Field Guide

Its range and interesting, variable leaf shapes identify water oak. Like many species that require wet lowland forests, water oak has been declining in our state due to long-term extensive disruption of natural habitats in our Bootheel counties.

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.

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.

Our state flower, the hawthorn, is solidly represented in Missouri. There are about 100 different kinds of hawthorns that occupy almost every kind of soil in every part of the state. These members of the rose family are closely related to apples.

Red mulberry is native to Missouri and North America. You can distinguish it from the introduced white mulberry tree, which is a noxious weed, by its leaves and fruits.

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.

Ozark witch-hazel is a large native shrub that grows along dry, rocky streambeds in southern and east-central Missouri. The yellow, ribbonlike flowers bloom as early as January. In the fall, the seeds are ejected forcefully, to a distance of up to 30 feet!

Poison ivy is a toxic plant that contains an oil in all its parts that, if you come into contact with it, can cause an intense skin reaction. Learn to recognize it, and sidestep it on your outings.
