Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass.
Oryzopsis hymenoides is a cool-season, perennial bunchgrass with narrow, rolled leaf blades. It is native to western North America east of the Cascades from British Columbia and Alberta south to southern California, northeastern Mexico, and Texas.
Andropogon gerardi, commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot.
Setosphaeria turcica is the causal agent of northern corn leaf blight in maize. It is a serious fungal disease prevalent in cooler climates and tropical highlands wherever corn is grown. It is characterized by large cigar shaped necrotic lesions that develop on the leaves due to the polyketide metabolite monocerin.
Maize, also known as corn, is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that when fertilized yield kernels or seeds, which are fruits.
Tripsacum dactyloides, commonly called eastern gamagrass, or Fakahatchee grass, is a warm-season, sod-forming bunch grass. It is widespread in the Western Hemisphere, native from the eastern United States to northern South America. Its natural habitat is in sunny moist areas, such as along watercourses and in wet prairies. In some areas, it has adapted well to disturbed conditions.
Puccinellia distans is a species of grass known by the common names weeping alkaligrass and European alkali grass. It is native to Europe and it is present in most of North America, where it is perhaps an introduced species. It grows in moist habitat, usually in areas with saline soils, such as the edges of salted roads. It is a perennial herb producing hollow stems up to 40 to 60 centimeters in maximum height. The inflorescence is a spreading array of branches, the lower ones reflexed. The branches bear several rough-haired spikelets containing flowers.
Puccinellia howellii is a rare species of grass known by the common name Howell's alkaligrass. It is endemic to Shasta County, California, where it is known from a single population in Whiskeytown National Recreation Area near Whiskeytown. Its entire population is contained in a 1-acre (4,000 m2) complex of three saline mineral springs directly next to Highway 299. The grass was first described to science in 1990 and no other populations were discovered despite extensive searches of the area.
Setaria verticillata is a species of grass known by the common names hooked bristlegrass, rough bristle-grass and bristly foxtail. It is native to Europe, but it is known on most continents as an introduced species and often a noxious weed. It is a hardy bunchgrass which grows in many types of urban, cultivated, and disturbed habitat. It is a weed of many types of agricultural crops, growing in vineyards and fields. Herbicide-resistant strains have been noted.
Urena lobata, commonly known as Caesarweed or Congo jute, is a tender perennial, variable, erect, ascendant shrub or subshrub measuring up to 0.5 meters (1.6 ft) to 2.5 meters (8.2 ft) tall. The stems are covered with minute, star-like hairs and often tinged purple. Considered a weed, it is widely distributed in the tropics, including in Brazil and Southeast Asia.
Muhlenbergia racemosa is a species of grass known by the common names green muhly and marsh muhly. It is native to North America, where it is most common in the north-central United States. It also occurs in the western United States and northern Mexico.
Panicum repens is a species of grass known by many common names, including torpedograss, 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."
Ctenium aromaticum is a species of grass known by the common name toothache grass. It is native to the southeastern United States, where it grows on the coastal plain.
Paspalum floridanum is a species of grass known by the common name Florida paspalum. It is native to the eastern United States.
Setaria parviflora is a species of grass known by the common names marsh bristlegrass, knotroot bristle-grass, bristly foxtail and yellow bristlegrass. It is native to North America, including Mexico and the United States from California to the East Coast, Central America and the West Indies, and South America.
Setaria palmifolia is a species of grass known by the common names palmgrass, highland pitpit, hailans pitpit, short pitpit, broadleaved bristlegrass, and knotroot. In Spanish it is called pasto de palma and in Samoan vao 'ofe 'ofe. It is native to temperate and tropical Asia. It is known elsewhere as an introduced, and often invasive, species, including in Australia, New Zealand, many Pacific Islands, and the Americas.
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.
Leersia hexandra is a species of grass known by the common names southern cutgrass, clubhead cutgrass, and swamp rice grass. It has a pantropical distribution. It is also an introduced species in many regions, sometimes becoming invasive, and it is an agricultural weed of various crops, especially rice. It is also cultivated as a forage for livestock.
Brachiaria mutica is a species of grass known by the common names para grass, buffalo grass, Mauritius signal grass, pasto pare, malojilla, gramalote, parana, Carib grass, and Scotch grass. Despite its common name California grass, it does not occur in California; it is native to northern and central Africa and parts of the Middle East, where it is cultivated for fodder. It was introduced elsewhere and it is now cultivated throughout tropical regions of the world for this purpose.
Northern corn leaf blight (NCLB) or Turcicum leaf blight (TLB) is a foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria turcica. With its characteristic cigar-shaped lesions, this disease can cause significant yield loss in susceptible corn hybrids.
