This is a red mangrove, Rhizophora mangle , on a protected Atlantic coast of Florida, near Fort Pierce.
Mangroves are well adapted to the anoxic sediments into which the roots extend.

The mangrove trees have unique biological adaptations to survive this marine environment, including reproductive biology, salt tolerance, and growth form. Here the reproductive structures of the genus Rhizophora , is shown including flowers, fruits, and the distinctive propagule. The mangroves are unique in that the seed germinates while still attached to the tree. A cigar-shaped seedling may drop to the water to float away, or it may drop and stick directly in the mud and grow.
