Taxonomic notes
This species has had many scientific names since its discovery. The genus name Persea is derived from a Greek term for a Persian tree with fruits growing from the stem[1].
Redbay is in the order Ranales (formally called Magnoliids). This order includes magnolias, yellow poplars, pawpaws, anise tree, wild cinnamon, and laurels[1].
Description
A description of Persea borbonia is provided in The Flora of North America.
There are five different varieties of redbay in the southeastern U.S., they can be easily differentiated by the flower/fruit stem lengths, and trichomes on the abaxial leaf side[1].
Distribution
The native distribution of redbay includes the Coastal Plain from south Delaware to Florida, west to southeast Texas, with isolated populations in central Texas[2].
Ecology
Habitat
In the Coastal Plain in Florida, P. borbonia has been observed in cabbage palm-live oak hammocks, pine/scrub oak communities, mixed hardwood forests, vegetated shell mounds, tropical evergreen hardwood forests, dune thickets, oak-hickory-magnolia coastal hammocks, and wet pine flatwoods. It has been found in disturbed areas such as bulldozed turkey oak/longleaf pine communities and roadsides (FSU Herbarium). Redbay requires partial to fun sun, plenty of water supply, and root oxygen[1]. It does not tolerate long periods of inundation(Conner and George 1993). Soils are mostly Histosols [3]. It grows in loamy sand, sandy loam, and limestone substrate. Associated species include Gordonia lasianthus, Quercus geminata, Celtis, Exothea paniculata, Xanthoxylum, Fagara, Persea littoralis, Rapanea guianensis, Parthenocissus quinquefolia, Plumbago scandens, Bumelia, Forestiera, Rhizophora, Baccharis halimifolia, black cherry and hackberry (FSU Herbarium).
Phenology
P. borbonia has been observed flowering April through May and fruiting January through July (FSU Herbarium).
Flowers are perfect and monecious[1]. They flower April through May and fruit January through July (FSU Herbarium). Cross-pollination is required for viable seeds [1].
