Field Guide

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.

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.

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.

Chinkapin oak is fairly easy to identify because of its distinctively toothed leaves. Look for it growing in rocky soils derived from limestone or dolomite on bluffs and in upland woods, and in floodplain forests and lower slopes along streams.

A very small shrub of our native prairies and other open sites, New Jersey tea was used by patriotic American colonists as a substitute for black tea imported from England during the Revolutionary War.

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.
