Fonio, also sometimes called findi or acha, is the term for two cultivated grasses in the genus Digitaria that are important crops in parts of West Africa. The nutritious food with a favorable taste is a vital food source in many rural areas, especially in the mountains of Fouta Djalon, Guinea, but it is also cultivated in Mali, Burkina Faso, Ivory Coast, Nigeria, and Senegal. The global fonio market was estimated at 721,400 tonnes in 2020. Guinea annually produces the most fonio in the world, accounting for over 75% of the world's production in 2019. The name fonio is from Wolof foño. In West Africa, the species black fonio (Digitaria iburua) and white fonio (Digitaria exilis) are cultivated; the latter is the economically more important crop.
Calamagrostis is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of Calamagrostis generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like.
Agrostis is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world. It has been bred as a GMO creeping bent grass.
Digitaria exilis, referred to as findi or fundi in areas of Africa, such as The Gambia, with English common names white fonio, fonio millet, and hungry rice or acha rice, is a grass species. It is the most important of a diverse group of wild and domesticated Digitaria species known as fonio that are harvested in the savannas of West Africa. The grains are very small. It has potential to improve nutrition, boost food security, foster rural development and support sustainable use of the land. Despite its valuable characteristics and widespread cultivation, fonio has generally received limited research and development attention, which is also why the species is sometimes referred to as an underutilized crop.
Deschampsia is a genus of plants in the grass family, commonly known as hair grass or tussock grass. The genus is widespread across many countries.
Helictotrichon, or alpine oatgrass, is a genus of perennial flowering plants in the grass family. The genus name comes from the Greek heliktos meaning twisted, and trichos meaning hair, referring to the shape of the awn.
Setaria is a widespread genus of plants in the grass family. The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.
Axonopus is a genus of plants in the grass family, known generally as carpet grass. They are native primarily to the tropical and subtropical regions of the Americas with one species in tropical Africa and another on Easter Island. They are sometimes rhizomatous and many are tolerant of periodic submersion.
Digitaria sanguinalis is a species of grass known by several common names, including hairy crabgrass, hairy finger-grass, large crabgrass, crab finger grass, purple crabgrass. It is one of the better-known species of the genus Digitaria, and one that is known nearly worldwide as a common weed. It is used as animal fodder, and the seeds are edible and have been used as a grain in Germany and especially Poland, where it is sometimes cultivated. This has earned it the name Polish millet.
Digitaria compacta is a grass species native to India and Indochina. It is cultivated in the Khasi Hills of northeast India, used as a glutinous flour for making bread or porridge, and known as raishan.
