The leaves, up to 2 m long, are composed of lanceolate leaflets, with margins endowed with small spines, 12–15 cm long and arranged on the rachis in the opposite way to 135°.
It is a dioecious species, endowed with ovoid male cones, sessile, yellow in color, 29–38 cm long and 14–18 cm broad, with broad and rhombic microsporophylls. The female cones have a yellow-green color, are 35–40 cm long and 20–23 cm broad, with macrosporophylls with a warty surface.
The seeds have an oblong shape, are 25–30 mm long and are covered with a red flesh.[2]
