Discussion

Laguncularia racemosa is an important component of mangrove swamps in central and southern Florida (extending northward to Levy County on the Gulf Coast and to Volusia County on the Atlantic Coast); it also recently has been reported from Willacy County, Texas. The species is occasionally cultivated as an ornamental tree or shrub in coastal situations. The flowers are quite fragrant and are pollinated by bees. The fruits are semiviviparous, the green embryo piercing the seed coat while the fruit is still on the tree. Some populations have some plants with bisexual flowers and others with staminate flowers, while in others all flowers are bisexual. The frequency of staminate plants in Florida is variable (0–68%).
