Generative characteristics

The pedunculate, yellow, 30 mm wide flowers have stout, glabrous peduncles. The thin, glabrous sepals are green, but display display yellow colouration towards the apex. The smooth, subglobose, 15-25 mm long, and 14-20 mm wide fruit bears 15-30 ovoid, shiny, pale brown 5 mm long, and 3.5 mm wide seeds.^[2] The flowers are not fragrant.^[3]

Reproduction

Generative reproduction

This species has an outstandingly low number of seeds per fruit.^[2]
