Red mangrove trees are most often found closest to the water’s edge, with black mangroves and white mangroves following suit inland in that order. The pencil-shaped pneumatophores originate from underground horizontal roots projecting from the soil around the tree’s trunk, providing oxygen to the underground and underwater root systems. Seeds sprout into 1 inch (2-3 cm), lima bean-shaped propagules. tide zone, Propagation: Rhizomes, No part of this online publication may be If the propagule strands in a “favorable” area, there is an obligate stranding period before the primary roots and cotyledons (primary leaves) emerge. Tangles of prop roots along the coast trap sediment that moves with the tide, which gradually builds up soil around the plants. It grows at elevations slightly higher than the red mangrove where tidal change exposes the roots to air. Trunks and limbs are covered with gray bark, over a dark red wood from which the common name originates. The black mangrove reaches heights of over 65 feet (20 m) in some locations, however in Florida they are smaller with heights to 50 feet (15 m).

The leaves are semi succulent, green and have two red notches located at the base. However, when it is found in oxygen-depleted sediments or flooded for extended periods of time, it often develops peg roots. for biotopes that allow for the root system to be partially above Reproductive adaptations enable seedlings to germinate while still attached to the parent tree. The smooth-edged, elliptical leaves have shiny, dark green uppersides and pale green undersides and occur opposite from each other along the branches. This small tree or shrub grows rapidly in rich soils to heights of 50 feet (15 m). is difficult to grow in the marine aquarium. There are two salt-excreting glands located at the base of each leaf.

Botanists believe that mangroves originated in Southeast Asia, but ocean currents have since dispersed them to India, Africa, Australia, and the Americas. Growing along the edge of the shoreline where conditions are harshest, the red mangrove (Rhizophora mangle) is easily distinguished from other species by tangled, reddish prop roots. One of the The white mangrove features a pair of nodular, salt-excreting Laguncularia is most commonly found further inland and unlike the other mangrove species found in Florida and the Caribbean the white mangrove does not have a system of specialized roots, such as prop roots or pneumatophores. They grow in dense patches along the high tide mark of estuaries and brackish swamps and mud flats. Habitat range in Florida is limited by temperature; however, the decreasing frequency, intensity, and duration of winter freeze events in North Florida has likely played a role in expanding the range of both red and black mangroves along the Panhandle coastline.

The white mangrove (Laguncularia racemosa) can occur almost anywhere in a wetland, but is mostly found in higher elevations, such as the inland edges. Two glands at the base of each leaf act as perspiration glands removing excess salt and sugar to attract helpful insects.
