Pachycereus marginatus is a species of plant in the Cactaceae family. (Also sometimes called "Mexican Fencepost Cactus".[1]) It has columnar trunks that grow slowly to 12 feet (3.7m) and may reach 20 feet (6.1m) in height. Stems are 3 to 4 inches (9–10 cm) in diameter; ribs 5 to 7 inches (13–18 cm). Its central spine is about 3/8 inch (1 cm) in diameter with 5-9 radials and slightly yellowish in colour. Its cuttings are sometimes used to create fences as its spines are not as large or dangerous as some cacti.[1]
