Ceiba pentandra

A giant in the rainforests, the kapok tree can reach up to 200 feet in height, sometimes growing as much as 13 feet per year. Due to its extreme height, the kapok, or ceiba tree, towers over the other rainforest vegetation. The trunk can expand to nine or 10 feet in diameter. In the nooks and grooves of this huge plant live a diverse number of species including frogs, birds and bromeliads. The kapok tree is deciduous, shedding all of its leaves during the dry season. As its seeds are easily blown into open areas, kapok trees are some of the first to colonize open areas in the forest. The white and pink flowers of the kapok tree emit a foul odor that attracts bats. As the flying mammals move from flower to flower feasting on the nectar, they transfer pollen on their fur, thus facilitating pollination. The kapok tree does a great job at spreading its seeds, producing anywhere between 500 and 4,000 fruits at one time, with each fruit containing 200 seeds. When these fruit burst open, silky fibers spread the many seeds all over the forest.

This prehistoric tree when immature has spikes on its trunk and branches and  looks like something out of Jurassic Park. This is one of my favorite native trees.
