Flowers sweetly scented, heterostylous, 5-merous, in much-branched often somewhat pyramidal panicles 7–18 cm. long or rarely 3 inflorescences from a node with ± undeveloped leaves resembling bracts; peduncles 4–12 cm. long, glabrous, usually quite noticeably 2-winged and flattened even in life; secondary branches (0.3–)0.6–3.3(–6.5) cm. long; pedicels 2–3.5 mm. long; bracts and bracteoles minute.. Calyx glabrous; tube obconic, 0.8 mm. long; limb cupuliform, 0.3–0.7 mm. long, subtruncate, or lobes very small, rounded, 0.25 mm. long.. Corolla white, cream, pinkish white, greenish yellow, brownish or pale green, glabrous; tube funnel-shaped, 2–3 mm. long; lobes ± ovate, 2–2.5 mm. long, 0.8–1.5 mm. wide..
