    Leaves sometimes immature at flowering; mature blade elliptic(-lanceolate) or ± obovate, 4–14 × 1–6 cm, base cuneate or attenuate, apex acute or attenuate, apiculate, leaf buds densely pale-strigose but soon glabrescent except along margin and midrib beneath; petiole 0–10 mm.
    Inflorescences
    Inflorescence a congested head or spike 1.5–8 cm long terminating main and short lateral branches, sometimes with additional flowers in upper leaf axils, each cymule 1(3)-flowered; bracts usually white in proximal half, green above and along main veins, rarely green throughout, obovate to broadly spathulate, 7.5–16 × 3.5–12.5 mm, apex rounded, truncate or emarginate then shortly attenuate into a mucro, main veins and margin of distal half strigose, margin of proximal half usually with spreading, bulbous-based hairs, surface with short (rarely subsessile) glandular hairs in distal half, sometimes with interspersed finer short eglandular hairs, few broad sessile glands usually present towards base; bracteoles white with green midrib, rarely green with pale margin, linear-lanceolate or lanceolate, (5.5)7.5–14 × 1–2 mm, mucronate.
