Shrub up to 3 m. high, the branches sometimes spreading or sarmentose. Young shoots minutely puberulous, bark of older twigs pale fawn, splitting longitudinally. Petioles up to 7 mm. long, the articulation variously situated, from near the lamina to near the stem. Leaf lamina up to 3 (4·5) x 1·4 (2) cm., but usually much smaller, lanceolate, oblong–elliptic or narrowly ovate, the apex acute to obtuse with minute thickened tip, the base cuneate or tapered; both surfaces glabrous; venation inconspicuous above, midrib more prominent below, lateral nerves few, the basal pair often running almost to the leaf apex; margin of leaf narrowly thickened. Leaves often darkening on drying. Acarodomatia absent. Flowers terminal on short lateral branches, solitary or very rarely in 3–flowered cymes, very sweetly scented; pedicels 2–5 mm. long. Calyx tube 2–3 mm. long, glabrous; lobes 7–12, 2·5–5 mm. long, subulate, hispidulous. Corolla white inside, reddish outside; tube 17–32 mm. long; lobes (6) 9–12, (12·5) 15–18 mm. long, oblong, the apex cuspidate, shortly acuminate or trifid. Stamens inserted near the top of corolla tube; filaments short; anthers 2·5–4 mm. long, reaching to within 2–4 mm. of base of corolla lobes. Style either well exserted from tube or c. 5 as long, with bifid stigma of variable form. Fruit usually 2–lobed, 7–12 mm. long when dry, each lobe ellipsoid.
