Nerved Manna Grass

Nerved Manna GrassGlyceria nervata (Willd.) Trin.

Nerved Manna-grass usually precedes the other species by a fortnight, and is perhaps the most common in a majority of the states.

Growing luxuriantly in the borderland between pasture and marsh it furnishes an important part of the herbage of wet meadows, and, though it varies greatly in different soils, the gracefully drooping panicles may be recognized by their spreading and drooping branches and their tiny, purple and green spikelets.
