Comments: Common along the Atlantic Coast, marram grass is a treat in Indiana beeches stabilizing and forming new dunes. Marram grass is threatened by the introduced, ornamental lyme grass. They differ in that lyme grass has a distinct blue-green color whereas marram grass is completely green.
Etymology: The genus name comes from the Greek word, ámmos, which means "sand" and, philos, which means "friend of" or "fond of". The epithet is derived from the two words brevi- which means "short" and ligulata meaning "tongue form" referring to its ligule.
