It is an arborescent species, with a stem up to 6 m tall, erect, sometimes decumbent or even hanging, of 40–60 cm of diameter.
The leaves, pinnate, arranged in a crown at the apex of the stem, are 100–130 cm long, silvery-green to bluish-green in color, with a 15–26 cm long petiole. They are formed by numerous lanceolate, opposite, 15–19 cm long and 13–20 mm wide leaves, with a leathery consistency, inserted on the rachis with an angle of 45°.
It is a dioecious species; the male specimens usually have 1 to 3 cones, sub-cylindrical, olive-green, 16–26 cm long and 8–10 cm in diameter; female ones have 1 to 3 cones, ovoid, 30–40 cm long, 20–25 cm in diameter.
