Dichanthelium clandestinum is a species of grass known by the common name deertongue.

[1][2] This species is a rhizomatous perennial grass forming clumps of hairy stems up to 1.4 meters tall.

Each is up to 25 centimeters long by 3 wide, lance-shaped, sometimes rigid, and hairless to slightly hairy.

[2] The seeds of deertongue attract many types of birds, such as turkeys.

The grass is not considered a good forage for livestock because it is low in nutrients.
