description
Pilosocereus goianus grows shrubby, branches at the base or forms a short trunk, is then candelabra-like and reaches heights of growth of up to 2.8 meters. The upright or basal upwardly curved greyish green shoots have a diameter of 6.5 to 11 centimeters. There are 13 to 15 low ribs. The initially light felted areoles are later dark gray. They are 6 to 11 millimeters apart. The 26 to 40 thorns are needle-like and piercing. The 12 to 16 protruding central spines are in two slightly different rows. The outer thorns are up to 2.1 inches long, the inner ones are stronger and up to 3.4 inches long. The up to 30 radial spines are very different in length (1.5–13 millimeters). The flowering areoles are scattered on the shoots. A tuft of light, loosely colored hair up to 2.6 centimeters long emerges from them and later turns silver-gray.
The bell-shaped to funnel-shaped flowers are up to 4.8 centimeters long and reach a diameter of 3 centimeters. The flower tube is brown, the bracts are white. The flattened, spherical, wrinkled fruits are greenish to brown or dark red. They have a diameter of up to 4.2 centimeters and are up to 3.2 centimeters high. The fruits contain a dark pink pulp.
