Description
editCephalocereus mezcalaensis grows individually and reaches a height of 5 to 10 meters. The columnar, yellowish green shoots have a diameter of 13 to 40 centimeters. The 13 to 25 ribs are wide and angular. The one to four slightly flattened central spines are straight, dark and only slightly longer than the five to nine marginal spines. The expanded marginal spines are whitish to yellowish, darker at their tip and 0.8 to 2 centimeters long.
The funnel-shaped flowers often appear along the entire shoot. They are white to yellowish and purple and up to 5 centimeters long. Its pericarpel and flower tube are covered with tubercles with small scales and wool. The spherical to egg-shaped fruits are 3 to 4 centimeters long and covered with humps that carry perennial wool and thorns.[2]
