Each bract is a cup shaped structure with crescent shaped glands and contains one female flower and several male flowers, the male flower has one stamen and the female flower a single 3 lobed ovary with 3 styles which are forked. The fruit is a small capsule, up to 5mm across, which splits to release 3 smooth seeds.
