    Shrubby herb or soft-wooded shrub to 5 m tall; young stems quadrangular and longitudinally furrowed but not winged, glabrous or with a few hairs at nodes
    Leaves
    Leaves with petiole 1–3 cm long on larger leaves without or with a few long spreading hairs on edges; lamina ovate to elliptic, largest 11–24 × 4–8.5 cm, apex acuminate to cuspidate, base attenuate, glabrous or with a few hairs along midrib and veins beneath, without (rarely a few) hairs on edges
    Inflorescences
    Inflorescences at first capitate but soon elongating into racemes to 5(–15 in fruit) cm long; peduncle up to 2.5 cm long, winged, glabrous; internodes to 2 cm long in elongated racemes, winged; pedicels to 1 mm long; bracteoles lanceolate to oblanceolate, 10–15 mm long, never with apical part recurved, glabrous
    Calyx
    Calyx 10–14 mm long, glabrous, lobes linear-lanceolate, subacute, apical part often recurved
    Corolla
    Corolla white, hairy on lobes and in a thin dorsal band; tube below attachment of stamens 3–5 mm long, throat 20–25 mm long and 15–20 mm in diameter apically, lobes 4–7 mm long, acute or bifid at apex
    Filaments
    Free part of filaments 8–15 and 10–17 mm long, densely hairy along their whole length; anthers 3–4 mm long; ventral stigma lobe ± 2 mm long
