Black Mangrove (Avicennia germinans)

So called for their dark-coloured bark, the leaves on this species are dull and dark green on the top and whitish green or gray below. They are also more elongated and pointy than the other species. Oftentimes there is a salty crust on the underside, since the leaves aid in salt exchange. Black mangrove is most notable for its snorkel like roots, called pneumatophores. These may be found sticking out of the sediment several meters from the base of the tree. They aid in air, nutrient and salt exchange, so they are in many ways functionally similar to the red mangrove's prop roots.

Black propagules are smaller than the red's, and are gray in colour. The seeds flow with the tide until the fruit wall falls, allowing the seedling to send roots into the substrate.

Blacks can develop a very stately and tall main trunk. Therefore, these mangroves are excellent windbreaks along the shoreline. Black mangrove is also more tolerant of salt, and basin environments than the other species.
