description
Pachycereus tepamo grows tree-shaped, has rich candelabra -shaped branches and reaches a height of 7 to 10 meters (rarely up to 12 meters). Trunks up to 1 meter high are formed. The bluish green, upright shoots branch out from their base. They have a diameter of about 20 centimeters. There are 8 to 9 (rarely 7 to 10) ribs . The elliptical, woolly areoles on it are 2.5 centimeters long. The resulting strong, stiff thorns are whitish gray and black both at their base and at their tip. The four, rarely five, central spines are polygonal in cross section and up to 4.5 centimeters long. Two of them face downward, one face upward, and one is protruding. The six to eleven flattened, stiff radial spines are 5 to 30 millimeters long.
Areoles capable of flowering are circular and covered with wool. From them arise 17 to 45, up to 6 centimeters long spines, which cannot be differentiated into central and radial spines. The funnel-shaped flowers appear near the shoot tips. They open at night and are 6 to 8 inches long. Your pericarpel is completely covered with yellow bristles. The flower tube, on the other hand, is covered with somewhat purple-colored scales with bare armpits. The spherical, fleshy, red-purple fruits are tear-open. Their areoles have a straw yellow wool and numerous bristles 3 centimeters long.
