It is an evergreen perennial growing to 15 feet 6 inches (4.72 m) with a noticeable expanded caudex, for storing water. The single palm-like stem produces terminal tufts of strap-shaped, recurved leathery leaves, sometimes hair lock-shaped in the ends, and with occasional panicles of small white flowers once the plant reaches over 10 years of age. The only moderately swollen trunk at the base is slender over it and only slightly branched. The almost spherical caudex in the youth stage later becomes 4 to 6 meters long and reaches a diameter of up to 50 centimeters and more at the base. The bark is smooth. The green lineal, slightly rejuvenated and bent leaves are thin, flat or slightly ridged. They are 90 to 180 inches long and 15 to 20 millimeters wide.
