Field Guide

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.

A beautiful tree, swamp white oak features bicolored leaves that are shiny, dark green above and downy white below. When a breeze sets them in motion, their wavy or lobed shapes add a calm grace to a summer's hike.

Scarlet oak is a common tree of the Missouri Ozarks. Today it occupies much the same area that shortleaf pine used to dominate before it was extensively cut prior to the 1920s.

Found throughout Missouri and in all kinds of habitats, the white oak is one of our most attractive, long-lived, and stately shade trees. Learn to recognize it by its light gray bark, rounded-lobed leaves, and distinctive acorns.

Sassafras, with its aromatic oval, mitten- , and trident-shaped leaves, is rich in both human and natural history, and it can be a spectacular tree for fall color.

White mulberry was introduced from Asia for its berries and as fodder for an attempted silkworm industry. Birds have helped spread white mulberry so much that in many places it is more common than our native red mulberry.

The white, smooth-looking limbs of sycamore rise over countless streams and river banks, as well as over sidewalks and city streets. The leaves, which somewhat resemble those of maples, can reach remarkably large sizes.

Red maple is one of our most useful — and beautiful — native trees. You can find it in the woods as well as in landscape plantings statewide. Many horticultural varieties are available at nurseries.

Sugar maple is a tree that inspires much “oohing and aahing” during fall color season. Its sap is famous as a source for maple syrup, but its use in landscaping and for furniture is also widespread.

A member of the maple family, box elder is often confused with poison ivy because its compound leaves sometimes grow in threes (though also in fives). A fast-growing tree, its winged seeds betray its relationship to other maples.
