Erect shrub or small tree 2–20 m tall, glabrous to tomentose, overall indumentum without glands, bark grey to whitish, rarely dark brown, smooth and flaking in plaques; young branches smooth or striate, frequently lenticellate, glabrous to tomentellous. Leaves (7–)9–43 cm long including petiole (0.7–)1.5–9(–10) cm, rachis slightly striate or grooved, frequently lenticellate, hairs not glandular; leaflets rotund to elliptic or narrowly elliptic, occasionally obovate, (2.5–)3–17.5≈(1.2–)2–5.7(–10.5) cm; terminal leaflet usually larger, apex retuse to cuspidate, sometimes unequal, base rounded to cuneate, frequently unequal, margins entire or crenulate-sinuate, occasionally crenate or serrate, hairs occasionally confined to veins and midrib, secondary venation reticulate, lower surface usually with fine gland dots throughout and large scattered glands either side of the midrib towards the base. Inflorescence up to 48 cm long including peduncle, most parts including calyx frequently with long white hairs when young, glabrous or pubescent to tomentose, sometimes lenticellate, pedicels frequently with small glands just below the calyx. Flowers fragrant, often precocious, bracts 3–4≈0.5–0.7 mm, corolla falling off soon. Calyx (4–)5–10(–12) mm long, campanulate, truncate with sinuate margins, or lobes broadly triangular to obtuse, up to 3 mm long, frequently with small mealy glands, usually with larger scattered peltate glands towards the apex, occasionally viscid. Corolla pinkish-white, reddish-pink, pale lilac to purple, usually with darker lines into throat, (2.3–)3–6(–6.5) cm long, lobes ± 1/3 the length of the tube, broadly ovate, margins undulate, densely pubescent outside and on the palate, with glandular hairs in the lower part of the tube inside. Stamens: filaments of anticous stamens 1–1.5 cm long and of posticous 0.7–1.2 cm long, glabrous, glandular-pubescent at base; thecae ± 2 mm long. Pistil with cupular disk at base, slightly lobed. Fruit 15–60 cm long, glabrous or puberulous, finely lenticellate, often with scattered peltate glands. Seeds 5≈3≈3 mm, wings 6–7≈2–3 mm. Fig. 9, p. 39.
