unisexual

In unisexual flowers it is not uncommon to find vestiges of the undeveloped stamens in the form of filiform bodies or scales.

Flowers small, unisexual, dicious (male and female flowers on separate plants), sometimes enclosed in calyx-like bracts.

The florets are unisexual, the “ray” florets being female, the “disk” florets male.

The flowers, which are often unisexual, are wind-pollinated.
