description
Pachycereus lepidanthus grows tree-shaped with single or a few columnar, light green shoots branching from the base and reaches heights of 3 to 4 meters with diameters of up to 8 centimeters. There are seven to nine low ribs, triangular in cross-section . The initially yellowish spines turn gray later and are difficult to distinguish between central and radial spines. The three central spines are up to 6 inches long. The upper central spines are directed upwards, the lower slightly downwards. The roughly ten stiff radial spines are 1.5 centimeters long.
The funnel-shaped, yellow to yellowish orange flowers appear from older areoles near the shoot tips. They are up to 7 centimeters long and have a diameter of 2.5 centimeters. Your pericarpel and the flower tube are densely covered with membranous, leaf-like scales. The fruits are dry.
