Tree up to 55 m. or more high; bole long, straight, cylindrical; buttresses better developed than in other species, extending up bole for 4–5 m.; bark greyish with pale orange patches, scaling in plates on older trees and leaving shallow depressions behind.. Leaves up to 60 cm. long; leaflets 10–14, opposite or subopposite, oblong-elliptic, up to 18 × 8 cm. (much larger on saplings), apex appearing rounded or retuse, but with a very short abrupt apiculum which is usually twisted and reflexed (sometimes subacute in saplings), base of distal leaflets slightly asymmetric; lateral nerves in 8–12 pairs, venation prominent and reticulate on both surfaces; upper surface dull; lower surface glabrous; petiole scarcely flattened, not winged, glabrous.. Inflorescence up to 25 × 15 cm.. Calyx 0.15–0.2 cm. long, lobed to ± the middle, sparsely puberulous.. Petals 0.6–0.7 cm., glabrous.. Staminal tube 0.4 cm. long, cup-shaped, entire.. Capsule 12–20 × 3–4 cm., cylindric, gradually tapered to the pointed apex; valves similar to those of E. angolense; scars on columella consisting of conspicuous tufts of hairs.. Seeds (including wing) 6–8.5 × 2 cm., attached to the ± central, only slightly zigzag, placental line of each face of the columella by a ± centrally placed hilum.. Fig. 17/1, 2.
