Description

It is a cycad with a more or less underground stem, up to 25 cm high and with a diameter of 20-30 cm, often with secondary stems originating from shoots that arise at the base of the main stem.

The leaves, pinnate, erect, 80–120 cm long, are arranged in a crown at the apex of the stem and are supported by a 2 cm long petiole; each leaf is composed of 48-58 pairs of lanceolate leaflets, with a spiny green glaucous margin, inserted on the rachis at an angle of 70-75°.

It is a dioecious species with male specimens that have a single cone, 15–17 cm long and 4–4.5 cm wide, of greenish-yellow color, and female specimens also with a single cylindrical-ovoid cone, erect, long 29–32 cm and 12–15 cm in diameter, gray to greenish in color.[2]
