Note that side veins of the leaf are defined in obvious loops which are distant from the margin of the leaf. This is a useful distinguishing feature from Ficus callosa leaves.
Ficus callosa produces very similar figs.
Ficus magnoliifolia like all Section oreosycea figs is monoecious which means that figs produce both seeds and fig wasps in the same fig.
Note that the figs are attached to the twig by a stipe with the bracts next to the trunk. This is a useful distinguishing feature from Ficus annulata which has similar leaves and figs.
