Quercus sinuata var. sinuata, commonly called Durand oak, is a variety of Quercus sinuata , a species of oak tree [1] that grows in parts of the southern United States and northeastern Mexico. [2]
The common name Durand white oak most often refers to this taxon. [3] The less specific common name bastard oak may refer to either of the two varieties of Quercus sinuata, var. sinuata and var. breviloba. Other common names include bastard white oak and bluff oak, but these names more often refer to Quercus austrina . [4] For clear differentiation in common reference, American Forests uses bluff oak to mean Quercus Austrina, [5] Durand oak [6] to mean Quercus sinuata var. sinuata and Bigelow oak [7] to mean Quercus sinuata var. breviloba, a shrubby variety of Quercus sinuata distinguished in part from var. sinuata by its habit of forming clonal colonies in parts of its range. [8] [9]
Quercus sinuata 12. foliis sinuatis laevibus obtusis supra pallidis, subtus subglaucis, glandibus mediocribus globosis calyce subplano. [10]
Quercus sinuata 12. Smooth, sinuate leaves, broadly rounded or blunt at the tip, pale above and almost blue-green with a whitish bloom on the underside, acorns moderately spherical with almost flat cupules.
Synonymous names for this taxon include Quercus durandii Buckley (1861) and Quercus undulata Engelm. (1878). Because it was given by Samuel Botsford Buckley to name some taxons he believed to be varieties but are now understood to be separate species, the term "durandii" is currently regarded as "nomen confusum." [11] The honorary association with Elias Magloire Durand is preserved in the most widely accepted common name for this taxon, "Durand oak."
Quercus sinuata, first described by Thomas Walter in Flora Caroliniana in 1788, claims no subspecies and only two varieties, var. sinuata and var. breviloba.
Quercus sinuata var. sinuata (Latin quercus, "oak" + sinuata, species epithet from nominative feminine singular of Latin sinuatus [12] , participle of sinuo, "to bend or bow out in curves" [13] + var. (variety or varietas) sinuata, to distinguish this taxon from the generally more shallowly lobed variety of this species, var. breviloba) is an infraspecific scientific name inspired by the wavy leaf margins characteristic of the taxon.
The common English word "oak," designating a shrub or tree of the genus Quercus, descends from the Proto-Germanic *eiks through the Old English ac, "oak tree," and the Middle English oke. [14] "Durand" honors Philadelphia botanist Elias Durand. [11] [15]
The Durand oak grows in low, wet areas of Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina and Texas in the southern United States. [16] [17]
The largest known Durand oak in the United States appeared on the National Register of Champion Trees in 2020. Located in Greene County, Alabama, the national champion specimen of Quercus sinuata var. sinuata was nominated in 2020 by Steve Gardiner and crowned on September 27, 2020, when it was last measured. By that time, the champion tree had attained a trunk circumference of 4.6 metres (180 inches), a height of 27 m (90 feet) and a crown spread of 29 m (95 ft). [6] The American Forests formula for assigning point scores to nominated trees, Trunk Circumference (in inches) + Height (in feet) + 1⁄4 Average Crown Spread (in feet), resulted in an overall score of 294 points.

Trillium erectum, the red trillium, also known as wake robin, purple trillium, bethroot, or stinking benjamin, is a species of flowering plant in the family Melanthiaceae. The plant takes its common name "wake robin" by analogy with the European robin, which has a red breast heralding spring. Likewise Trillium erectum is a spring ephemeral plant whose life-cycle is synchronized with that of the forests in which it lives. It is native to the eastern United States and eastern Canada from northern Georgia to Quebec and New Brunswick.
Quercus marilandica, the blackjack oak, is a small oak, one of the red oak group Quercus sect. Lobatae. It is native to the eastern and central United States.
Quercus virginiana, also known as the southern live oak, is an evergreen oak tree endemic to the Southeastern United States. Though many other species are loosely called live oak, the southern live oak is particularly iconic of the Old South. Many very large and old specimens of live oak can be found today in the Deep South region of the United States.
Quercus macrocarpa, the bur oak or burr oak, is a species of oak tree native to eastern North America. It is in the white oak section, Quercus sect. Quercus, and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak, and are important food for wildlife.
Quercus laevis, the turkey oak, is a member of the red oak group of oaks. It is native to the southeastern United States. The name turkey oak derives from the resemblance of the leaves to a turkey's foot. A Turkish and southern European species Quercus cerris is also commonly referred to as Turkey oak, so Quercus laevis is sometimes referred to as American turkey oak to distinguish it from the European species.
Quercus stellata, the post oak or iron oak, is a North American species of oak in the white oak section. It is a slow-growing oak that lives in dry areas on the edges of fields, tops of ridges also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations occur.
Quercus wislizeni, known by the common name interior live oak, is an evergreen oak, highly variable and often shrubby, found in many areas of California in the United States continuing south into northern Baja California in Mexico. It generally occurs in foothills, being most abundant in the lower elevations of the Sierra Nevada, but also widespread in the Pacific Coast Ranges—where since 1980 it has been known as a separate species Quercus parvula—and the San Gabriel Mountains. It was named for its collector, Friedrich Adolph Wislizenus (1810–1889).
Quercus fusiformis, commonly known as escarpment live oak, plateau live oak, plateau oak, or Texas live oak, is an evergreen or nearly evergreen tree. Its native range includes the Quartz Mountains and Wichita Mountains in southwestern Oklahoma, through Texas, to the Mexican states of Coahuila, Tamaulipas, and Nuevo León.
A clonal colony or genet is a group of genetically identical individuals, such as plants, fungi, or bacteria, that have grown in a given location, all originating vegetatively, not sexually, from a single ancestor. In plants, an individual in such a population is referred to as a ramet. In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil. Clonal colonies are common in many plant species. Although many plants reproduce sexually through the production of seed, reproduction occurs by underground stolons or rhizomes in some plants. Above ground, these plants most often appear to be distinct individuals, but underground they remain interconnected and are all clones of the same plant. However, it is not always easy to recognize a clonal colony especially if it spreads underground and is also sexually reproducing.
The Donald E. Davis Arboretum, in Auburn, Alabama, United States, is a public native plants museum, and botanical arboretum with educational facilities, event spaces, and a conservation program. Its grounds, covering 13.5 acres of Auburn University's campus, include cataloged living collections of associated tree and plant communities representative of Alabama's ecosystems, among which is mixed oak forest, carnivorous bog, and longleaf pine savanna. The living collections include more than 1,000 plant types, including 500 different plant species, with over 3,000 cataloged specimens. The Arboretum contains over a mile (2 km) of interwoven walking trails that meander through various southeastern biotopes.
Quercus coccinea, the scarlet oak, is a deciduous tree in the red oak section Lobatae of the genus Quercus, in the family Fagaceae.
Tiarella cordifolia, the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name cordifolia means "with heart-shaped leaves", a characteristic shared by all taxa of Tiarella in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort.
Quercus austrina, the bastard white oak or bluff oak, is an oak species that is endemic to the southeastern United States from Mississippi to the Carolinas, with a few isolated populations in Arkansas.
Carya myristiciformis, the nutmeg hickory, a tree of the Juglandaceae or walnut family, also called swamp hickory or bitter water hickory, is found as small, possibly relict populations across the Southern United States and in northern Mexico on rich moist soils of higher bottom lands and stream banks. Little is known of the growth rate of nutmeg hickory. Logs and lumber are sold mixed with other hickories. The nuts are an oil-rich food for wildlife.
Quercus buckleyi, commonly known as Texas red oak, Buckley's oak, or Spanish oak is a species of flowering plant. It is endemic to the southern Great Plains of the United States.
Quercus oglethorpensis is a species of plant in the beech family. It is endemic to the United States. It is named for Oglethorpe County, Georgia, where it was first discovered. The county, in turn, is named for James Oglethorpe, the founder of Georgia Colony in the 18th century.
Quercus pagoda, the cherrybark oak, is one of the most highly valued red oaks in the southern United States. It is larger and better formed than southern red oak and commonly grows on more moist sites. Its strong wood and straight form make it an excellent timber tree. Many wildlife species use its acorns as food, and cherrybark oak makes a fine shade tree. Cherrybark oak was formerly considered to be a subspecies of southern red oak, Quercus falcata, subsp pagodifolia.
Quercus sinuatavar. breviloba, commonly called Bigelow oak or Bigelow's oak, is a variety of Quercus sinuata, a species of oak tree that grows in parts of the southern United States and northeastern Mexico. Common names for this taxon are shallow-lobed oak, white shin oak, scaly-bark oak, limestone Durand oak, and shortlobe oak. The less specific common name bastard oak may refer to either of the two varieties of Quercus sinuata, var. sinuata and var. breviloba. Other common names include scrub oak or shin oak, but these names may refer to a number of other low growing, clump forming oak species, subspecies or varieties. For clear differentiation in common reference, American Forests uses Durand Oak to mean Quercus sinuata var. sinuata and Bigelow oak to mean Quercus sinuata var. breviloba, a shrubby variety of Quercus sinuata distinguished in part by its habit of forming clonal colonies in parts of its range.
The Alabama Champion Tree Program is a listing of the largest known specimens of particular tree species, native or introduced, in the U.S. state of Alabama. It was established in 1970 by the Alabama Forestry Commission. The program was modeled on the National Register of Big Trees, started by the American Forests organization in 1940. The goal of Alabama's program is to record, heighten awareness of, and preserve the largest tree specimens in the state. It uses the same formula for recording tree specimens that was developed by American Forests. Former champions are removed from the list as new, larger, champions are identified and recorded. Although introduced species that have naturalized are generally eligible for the program, those species that the Alabama Invasive Plant Council considers to be invasive were removed from the listing in 2011 and are no longer eligible. With the addition of 20 new specimens in 2011, the program had a total of 159 Champion Trees listed.
Quercus sinuata is a species of oak comprising two distinct varieties, Quercus sinuata var. breviloba and Quercus sinuata var. sinuata, occurring in southeast North America.
