Kou (Cordia subcordata) is an indigenous tree that was also brought over by Polynesian settlers. It was highly prized for its wood, which was used to make bowls and other containers.
The flowers are beautiful, too. Less than two inches across, they grow in clumps, which are sometimes hidden by the shiny green leaves. The flowers are followed by small, round green fruits (seen in the photos to the left and below) which harden to a dark brown and contain white seeds.
The flowers on this tree were popular with a variety of insects including a honey bee, above, and a paper wasp (Polistes exclamans), below.






Royal poinciana (Delonix regia) is also known as the flame tree. As well as producing a stunning array of crimson flowers, it has lacy-looking leaves and produces long, distinctive seed pods.



I’ve posted a photo of a cannonball tree (Couroupita guianensis) before, 
The main attraction of Wailuku River State Park, in Hilo, is Rainbow Falls. But at the top of the hill are these huge banyan trees.
