Taxonomic notes
Synonyms: Tamala borbonia (Linnaeus) Rafinesque; Persea borbonia var. borbonia
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. [3] Redbay requires partial to fun sun, plenty of water supply, and root oxygen.[1] It does not tolerate long periods of inundation.[4] Soils are mostly Histosols.[5] 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. [3]
Phenology
Flowers are perfect and monecious.[1] P. borbonia has been observed flowering April through June and fruiting January through July.[3][6] Cross-pollination is required for viable seeds.[1]
Seed dispersal
Seeds are dispersed by songbirds, white tailed deer, bobwhite, wild turkeys, and black bears.[5]
Seed bank and germination
Germination is hypogeal.[5] Seeds germinate well in mucky, swampy, and poorly drained areas; however, these conditions may be stressful to an adult tree. Adults require water and plenty of root oxygen which makes perminant inundated conditions damaging.[1]
Fire ecology
P. borbonia is a late successional species that does not thrive in areas of disturbance such as fire.[1] Menges et al. (1993) found that P. borbonia densities and basal areas had increased in flatwoods and bayhead communitites that were fire suppressed for over 20 years. Fire may cause substantial damage to redbay; fire scarring and deterioration of the lower trunk portion of the tree is common.[5]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Persea borbonia at Archbold Biological Station: [7]
Apidae: Apis mellifera, Bombus impatiens, Epeolus zonatus
Colletidae: Colletes banksi, C. brimleyi, C. nudus
Halictidae: Augochlora pura, Augochloropsis metallica, Lasioglossum pectoralis
Sphecidae: Cerceris fumipennis, Tachytes auricomans
Vespidae: Mischocyttarus cubensis, Pachodynerus erynnis, Parancistrocerus salcularis rufulus, Polistes metricus, Zethus spinipes
Use by animals
Fruits are a sizable portion of the bobwhite quail diet during fall and winter months.[5]Redbay rupes are eaten by songbirds, wild turkeys, quail, rodents, deer, and black bear. The leaves are also the primary larval food source for the Palamedes swallowtail butterfly.Cite error: Closing </ref> missing for <ref> tag The greatest decline in redbay populations is in Georgia (Fraedrich et al. 2008).
P. borbonia is also the primary host of a psyllid leaf-galler Trioza magnoliae, which produce galls on leaves. Galls use up resources that would otherwise be used for plant growth, therefore directly affecting plant fitness. [8]
It is resistant to the fungus Phytophthora cinnamomi which affects the roots of many other laurel species. This resistance is due to borbonol found in the roots and stems that is an antifungal substance.[5]
Conservation and management
Cultivation and restoration
The wood is often used for cabinetwork and lumber, while the leaves can be used to add spice and flavor to food.[2]
