description

The relatively small, bush-like, upright or elongated species of the genus Arthrocereus are branched or not branched. The articulated, cylindrical shoots have 10 to 18 low and narrow ribs on which small areoles sit, from which many thin thorns arise.

The elongated, bell-shaped, wide-opening flowers appear near the tip of the shoot and open at night. The flower cup and the flower tube are covered with wool, hair-like thorns and a few pointed scales.

The spherical to pear-shaped fruits are green and have a white pulp. They are thin-walled, non-tearing and have scales and hair-like thorns. The crooked egg-shaped seeds are black.

The species of the genus Arthrocereus are common in western and southeastern Brazil .
