Inflorescence of single flowers, solitary or clustered in groups of 2, on leafless twigs; peduncles 1–2 by 1–2 mm (in flower), 2–5 by ca. 2 mm (in fruit), sparsely to rather densely covered with appressed white/yellowish ca. 0.1 mm long hairs; pedicels 15–20 by 1–2 mm at the base (in flower), 18–23 by ca. 2 mm (in fruit), sparsely covered with appressed white/yellowish hairs ca. 0.1 mm long or glabrous; 2 lower bracts, deltate, basal to 0.2 mm long, apical 0.3–0.5 mm long, obtuse, mostly persistent, rather densely covered with appressed white/yellowish hairs ca. 0.1 mm long; upper bract mostly attached midway along pedicel, deltate to broadly ovate, 1–2 by ca. 1 mm, obtuse or emarginate, sparsely covered with appressed white/yellowish hairs ca. 0.1 mm long; closed flower buds depressed ovoid, opening in development; flowers green, sometimes tinged with red around margins of petals or creamy yellow in vivo, reddish or dark brown in sicco, sepals and petals glabrous; sepals connate for 0.5–1 mm, broadly ovate, recurved, rarely appressed, 3–4[-5] by 3.5–5 mm, obtuse, soon falling off; outer petals elliptic, 12–22 by 7–12 mm, rounded, inner petals narrowly obovate to narrowly elliptic, 10–24 by 4–7 mm, obtuse; androecium ca. 6 mm diam.; stamens 1.4–1.6 mm long, connective appendage 0.5–0.7 mm wide; gynoecium ca. 1 mm diam.; carpels ca. 25, ca. 2.5 mm long, glabrous. Monocarps 7–17, ellipsoid, slightly asymmetrical, 11–17 by 9–11 mm, green maturing to red, reddish-brown, dark purple or black in vivo, blackish or reddish-brown in sicco, with an excentric apicule; stipes green maturing to red in vivo, 7–14 by 1–1.5(3) mm; fruiting receptacle depressed ovoid, 4–8 mm diam., monocarps, stipes and receptacle glabrous.
