    Leaves
    Leaf blades (3)5–11.5 × (1.5)2.5–6.4 cm, elliptic or obovate, obtuse, acute, subacuminate or less often acuminate at the apex, cuneate or sometimes somewhat rounded at the base, stiffly chartaceous, slightly glossy and glabrous or with scattered hairs on upper surface, with scattered hairs or softly pubescent beneath; midrib hairy on both sides, usually drying creamy in colour, prominent beneath; lateral nerves in 4–6(8) main pairs, pubescent beneath; tertiary nerves discolorous but not raised; domatia inconspicuous or occasionally as conspicuous hairy tufts; bacterial nodules mostly 2 or sometimes more, linear, up to 3(6) cm long, situated along the basal half of the midrib but sometimes reaching almost the tip of the leaf; petiole (2)3–8(10) mm long, pubescent; stipules puberulous or pubescent or glabrous, the lobes sheathing at least at base, truncate to triangular, 1.5–3 mm long, each bearing an awn, 1–2(3) mm long.
    Flowers
    Flowers sweet- scented, 8(9)-merous, 1–2, usually borne at nodes from which the leaves have fallen, but occasionally in leaf axils; subsessile; bract and bracteoles 3, cupular, 1–3 mm high, each with 2 unequal pairs of awns, pubescent outside.
    Calyx
    Calyx tube glabrous or pubescent; limb 6–10 mm long, ellipsoid and closed in bud, with an apiculum 1–2 mm long, splitting into 2–3 lobes when the corolla opens, thin in texture and often translucent, silky pubescent outside.
