Leaves ovate to broadly ovate, 5-14 by 3-10 cm, rounded at the base, gradually attenuate or shortly acuminate towards the obtuse mucronulate apex, glabrous; midrib and 5-6 curved lateral nerves on either side impressed above, prominent beneath; secondary nerves nearly parallel, prominulous on both sides or indistinct above; tertiary nerves reticulate, prominulous above, flat beneath; petiole 1-3 cm, narrowly sulcate above, glabrous. Inflorescences axillary, more or less secund, to 12 cm long, corymbosely branched at the apex, many-flowered; peduncles to 8 cm, terete, glabrous or pubescent towards the apex; branches of the inflorescences short, pubescent. Pedicels 12-16 mm long (in fruit 25-35 mm), glabrous or pubescent at the base, slightly thickened and subangular at the apex. Lower bracts foliaceous, to 3-5 cm long, upper ones subulate, ca 1½ mm long. Flower-buds ovoid, acute to obtusish. Sepals glabrous, two outer ones subcoriaceous, broadly oblong, rounded at the apex, ca 7 mm long, three inner ones broadly elliptic to orbicular, retuse at the apex, 8-9 mm long, subcoriaceous in the middle portion, and with membranaceous margins. Corolla campanulate to broadly funnel-shaped, ca 1½ cm long, yellow (or sometimes white?), glabrous, limb hardly lobed, crenulate(?). Dilated base of the filaments curved, and papillose at the margins; anthers straight. Ovary glabrous.
