Acanthocereus tetragonus

Acanthocereus tetragonus is a striking member of the cactus family (Cactaceae). Commonly known as "Triangle Cactus" or "Barbed Wire Cactus," this plant is recognized by its long, erect or scrambling, three to five angled, green stems. The stems are bright green when young, becoming darker and more woody as they mature. This cactus derives its name from the fact that its stem cross section is frequently triangular.
