Characteristics

Mature leaves opposite; petiole not markedly thickened, at most c. 1 mm long; lamina 3.5–7 × 0.8–2.4 cm, ovate to lanceolate, base narrowly and long cuneate, apex long acuminate, shiny or dull above, dull beneath, midvein prominent on both sides, but especially beneath, with 30–40 fine, sometimes rather irregularly sinuous lateral veins; tertiary veins form a scalariform or irregular reticulation between the lateral veins; a thin, but usually clearly visible submarginal vein present along the entire lamina.
More
Female inflorescences consist of a 3–5 mm long axis with 4–6 pairs of decussate scale-like bracts with prominent midvein, c. 3 × 2 mm, and one terminal female flower, at anthesis with perianth and ovary almost completely enclosed by upper bracts; protruding stigmas c. 3 mm long.
Shrub or small tree, up to at least 8 m high; twigs with yellow-green fissured bark and alternate lines running down from each petiole, internodes 3–5 cm long, some scale-like bracts often present above the leaves on the younger stems, perhaps from rudimentary inflorescences.
Male inflorescences with shorter axis than female, with 2–3 pairs of decussate scale-like bracts; male flowers apparently all terminal; perianth 4-merous; stamens 4, with sessile or subsessile anthers, 2–3 mm long; no pistillode present.
Mature fruits brown,7–10 × 6–8 mm, turbinate, excluding the three c. 8 mm long persisting style bases, with faintly verrucose exocarp and detaching endocarp.
Inflorescences (only very few seen) unisexual, axillary or slightly above leaf-insertion.
Juvenile individuals with very closely set linear leaves, c. 2.5 × 0.2 cm.
Seeds dark brown, slightly curved, c. 5 × 2 × 2 mm.
