Cymes terminal, 15–200+-flowered, branched, densely to loosely grouped to form subcorymbose clusters 5–50 mm wide. Flowers 5-merous, narrowly ellipsoid, with slightly enlarged hypanthium and calyx tapering distally, 2.3–3.5 mm, glabrous to slightly puberulent proximally with straight to hooked hairs; sepals redbrown, white or whitish distally, veins absent, narrowly oblong to lanceolate-oblong, 1.4–2 mm, papery, margins white, ca. 0.1 mm wide, papery, apex rounded, hood formed from slight incurving, awn or mucro absent; staminodes narrowly oblong, 0.4 mm; style 1, cleft in distal 1/10, 1.3–1.7 mm. Utricles ovoid to ellipsoid, 1–1.2 mm, rugulose, glabrous.
