This species is often found growing in clusters and the stem is usually subterranean. If a stem develops above ground, it may grow to a height of up to 0.4 m and a diameter of 250 mm, with the occasional sucker. The young leaves are densely covered with white hairs. The mature leaves are dark green, glossy and lighter green on the underside of the leaves. The leaves are 1.5 to 3 m long, with the median leaflets ranging from 150 to 250 mm in length. The width of the leaflets are 15 to 20 mm. This species produces 1 to 4 cones on the female plants. The male cones are lemon-yellow, 600-700 x 120-150 mm, and can bear up to 5 cones.
