Digitaria ischaemum is a species of crabgrass known by the common names smooth crabgrass and small crabgrass. It is native to Europe and Asia, but it is known throughout much of the warm temperate world as an introduced species and often a common roadside and garden weed.

Panicum repens is a species of grass known by many common names, including torpedo grass, creeping panic, panic rampant, couch panicum, wainaku grass, quack grass, dog-tooth grass, and bullet grass. Its exact native range is obscure. Sources suggest that the grass is native to "Africa and/or Asia", "Europe or Australia", "Eurasia", "Australia", "Europe, Asia, and Africa", or other specific regions, including the Mediterranean, Israel, and Argentina. It is present in many places as an introduced species and often a noxious weed. It has been called "one of the world's worst weeds."

It is native to Mauritius, Réunion, parts of mainland Africa, and Madagascar. It has been introduced widely outside its native range, mainly for use as a pasture and turf grass. It has naturalized in some regions.
Alysicarpus vaginalis is a species of flowering plant in the legume family, Fabaceae. It is native to parts of Africa and Asia, and it has been introduced to other continents, such as Australia and the Americas. It is cultivated as a fodder for livestock, for erosion control, and as a green manure. Common names include alyce clover, buffalo clover, buffalo-bur, one-leaf clover, and white moneywort.
Digitaria eriantha, commonly known as digitgrass or Pangola-grass, is a grass grown in tropical and subtropical climates. It grows relatively well in various soils, but grows especially well in moist soils. It is tolerant to droughts, water lodging, suppresses weeds and grows relatively quickly after grazing. This grass demonstrates great potential for farmers in Africa in subtropical and tropical climates, mostly for livestock feed.
Digitaria insularis is a species of grass commonly known as sourgrass. It is native to Central and South America and the southern parts of the United States and has been introduced into other parts of the world. It was first described by the German botanist Friedrich Karl Georg Fedde in 1904.
