Browngrass

This large, brown grass grows up to 4 feet (1.2 meters) tall. The long, narrow stalks grow in sparse patches that are light and frail.

When mature, the end of the stem eventually transforms into a large, light brown spikelet.

During the early autumn, it produces excessive amounts of pollen,but it does not cause many allergic reactions, and after flowering, it is left with a few tiny grains.
