Tree 23-40 m by 40-112 cm; twigs glabrous; stipules glabrous at both surfaces. Leaves glabrous, usually narrowly elliptic, rarely elliptic, 7.5-21 by 3.5-6 cm; acumen 7—10(—15) mm; base acute to sometimes nearly rounded; midrib much prominent on the undersurface; nerves in 11-16 pairs, intra-marginal vein rather inconspicuous, slightly prominent on both under-and uppersurface; reticulation very fine (about half as fine as in M. elegans), slightly prominent on the otherwise very smooth and somewhat glossy uppersurface, inconspicuous to slightly prominent on the rather dull and mostly darker coloured undersurface, rarely more prominent on both surfaces. Petiole rather slender, 12-17 mm. Brachyblast glabrous, often curved at the base, 3-5 cm long; pedicel 2-5 mm; spathaceous bracts glabrous, c. 4.5 cm long. Outer tepals 4, c. 4.5 by 1 cm; inner tepals 8, c. 4-4.5 by 1.5 (the outer ones)-1 (the inner ones) cm. Stamens c. 55, filament c. 1 mm, anthers 8-13 mm, setaceous connective appendage 10-15 mm; gynophore in the observed flowers clearly present. Fruits ellipsoid or ovoid, c. 5-7 by 4-5 cm, pedicel, scars of perianth and stamens, and gynophore all c. 5 mm long or gynophore reduced.
