Terrestrial shrub, 3-5 m, or small tree, with straight, erect branches. Branchlets glabrous, terete; internodes 2-8 cm. Leaves in ± terminal, 2-4-merous pseudowhorls, elliptic or mostly elliptic-lanceolate, rarely obovate-elliptic or oblong-oblanceolate, apex acute, base narrowed, ± coriaceous, glabrous, 6-12(-15) by (2.5-)3-5(-6) cm, midrib impressed above, much raised beneath, nerves 9-12 pairs, straight, spreading and ± parallel, initially slightly prominent or somewhat impressed, more conspicuously inarched in mature leaves above, prominent beneath, veins slightly or not visible; petiole often red in fresh specimens, somewhat winged, (6-)8—12(-15) mm. Inflorescences 2-4, each in the axil of one of the upper leaves; inflorescences 2-4-flowered. Floral buds ovoid-oblong, subacute, c. 2.5 by 0.8 cm. Outer perulae small and ovate, obtuse, inner ones gradually larger and ovate to ovate-oblong or obovate-oblong, all glabrous or rather faintly sericeous outside especially towards the tip, densely white-ciliate. Bracteoles linear, glabrous, up to 2.5 by 0.1 cm. Pedicels rather slender, glabrous, (1-)1.5-2.5 cm. Calyx very small, margin undulately lobed, glabrous. Corolla funnel-shaped, deeply 5-lobed, 3.5-4 cm long in all, tube 1-1.5 cm, base 5-saccate, 3-4 mm ø, lobes oblong, subacute, ± spreading, 2-2.5 by 0.5-0.9 cm, glabrous, mostly white with a yellow spot inside on the upper lobe, also rose or of a clear orchid-purple with a ± orange spot, rarely reddish, fragrant. Stamens normally 10 (sometimes a few more), ± as long as the corolla; filaments linear, hairy except the very base and upper half, occasionally entirely glabrous; anthers short-oblong, 2.5 by 1 mm. Disk glabrous. Ovary glabrous, cylindric, slightly 5-ribbed, mostly continuous (rarely abrupt) with the glabrous style, c. 3 cm long; stigma capitate. Capsule ovoid-fusiform, rather deeply 5 grooved, 2-2.5 by c. 0.6 cm, beaked by the persistent rest of the style even after the capsule is split into 5 rather thin, not twisted valves. Seeds flat, broad-oblong, very shortly and irregularly winged (not tailed) on both ends, c. 2 mm.
