Leaves bright green, subsessile or shortly broadly petiolate (to 1 mm), 20-40 x 12-20 mm, oblong to elliptic-oblong, with margin plane or rarely recurved, paler or glaucous beneath, thinly chartaceous, eventually deciduous at lamina base, apex rounded to retuse, base broadly cuneate; venation: c. 6 pairs main laterals without intermediates, tertiary reticulation obscure; usually only midrib prominent; laminar glands small, dense. Inflorescence (1)3- 5(-8)-flowered, terminal, without accessory flowers; pedicels 3-10 mm long; bracts 1.5-3 mm long, triangular-subulate. Flowers c. 1 5 mm in diam.; buds globose. Sepals 5, 3-5 x 1.5-2.3 m, unequal, tardily deciduous, spathulate to elliptic or ovate, rounded to acute, margin plane, basal veins (1)3, unbranched. Petals 5, coppery yellow, 8-10 x 4-6 mm, c. 2 x sepals, oblong, with apiculus lateral, acute, very short. Stamens c. 60-80, longest 4-6 mm, 0.65-0.75 x petals, deciduous. Ovary 3-merous, c. 3 x 1.5 mm, ellipsoid, suba- cute, placentation incompletely axile; styles 3, 1-1.5 mm long, c. 0.5 x ovary.
