description
Pilosocereus gounellei grows shrubby and rarely tree-shaped, branches out in large numbers from one trunk and reaches heights of 0.5 to 4 meters. The upright shoots become crooked or even horizontal with age. They are olive green, sometimes glaucous, and have a diameter of 3.7 to 9 centimeters. Young shoots appear near the tip of the main shoot. There are 8 to 15 ribs with transverse furrows. The opaque to translucent thorns are golden to reddish or brown or gray. The 1 to 10 ascending to protruding central spines are 1 to 13 centimeters (rarely up to 16 centimeters) long. The spread out 10 to 20 radial spines lie on the surface of the shoots and are 6 to 30 millimeters long. The flowering part of the shoots is weak to strong and is located near the tip of the shoot. The flower buds are completely surrounded by long, silky hair.
The funnel-shaped white flowers are 4 to 9 centimeters long and 2.5 to 6 centimeters in diameter. The spherical to depressed spherical fruits have a diameter of 4.5 to 6 centimeters, tear at their base or near the tip, and contain a magenta or white pulp.
