Quercus havardii

Wikidata reference: Q4112174

Quercus havardii (common names include shinnery oak, shin oak and Havard oak) is a deciduous, low-growing, thicket-forming shrub that occupies some two million to three million hectares (7,700 to 11,600 square miles) in the southern Great Plains of North America. Clones may reach hundreds to thousands of years old, although aboveground stems typically live only 11 to 15 years. Shinnery oak stems are usually 1 to 2 metres (3 feet 3 inches to 6 feet 7 inches) tall and codominate the plant community with mid- and tall-grasses, which are usually taller than the oaks.
The specific epithet honors U.S. Army surgeon and botanist Valery Havard, who contributed much to the knowledge of southwestern plants. The word "shinnery" seems to be derived from chêne (French for oak), and not from the height of the plant.
