Field Guide

American basswood is a common shade tree planted in lawns, parks, and along city streets. Recognize it by its leaf shape and texture, and by the unusual strap-shaped, reduced leaf attached to the clusters of small flowers.

Easily Missouri’s most valuable tree, the black walnut provides the finest wood in the world, as well as delicious nuts. Both are in high demand and thus form an important part of Missouri’s economy.

Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

Shellbark hickory is the largest of the true hickories and has the best-tasting hickory nuts in Missouri. Compared to shagbark hickory, it has larger leaves and more leaflets, plus larger nuts and orange twigs.

Black hickory's nut, like that of the pignut hickory, is awfully hard to crack. Because rural Ozarkers noticed their hogs had no trouble extracting the sweet kernels, both species came to be called "pignut hickories."

A rugged tree of dry upland forests in the eastern Ozarks, the pignut hickory has pear-shaped fruits with thin husks. Settlers were unimpressed with the nuts’ flavor and fed them to their hogs!

The pecan, a type of hickory, is one of Missouri’s favorite nut trees. Originally pecan had a fairly limited, southern distribution, but today it is found in and out of cultivation nearly statewide, owing to the popularity of the nuts.

Swamp chestnut oak grows in Missouri's Bootheel swamps. The leaves look something like those of true chestnut trees.

American hazelnut is a thicket-forming shrub that grows to about 10 feet high. It is prized for its edible nuts, which are covered by a distinctive leafy or papery, jagged-edged bract.
