Pachycereus pringlei also known as Mexican giant cardon or elephant cactus
Morphology[edit]
A cardon specimen is the tallest[1] living cactus in the world, with a maximum recorded height of 19.2 m (63 ft 0 in), with a stout trunk up to 1 m (3 ft 3 in) in diameter bearing several erect branches. In overall appearance, it resembles the related saguaro (Carnegiea gigantea), but differs in being more heavily branched and having branching nearer the base of the stem, fewer ribs on the stems, blossoms located lower along the stem, differences in areoles and spination, and spinier fruit.
Its flowers are white, large, nocturnal, and appear along the ribs as opposed to only apices of the stems.
