Chinkapin Oak - Southwestern Form
Here are leaves of Quercus muehlenbergii from the discontinuous portion of the Chinkapin Oak range. These areas are notably more arid than the areas of the primary range, and has resulted in the evolution of trees quite distinct from the primary range species, with leaves smaller, more blue-hued in color, and with a thicker waxy cuticle, to retard evapotranspiration during high heat events. As with other trees, it appears the waxy cuticle is sufficient to largely discourage fungal colonization of the leaves.
