description
Neobuxbaumia polylopha grows individually and reaches heights of up to 13 meters. The columnar shoots are initially light green and become darker with age. They have a diameter of up to 50 centimeters. The 22 to 36 (rarely from 10) narrow, slightly curved ribs are separated from each other by a sharp furrow. The single, flexible central spine , which can also be missing, is often shorter than the seven to eight radial spines. The radial spines are also flexible and 1 to 2 inches long. They are yellowish to brownish and gray with age.
The flowers usually appear in groups near the shoot tips. They are dark red, 4 to 6 inches long and 3 to 3.5 inches in diameter. Your pericarpel and the flower tube are covered with fairly large humps and small scales, which are bare in the axillae. The egg-shaped, green fruits are 2.4 to 4 centimeters long and covered with scales, wool and bristles.
