of 2.5 to 5 millimeters.

Systematics and distribution

The species of the genus Cylindropuntia are in the southwest and southern United States and widespread through southern Mexico to Mexico City. One species occurs in the Caribbean, another in South America.
