Cymes terminal and lateral, 15–50+-flowered, densely congested, ± spheroid clusters 3–5 mm wide. Flowers 5-merous, cylindric, with enlarged hypanthium and calyx constricted then widening distally, 1.2–2.2 mm, pubescent, sometimes only slightly so, mostly proximally with straight or usually hooked hairs; sepals redbrown, white distally, midrib and lateral pair of veins becoming prominent, linear to oblong, 0.6–1.2 mm, papery, margins white, 0.03–0.1 mm wide, papery, apex terminated by mucro, hood obscure, narrowly rounded, mucro short-conic, 0.05–0.1 mm, glabrous; staminodes triangular, 0.2–0.4 mm; style 1, cleft (2-lobed or 3-lobed) in distal 1/5, 0.5–1.3 mm.
