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.

Description

Quercus sinuata is a deciduous tree up to 20 metres (67 feet) tall. Leaves are narrow, with shallow rounded lobes. It tends to grow in wet habitats, such as on river bluffs, river bottoms, and flatwoods, and generally over basic substrates, such as mafic rocks, shells, or calcareous sediment. [3] [4]

There are two varieties, with morphologically intermediate forms sometimes occurring where their ranges overlap: [2] [3]

Common names

Perhaps arising from the classification challenges posed by a lack of morphological consistency among individuals of the species, the common name bastard oak [5] may refer to either var. sinuata or var. breviloba or to any of their intermediate forms. The common names Durand oak [3] and Durand white oak most often refer to Quercus sinuata var. sinuata. [6] Other common names for Quercus sinuata var. sinuata include bastard white oak and bluff oak, but these names more often refer to Quercus austrina . [7] Common names for Quercus sinuata var. breviloba are Bigelow oak, Bigelow's oak, shallow-lobed oak, white shin oak, scaly-bark oak, limestone Durand oak, and shortlobe oak. 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.

Distribution and habitat

Quercus sinuata var. breviloba is native to central and north central Texas, south central and southwest Oklahoma, and to Coahuila, Nuevo León, and Tamaulipas in northern Mexico. Quercus sinuata var. sinuata is native to the south-central and southeastern United States from central Texas and southwestern Arkansas to the Carolinas. [3] [8] Their respective ranges intersect in the Hill Country of central Texas, where streams flowing through dry, brushy limestone hills create a mosaic of wet and well drained habitats. [3]

<i>Quercus virginiana</i> Species of oak tree

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.

<i>Quercus macrocarpa</i> Species of oak tree

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.

<i>Quercus stellata</i> Species of oak tree

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, and also grows in poor soils, and is resistant to rot, fire, and drought. Interbreeding occurs among white oaks, thus many hybrid species combinations occur. It is identifiable by the rounded cross-like shape formed by the leaf lobes and hairy underside of the leaves.

<i>Tiarella cordifolia</i> Species of flowering plant

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.

<i>Tiarella</i> Genus of flowering plants in the family Saxifragaceae

Tiarella, the foamflowers, is a genus of flowering plants in the family Saxifragaceae. The generic name Tiarella means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. As of October 2022, the taxonomy of Tiarella in eastern North America is in flux.

<i>Quercus lyrata</i> Species of oak tree

Quercus lyrata, the overcup oak, is an oak in the white oak group. The common name, overcup oak, refers to its acorns that are mostly enclosed within the acorn cup. It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there. It is a slow-growing tree that often takes 25 to 30 years to mature. It has an estimated lifespan of 400 years.

<i>Quercus austrina</i> Species of oak tree

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.

<i>Quercus buckleyi</i> Species of oak tree

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.

<i>Ribes aureum</i> Species of plant

Ribes aureum, known by the common names golden currant, clove currant, pruterberry and buffalo currant, is a species of flowering plant in the genus Ribes native to North America.

<i>Quercus pagoda</i> Species of oak tree

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.

<i>Quercus sinuata <span style="font-style:normal;">var.</span> breviloba</i> Variety of a species of oak tree

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.
