Short shoots opposite and decussate, each bearing 2-4 leaves and/or 1-5 capitula; older short shoots rough with closely packed leaf bases. Leaves opposite or in opposite fascicles, elliptic to suborbicular or broadly obovate to broadly spathulate; lamina c. 4 - 8(-10) × 3-6(-7) mm, upper surface bright glossy green when fresh, ± glabrous, smooth and flat, midrib above pale and not raised; main veins obscure; margins red or red-brown; lower surface silvery white with dense appressed tomentum, midrib beneath brownish and raised in proximal half, becoming obscure distally; apex obtuse, with a minute, brownish apiculus; base of lamina tapering abruptly to petiole. Petiole reddish, narrow-cuneately winged, c. (0.5—)1.5—3(—4) mm long with appressed tomentum beneath, glabrous or with sparse subappressed hairs above. Juvenile leaves similar but with a few darkened denticles on margins as well as at apex. Capitula in clusters of (1-)2-4(-5) on leafless or leafy short shoots, 6-7 mm long, scented. Peduncle 1-2 mm long, soft and flexible; bracts opposite, ovate, hairy, 1-1.5 mm long.
