Depending on who you ask, there are two laurel oaks in Florida.  Q. laurifolia (swamp laurel oak) and Q. hemisphaerica (Darlington oak, sand laurel oak).  The taxonomists don't agree, and it appears that the two are distinctively different in north Florida but very much alike in southern and south Florida. They are separated here because one is a wetland and floodplain plant, the other grows in dry uplands.  Some authors note that regardless of ID, they get planted without much regard for origin or drainage. Often grown as a specimen tree, fast growing.

It's called "white mangrove" because it exudes extra salt through special glands which makes the leaves appear white. The word "mangrove"  refers to all types of trees that have adapted to living in the sea. Worldwide, there are 23 genera from eight different families that have species that are described as mangroves. Useful in coastal sites both for screening, windbreak, and as a plant useful to coastal stabilization. Plant slightly upslope of red and black mangroves.
