Persea borbonia is a species of the genus Persea within the laurel family(Lauraceae). It occurs only in the southeastern United States . Common English names are: redbay, tisswood, scrubbay, shorebay, swampbay.
The alternate leaves on the branch are divided into a petiole and a leaf blade. The leaves smell aromatic when crushed. The simple leaf blade is lanceolate, measuring 7 to 15 centimeters (3 to 6 in ). The leaf blades vary in color from light to dark green.
The relatively small stone fruit is blue or black when ripe.
Persea borbonia may be slowly becoming extinct due to an invasion of the bark beetle Xyleborus glabratus in the southern United States . This bark beetle was first observed near Savannah, Georgia in 2002 . He transmits a by the fungus Raffaelea lauric cola -induced sickness, the so-called "laurel wilt" ( English laurel wilt ), which is responsible for the death of the trees.
However, some foresters agree that Persea borbonia will not become extinct because it can rejuvenate itself to a certain extent.
Persea borbonia grows along the coasts of the southeastern United States in the lowlands of Texas , Arkansas , Louisiana , Florida , Mississippi , Alabama , Georgia , South Carolina , and eastern North Carolina . Small, isolated populations are found on the coasts of Virginia , near the border of Maryland and Delaware . It also grows in the Bahamas and is cultivated in Hawaii . Usually it grows on the edges of breaks .
The first publication took place in 1753 under the name ( Basionym ) Laurus borbonia by Carl von Linné in Species Plantarum , 1, page 370. The new combination to Persea borbonia (L.) Spreng. was published in 1825 by Kurt Polycarp Joachim Sprengel in Systema Vegetabilium, editio decima sexta , 2, page 268. Other synonyms for Persea borbonia (L.) Spreng. are: Persea littoralis Small , Tamala borbonia (L.) Raf. , Tamala littoralis (Small) Small .
Persea borbonia is used as an ornamental plant for gardens and parks.
Persea borbonia was the subject of research in connection with grafting and hybridization with avocado ( Persea americana ). Potential benefits for disease resistance and tolerance to damp soils and cool temperatures should be identified. Both species rarely form hybrids with one another , if at all . There were two compatible groups of Persea americana and Persea borbonia for grafting, but they did not produce any viable specimens.
