This plant has an erect or decombent stem, with a diameter of 25-30 cm and a height of 2.5 meters.

The leaves, pinnate, irregularly twisted on themselves and 80-120 cm long, are composed of numerous pairs of lanceolate leaflets, with a leathery consistency, arranged on the rachis in the opposite way, with an angle of 45°. The base of the petiole is tomentose on the dorsal and glabrous side on the ventral side.

It is a dioecious species, of which only male specimens have been described in nature. Their cones, from 1 to 6, erect, pedunculated, coarsely cylindrical, are about 30 cm long and 6–7 cm in diameter.[2]
