Sitting on the banks of the Swan River I photographed some Gum Trees

@MrAboo No. Sweetgums are not related to these gum trees.
These Gum Trees exude a gummy resin when the trunk is damaged, branch falls off etc.

@Gusman is the resin chewable like gum?

@MrAboo Some Gum tree resin is edible. Mostly used for medicinal purposes
