Quercus welshii, the wavy leaf oak, shinnery oak, or Tucker oak, is a North American species of shrub in the (beech family) found in the Colorado Plateau and Canyonlands region of the southwestern United States.[3]:143
Description
Growth pattern
Quercus welshii is a deciduous shrub 2 to 6 feet (0.61 to 1.83 meters) tall.[3]:143
Roots, stems, and leaves
The plant has an elaborate root system, anchoring it in sandy soils and helping stabilize soils in sandy desert scrub communities.[3]:143
The leaves are elliptical or lance-shaped with 6–10 lobes along the margins and pointed tips, sometimes with lobes and teeth.[3]:143
The leaves are up to 1⁄2 to 2 in (1.3 to 5.1 cm) long with dense hairs on both sides, becoming smooth with age.[3]:143
Inflorescence and fruit
Quercus welshii blooms from March to June.[3]:143
Male and female flowers are in separate hanging clusters.[3]:143
Acorns are 1⁄2 to 3⁄4 in (13 to 19 millimeters) long.[3]:143
Taxonomy
The species was first described by Stanley Larson Welsh in 1986 as Quercus havardii var. tuckeri. It was raised to a full species by R.A. Denham in 2003 using the replacement name Quercus welshii,[4] named after Welsh,[3]:143 as the name Quercus tuckeri had already been used for a fossil species.[5] Quercus welshii has been included within Quercus havardii, but both morphological and molecular evidence suggests that it is distinct.[6] Quercus welshii is not included in a 2017 list of Quercus species by subgenus and section, but Quercus havardii is placed in Quercus sect. Quercus.[7]
Distribution and habitat
Quercus welshii can be found in sand desert shrub communities, and sandy soils of blackbrush scrub and pinyon–juniper woodland communities in Arizona, Utah, western Colorado, and northwestern New Mexico.[3]:143[8]
