This cycad has an underground stem, up to 25 cm high and 20-30 cm in diameter, often with secondary stems from shoots at its base. Its pinnate leaves are erect, 80–120 cm long, and form a crown atop the stem, supported by 2 cm long petioles. Each leaf has 48-58 pairs of lanceolate leaflets with spiny green glaucous margins, angled at 70-75° on the rachis. It is dioecious, with male specimens bearing a single 15–17 cm long, 4–4.5 cm wide, greenish-yellow cone, and female specimens with a single 29–32 cm long, 12–15 cm wide cylindrical-ovoid cone, gray to greenish in color.[3]
