Q. stellata is a perennial tree of the Fagaceae family native to North America. [2]


Q. stellata is found in the southeastern corner of the United States from Texas to Massachusetts. [2]



Q. stellata proliferates in uland forests and woodlands, especially in clay or rocky soils and in communities at least formerly exposed to fire. [1] Specimens have been taken from mesic woodland, pine-oak stands, hardwood forests, second growth woodland with sandy soil, open pine oak woodland, and old growth pineland. [3]


Q. stellata has been observed to flower March through May and in November. [4] Native, perennial tree to 75.0 feet. Bark usually gray to gray-brown, relatively thick, irregularly fissured with narrow or broad scaly ridges; leaves deciduous, alternate, simple, stellate-hairy on lower surface, usually 5-7 lobed (not bristle tipped), the upper 3 lobes usually being the largest, usually having somewhat of a crosslike appearance; plants monoecious; inflorescences are catkins; fruit is a 1-seeded nut called an acorn, 1-2 clustered, cup enclosing 33-50% of the nut, maturing the first year in the fall.
