Calamovilfa gigantea
Calamovilfa gigantea is a species of grass known by the common name giant sandreed. It is native to the Rocky Mountains and Great Plains of the United States. Description
This perennial grass has a long rhizome coated with scalelike leaves. The stems can reach 2.5 meters tall. The leaf blades may reach 90 centimeters in length. The inflorescence is a panicle up to 80 centimeters long by 60 wide, with spreading branches. This grass grows in sandy areas, including blowouts.
