Discussion

In the flora area, Lumnitzera racemosa is known from a single naturalized population in Miami-Dade County.

The open, white flowers of Lumnitzera racemosa are self-compatible and pollinated by bees, butterflies, moths, and wasps. The trees show high fruit set and the fruits, which have a corky outer layer, are water dispersed. The species shows invasive potential; eradication procedures have been attempted, and the cultivated specimens at Fairchild Tropical Botanic Garden have been removed (J. W. Fourqurean et al. 2010).
