Description
editThis cycad is tree-like, growing up to 3.5 meters tall with a stem diameter of 25-35 cm. It sometimes develops additional stems from suckers at its base. Its pinnate leaves can reach 1 meter in length, supported by a 22-25 cm long petiole. Each leaf is made up of many pairs of lanceolate, leathery leaflets that are 12-15 cm long, with smooth edges and a sharp tip. This species is dioecious, with male plants bearing 1 to 5 cylindrical-fusiform cones, 30-40 cm long and 9-10 cm wide, in yellow to brown hues. Female plants produce 1-5 cylindrical cones, 20-30 cm long and 10-15 cm wide, in a light yellow color. The seeds are roughly oval-shaped, 2.5-3.5 cm long, and covered with a yellow-orange sarcotesta.[4]
