This is a diagram depicting the Marronian reproductive process. More info on marronians can be seen here https://www.furaffinity.net/view/53947718/

A marronian, male, female, or other, any Marronian gives off spores passively, which is caught by these trees, this fleshy tree creates a child in this sort of symbiosis, due to this passive reproduction and the direct parents often being ambiguous, the town generally works together on raising a child.

These spores can actually have an effect on unborn humans, this often ends up with the human being born with longer canine teeth, slightly pointed ears, sometimes horns, though this is very uncommon.
