The plants are dioecious, with separate male and female trees.

A group of six female trees with one male for pollination could yield several thousand seeds per year.

The genus is dioecious, having separate male and female trees.

The male sends the pollen out in the breeze, not knowing where there might be a female tree.

Most urban park departments are well aware of the female tree's negative quality and exclude it.

The plants are dioecious, have male and female trees independently.

Male and female copal trees have different characteristics, which influence what is made.
