Ficus nota (原產地菲律賓)

Ficus nota is dioecious meaning that plants are either male or female. This one in Sukau is a male tree.
In male figs the gall flowers act as brood chambers for fig wasps and do not produce seeds. Each gall flower contains a single male or female developing fig wasp. Both sexes emerge at the same time and after mating leave the fig via the ostiole.
A female fig wasp carry two things when entering a fig fruit:
1- Eggs
2- Pollen
And this female with achieve one purpose depending on male or female fruit:
1- If it is a male fruit, there will be gall flowers inside ready for the female wasp to lay her eggs in.
2- If it is a female fruit, there will be fruit flower pollinated by female wasp she move around the fruit in search of gall flowers which do not exist.
There are no gall flowers inside the female figs the eggs will never be laid and the female will die inside the female fig. However her legacy will live on in the seeds resulting from the pollination of the female flowers.
