Description
editIt's a tree-like cycad, growing up to 2 m tall and 40 cm wide at its base, often with additional shoots sprouting from the bottom. Its bluish leaves form a crown at the top, reaching 60–80 cm in length, sometimes twisted. The lance-shaped leaflets, 12–17 cm long, angle oppositely along the rachis at 45°, with smooth margins and occasional small teeth on the lower side. The straight petiole has small spines. It's a dioecious species, with green ovoid male cones, 35–50 cm long and 10 cm wide. Female cones, 30–45 cm long and 18–25 cm wide, are of similar shape, with up to three growing on each plant. The macrosporophylls have a warty surface. Seeds are oblong, 30–35 mm long, covered by a yellow sarcotesta.[4]
