This cycad grows to 6 metres tall with a trunk diameter of 50 cm. It has glossy dark green leaves. The leaflets are curved and tapering, with a spine at the top and several teeth along the margin.[2]
Like other cycads, E. ituriensis is dioecious, with both male and female trees. Male trees have 1–4 pollen cones, narrowly ovoid. Female trees have 1 or 2 seed cones, which are ovoid and 18–20 cm long. The seeds have a red sarcotesta.[2]
