Inflorescence of single, solitary flowers, on leafy twigs; peduncles 1–4 by ca. 1 mm (in flower), 2–5 by 1.5–2 mm (in fruit); pedicels (12–)15–25 by 1 mm at the base (in flower), 14–30 by 1–1.5 mm (in fruit), peduncles and pedicels rather densely covered with more or less erect brown hairs 0.2 mm long; 2 lower bracts, deltate, ca. 1 mm long, soon falling off, rather densely covered with more or less erect brown hairs 0.2 mm long; upper bract attached around midway along the pedicel, ovate or broadly so, 1–3 by ca. 1 mm, obtuse or acute, outer side sparsely to rather densely covered with appressed or erect whitish hairs to 0.2 mm long; closed flower buds depressed ovoid, opening loosely in development; flowers green to greenish-yellow, pale yellow or cream in vivo, dark brown with a lighter brown calyx in sicco, outer sides of sepals and petals sparsely to rather densely covered with erect or appressed whitish hairs to 0.2 mm long, inner sides glabrous to sparsely covered with appressed whitish hairs to 0.2 mm long (or inner petals papillate); sepals free, broadly ovate to deltate, recurved, 3–4 by 2.5–4 mm, obtuse, soon falling off; outer petals (broadly) elliptic to ovate, 9–15 by 7–12 mm, inner petals elliptic, obovate or narrowly so, 8–16 by 4–7 mm; androecium ca. 5 mm diam., stamens 1.2–1.5 mm long, connective appendage 0.7–0.8 mm wide; gynoecium ca. 2 mm diam., carpels ca. 25, ca. 2.2 mm long, sparsely covered with erect golden hairs 0.1 mm long. Monocarps 3–23, ellipsoid, slightly asymmetrical, 10–15 by 7–9 mm, with an excentric apicule, green maturing to pink or yellow through to red, purple and black in vivo, reddish or dark brown in sicco; stipes green maturing to pink or yellow to red in vivo, 7–17 by 1–1.5 mm, increasing to 3 mm diam. when mature; fruiting receptacle 3–8 mm diam.; monocarps, stipes and receptacle sparsely to rather densely covered with erect whitish hairs 0.1 mm long. Seeds ellipsoid, orange-brown, shallowly pitted, 5–8 by 3.5–6 mm, raphe sunken, regular.
