Leaves opposite, ovate-elliptic or oblong-elliptic, acute-acuminate, pubescent beneath, often rather brittle, prominently nerved, lateral nerves 10-20 pairs; blades mostly 7-15 cm long and 3-5 cm wide, rounded at base, dull green, downy on the underside, aromatic when crushed. Flowers hermaphroditic, solitary or 2-4 together in leaf axils, rather large (2.5 cm wide); peduncle about 1-2 cm long, pubescent; calyx 4-5-lobed (anthesis, not before) about 6-8 mm long, petals white, 10-15 mm long, fugacious, usually 4 or 5, obovate, slightly concave, stamens numerous (c. 200-250), white, about as long as petals; style 10-12 mm long, stigma peltate.
