Inflorescences (1–)2–6(–10)-flowered, mostly exceeding whorls when mature; peduncles (2–)3–12(–20) mm long; pedicels (1.5–)3–10 mm long. Corolla 1.5–2.5 mm diam., cream or greenish-cream, sometimes tinged purple-red abaxially. Fruit depressed-globose, c. 1–1.2 mm long; mericarps ellipsoid to sub-globose or reniform, touching one another, rugose, dark reddish-brown or dark brown, covered with short pustules that usually mature into rounded or triangular protuberances.
