Digitaria cognata is a species of grass known by the common names fall witchgrass, [2] Carolina crabgrass, [3] and mountain hairgrass. [4]
This grass is a perennial without rhizomes. The roots are shallow. The erect stems grow up to 56 centimeters tall. The stem bases are tough and hairy. [2] The leaves are up to 12.6 centimeters long. [5] They are narrow, with "one side wavy, and the other smooth". [3] The inflorescence is a purple-tinged panicle with single-flowered spikelets. [3]
This grass provides graze for livestock and wild ungulates, and birds eat the seeds. [3]
Digitaria is a genus of plants in the grass family native to tropical and warm temperate regions but can occur in tropical, subtropical, and cooler temperate regions as well. Common names include crabgrass, finger-grass, and fonio. They are slender monocotyledonous annual and perennial lawn, pasture, and forage plants; some are often considered lawn pests. Digitus is the Latin word for "finger", and they are distinguished by the long, finger-like inflorescences they produce.
