Flower bracts curved, about 0.5-0.7 mm long. Flowers paired but lacking a common peduncle. Tepals pubescent outside, about 12-13 mm long. Hypogynous glands fused to form a +/- 4-lobed, yellow cup surrounding the ovary. Ovary sessile, pubescent. Ovules 2.


Fruits globular or depressed globular, about 5-6 x 5-7 cm. Seed about 4.5 x 5.5 cm. Endocarp + testa no more than about 1-2 mm thick.


First leaves in whorls of 3-5, oblong-obovate, about 15-25 cm long. At the tenth leaf stage: leaf blade linear-obovate, apex acuminate or acute, base cuneate to attenuate, in whorls of 3-4, upper surface glabrous except for a few hairs on the midrib near the base. Seed germination time 10 to 22 days.
