Encephalartos paucidentatus is a species of cycad.

It is endemic to the mountains near Barberton in Mpumalanga Province, and near Piggs Peak in the northwestern part of Eswatini, in South Africa .

It grows at elevations of 1,000 to 1,500 meters.[3]

Description

It is a cycad with an erect stem, up to 6 m tall and with a diameter of 40–70 cm, rarely with secondary stems originating from shoots that arise at the base of the main stem.

The leaves, pinnate, 1.5–2.5 m long, are arranged in a crown at the apex of the stem and are supported by a 20–30 cm long petiole, without thorns; each leaf is composed of numerous pairs of lanceolate leaflets, with a toothed margin, on average 15–25 cm long, bright green to yellowish-green, inserted on the yellowish rachis.

It is a dioecious species with male specimens showing 1–5 cones, spindle-shaped, 40–60 cm long and 12–15 cm broad, of golden-brown color, and female specimens with 1–3 ovoid cones, 30–50 cm long and with a diameter of 20–25 cm, yellowish in color.

The seeds are roughly ovoid, 35–40 mm long, covered with a bronze-colored sarcotesta.[4]
