Contents
Taxonomic notes
Synonyms: Tamala borbonia (Linnaeus) Rafinesque.[1]
Varieties: none.[1]
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.[2] Redbay is in the order Ranales (formally called Magnoliids). This order includes magnolias, yellow poplars, pawpaws, anise tree, wild cinnamon, and laurels.[2]
Description
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.[2] P. borbonia is an evergreen, aromatic tree/shrub. Its leaves have an entire margin, an elliptic shape, and glabrous to pubescent underside. They are 5-15 cm long and 2-6 cm wide. The flowers are perfect with axillary cymes on tomentose peduncles that are 2-16 cm long. The drupe is dark blue or black, subglobose, and 7-10 mm in diameter.
Distribution
The native distribution of redbay includes the Coastal Plain from southern Delaware to Florida, west to southeast Texas, with isolated populations in central Texas.[3]
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.[4] Redbay requires partial to fun sun, plenty of water supply, and root oxygen.[2] It does not tolerate long periods of inundation.[5] Soils are mostly Histosols.[6] It grows in loamy sand, sandy loam, and limestone substrate. P. borbonia does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[7]
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.[4]
Phenology
Flowers are perfect and monecious.[2] P. borbonia flowers from April through June and fruits from January through July.[4][8] Cross-pollination is required for viable seeds.[2]
Seed dispersal
Seeds are dispersed by songbirds, white-tailed deer, bobwhite, wild turkeys, and black bears.[6]
Seed bank and germination
Germination is hypogeal.[6] 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 permanently inundated conditions damaging.[2]
Fire ecology
P. borbonia has been described as a late-successional species that does not thrive in areas of disturbance such as fire.[2] 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.[6] However, a study on Long Pine Key in the Everglades found P. borbonia to resprout, flower, and fruit within about one year following a fire in April. The degree and timing of flowering and fruiting did not vary substantially among plots burned one, two, six, and seven years prior.[9]
Pollination
Persea borbonia has been observed at the Archbold Biological Station to host bees from the Apidae family such as Apis mellifera, Bombus impatiens and Epeolus zonatus, plasterer bees from the Colletidae family such as Colletes banksi, C. brimleyi and C. nudus, sweat bees from the Halictidae family such as Augochlora pura, Augochloropsis metallica and Lasioglossum pectoralis, thread-waisted wasps from the Sphecidae family such as Cerceris fumipennis and Tachytes auricomans, and wasps from the Vespidae family such as Mischocyttarus cubensis, Pachodynerus erynnis, Parancistrocerus salcularis rufulus, Polistes metricus and Zethus spinipes.[10]
Herbivory and toxicology
The fruits of P. borbonia are a sizable portion of the bobwhite quail diet during fall and winter months.[6] 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.
Diseases and parasites
P. borbonia is susceptible to laurel wilt disease (LWD) which is a lethal vascular infection in trees of the laurel family cause by the fungus Raffaelea lauricola that is transported by the non-native ambrosia beetle Xyleborus glabratus. Laurel wilt disease is characterized by mortality of redbay stems in the infected sites. Distribution of LWD includes South Carolina, Georgia, Florida and parts of North Carolina.[11] 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. [12]
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.[6]
Conservation, cultivation, and restoration
Cultural use
The wood is often used for cabinetwork and lumber, while the leaves can be used to add spice and flavor to food.[3] Humans use redbay for carpentry trim, flavoring tea and gumbos, and medicinal purposes by Native Americans.[13]
