I'm on vacation, so a few of the entries to the end of February will be short. -- Daniel.
Spathodea campanulata is a native of tropical Africa, but has been planted in tropical areas around the world. This has led to a number of common names, with African tulip tree and fountain tree seemingly the most often used in English.
The reason for pantropical spread and planting seems to have been ornamental value. Unfortunately, this species has also been nominated as one of the "world's 100 worst invaders". You can get an idea of its omnipresence in Hawaii (and many other photographs) through the Plants of Hawaii site.
Also, do check out the winged seeds of Spathodea campanulata (or in this page on the Bignoniaceae). Very nifty. Wikipedia alludes to some of the economic (and not so economic) uses of the species.
