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.

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.

Pin oak is one of the easiest trees to recognize by its shape alone: It has a tall, straight trunk, an overall pyramidal or conical shape and, most notably, the branches on the lower third of the tree angle downward.

An attractive shrub with wide-spreading, graceful, recurved branches and bark peeling off in conspicuous thin strips, ninebark is found throughout southern and eastern Missouri on gravel bars, rocky stream banks, and bluffs along streams. It's very popular as a native landscaping shrub, too.
