Ozark Chinquapin Identification

Take a look at our look-likes page to see trees often mistaken for Ozark chinquapin


There is a lot of variation in leaves among populations and even on individual trees.  The Ozark chinquapin has leaves 5.5 to 9.25” long, with coarse teeth. They are often slightly more broad above the middle. Leaves are arranged in an alternate pattern.  Trees below the Arkansas River have smaller leaves. 


Each burr contains one nut. On rare occasions they can produce more than one nut. They are approximately 20 mm  long, and about 10mm wide. 


Clusters of  5-10 burrs are located about a foot away from the end of the branch because the tree continue to grow after flowering has occurred.


Blooms late May to early June. The trees are monoecious and self-incompatible; they require another tree for pollination. They are both wind and insect pollinated.


Ozark chinquapin trees are smooth when they are young and have silvery colored markings.  After about 13 years they develop flat broad ridges that are arranged parallel to one another.
