Description

It is a cycad with a trunk at least partly underground, up to 1.5 m high and with a diameter of 25-30 cm, often with secondary stems originating from shoots that arise at the base of the main stem.

The leaves, pinnate, 60–90 cm long, are arranged in a crown at the apex of the stem and are supported by a 10-20 cm long petiole, without thorns; each leaf is composed of numerous pairs of lanceolate leaflets, with an entire margin, of an average length of 9-12 cm, of olive-green color, inserted on the yellowish rachis.

It is a dioecious species with male specimens that have 1 or 2 cones, cylindrical-conical, 13–22 cm long and 5–7 cm broad, sessile, covered with a greyish tomentum, and female specimens with 1 or 2 cylindrical-ovoid cones, pedunculate, 20–30 cm long and 16–18 cm in diameter, greenish-yellow in color, also thickly tomentose, gray to brown in color.

The seeds are coarsely ovoid, 20–30 mm long, covered by a yellow-orange to amber color sarcotesta.[2]
