Swamp Chestnut Oak (Quercus michauxii) vs. Chinquapin Oak (Quercus muehlenbergii)
Updated January 6th, 2021These two species are sometimes confused where their ranges overlap, due to similar leaf shape, bark, and acorns. They can be distinguished by close examination of the leaves, acorn cap scales, and buds. Swamp Chestnut oak is usually limited to acidic soils and moister habitats, and ranges farther south, whereas Chinquapin oak prefers calcium-rich soils that are less acidic, can grow on much drier sites, and ranges much farther north and west.
