Does there exist a tree that only has flowers and no leaves?

Down in Puerto Rico (tropical) Ive seen a tree in a few ocasions that never has leaves. It only has this big yellow flowers (like big roses, but it has a hibiscus look too) at the end of its branches. I wonder does it ever have leaves.

Some plants don't have leaves, but instead have photosynthetic stems. The cactus is an example of this kindof a plant. It also uses the succulent stem to store water. Parasitic plants also often do not have leaves or the the leaves are rudimentary and not used for photosynthesis. They extract food from other plants and do not need to make their own food.
