Field Guide

Cupseed is a relatively stout, robust twining vine that dies back to the ground in severe winters. It is scattered south of the Missouri River. It bears clusters of black fruits. The seeds are shaped like little cups.

Common prickly ash is a thicket-forming shrub or small tree. Its compound leaves resemble of those of ash trees, but it’s in a different family. Pairs of stout, curved prickles occur at each node. Scattered statewide, but less common in the Ozarks.

White fringe tree is a shrub or small tree that is native to southwest and southeast Missouri. Its fragrant, showy clusters of white, drooping, fringe-like flowers make it a popular for landscaping.

Eastern leatherwood is a native shrub of bottomlands, stream banks, and bases of bluffs. It has unusual little dangling yellow flowers, and its twigs are surprisingly flexible.

Four species of privets occur in Missouri, all are nonnative, and all are considered invasive or potentially invasive. When they invade natural habitats, they can form dense thickets that crowd out native vegetation.

Swamp privet is a straggly shrub or small tree growing in wet to swampy ground. It is quite noticeable in early spring, with the clusters of yellow flowers and bracts appearing along the gray branches before the leaves come out. In this way, it is similar in aspect to spicebush.

Water tupelo, or tupelo gum, is a large tree with a large, swollen, sometimes buttressed base, a tapering trunk, and a flattened, spreading crown. It and bald cypress are the dominant trees in Missouri’s Bootheel swamps.
