Grasses
All true grasses (species in the grass family)
Missouri has 276 species in the grass family, including well-known crop plants and our native prairie grasses. Distinguishing between the species can be difficult, but it’s easy to learn some basics about the group.

Sedges
Carex, Schoenoplectus, Scirpus, and other genera
Missouri has more than 200 species in the sedge family. Distinguishing between these grasslike plants can be difficult, but it’s easy to learn some basics about the group.

Bromus pubescens (formerly B. purgans)
Several species of brome grasses are found in Missouri. Canada brome, or hairy woodland brome, is one of the few that are native. It grows to 4 feet high, and its open flower clusters have drooping spikelets.

Poverty Grass (Curly Oat Grass)
Danthonia spicata

About Wildflowers, Grasses and Other Nonwoody Plants in Missouri

A very simple way of thinking about the green world is to divide the vascular plants into two groups: woody and nonwoody (or herbaceous). But this is an artificial division; many plant families include some species that are woody and some that are not. The diversity of nonwoody vascular plants is staggering! Think of all the ferns, grasses, sedges, lilies, peas, sunflowers, nightshades, milkweeds, mustards, mints, and mallows — weeds and wildflowers — and many more!
