Flowers 2–5 in a fascicle from defoliate axils, or from old branches, even from the trunk, appearing with the young leaves, up to 10 cm. in diameter; pedicels sparingly glandular, 1.5–2.5 cm. long at anthesis, up to 4 cm. in fruit. Sepals oblong-elliptic, glandular dorsally, subpersistent, 1.2–2 cm. long, 0.7–1.3 cm. broad. Petals ± 10, about twice the size of the sepals, spathulate-oblong, strongly veined towards the base, (1.6–)2.5–4.5 cm. long, (0.6–)1–2.3 cm. broad. Filaments up to 2.5 cm. long; anthers 3–4 mm. long. Ovary tuberculate; style slender, ± 1 cm. long, with 5–6 short stigmatic branches. Capsule elliptic to subglobular, 7–10(–15) cm. long, 4–6(–12) cm. across including the spines (these (1.5–)2–5 cm. long), splitting into 5–6 valves, which recurve when ripe; pericarp ± 5 mm. thick. Seeds numerous, globose, puberulous, 5–7 mm. long, 3–4 mm. broad. Fig. 8/8, 9.
