Fruit on a pedicel 18–25 (34) mm. long; ripe carpels few (c. 5–10), 1–3-seeded, 0.8–1.5 x 0.6–1 cm., ovoid or shortly cylindric, often apiculate, slightly constricted between the seeds when dried, yellow or orange, glabrous or sparsely rusty-pubescent, finely rugose, with stipes 3–8 mm. long.
Petals greenish, not fleshy, subequal or the outer rather longer, 7–13 mm. long, ovate to suborbicular, cucullate, often ± clawed, rugose, glabrous or tomentellous above, tomentellous below.
