Leaves sessile or very shortly petiolate, thinly coriaceous, not glaucous, 3–12 × 2.5–6 mm, elliptic or oblanceolate to subcircular, apex rounded, margin markedly undulate-crenulate, base broadly cuneate, with 2–3 pairs of ascending lateral veins; laminar glands pale, punctiform, distal, small; intramarginal glands pale, small, dense to spaced. Inflorescence 1–5(– 25)-flowered, corymbiform, 10–20 mm long, with lateral branches straight, broadly ascending, ‘cymules’ 1-flowered, without flowering branches below; bracts and bracteoles ovate-lanceolate, minutely black-glandular-ciliate.
