Muhlenbergia minutissima is a species of grass known by the common name annual muhly. It is native to North America.
It is found throughout the western United States and much of Mexico. It can be found in many habitat types, including disturbed areas.
It is an annual bunchgrass growing 30 centimeters tall. The inflorescence is an open, spreading array of hair-thin branches bearing millimeter-long spikelets.
Eleusine indica, the Indian goosegrass, yard-grass, goosegrass, wiregrass, or crowfootgrass, is a species of grass in the family Poaceae. It is a small annual grass distributed throughout the warmer areas of the world to about 50 degrees latitude. It is an invasive species in some areas.
Vulpia myuros, the annual fescue, or rat's-tail fescue, is an annual grass species of the genus Vulpia. It was probably originally native to Eurasia, but it can now be found nearly worldwide as a naturalized species.
Beckmannia is a small genus of grasses containing two species known generally as sloughgrass. Beckmannia eruciformis is a Eurasian perennial, and Beckmannia syzigachne is an annual grass found in North America and Asia. The genus was named for the German scientist Johann Beckmann.
Eragrostis hypnoides is a species of grass known by the common name teal lovegrass. It is native to the Americas from Canada to Argentina. It is found in moist areas near water in substrates of sand or mud.
Aira praecox is a species of grass known by several common names, including early hair-grass, yellow hairgrass and spike hairgrass. It is native to Europe, where it is found in dry, sandy places, on rocky outcrops, and in heath grassland. It also grows in North America as an introduced species, where it can be found on the east and west coasts in sandy or rocky areas, such as beaches and roadsides. This is a tuft-forming annual grass growing up to about 25 centimeters in maximum height. The thin, narrow leaves are located at the base of the stem, and are typically 0.3–2 millimeters wide. It bears very small inflorescences of purple-tinted green bisexual spikelets.
Briza minor is a species of grass known by the common names lesser quaking-grass or little quakinggrass. It is native to the Mediterranean Basin, and it is known elsewhere, including much of North America, as an introduced species. It is an annual grass producing narrow clumps of erect stems up to 50 centimeters tall. The inflorescence bears several small cone-shaped spikelets, each hanging on a pedicel.
Panicum capillare, known by the common name witchgrass, is a species of grass. It is native plant to most of North America from the East Coast through all of the West Coast and California. It can be found as an introduced species in Eurasia, and as a weed in gardens and landscaped areas. It grows in many types of habitat.
Crypsis vaginiflora is a species of grass known by the common name modest pricklegrass. It is native to North Africa but it can be found in other parts of the world as an introduced species, including the western United States, particularly California, where it is common in wet habitat such as vernal pools. It is an annual grass forming mats of green, prostrate stems not generally exceeding 30 centimeters long. The stems are enveloped in the sheaths of the leaves, the small blades of which break off. The inflorescence is a dense panicle usually no more than 1.5 centimeters long tucked into the sheaths of the uppermost leaves.
Cynosurus echinatus is a species of grass known by the common names bristly dogstail grass, rough dog's-tail and hedgehog dogtail. It is native to southern Europe, and it is known in the Americas and Australia as an introduced species and sometimes a noxious weed. An herbicide-resistant strain can be found growing as a weed in canola and wheat fields in Chile. This is an annual grass growing 10 to 50 centimeters tall. The inflorescence is a rounded or oval cluster or series of clusters of spikelets. The fertile spikelet has an awn up to a centimeter long. The awns clumped closely together into a tuft gives the inflorescence its bristly, hairy appearance.
Polypogon monspeliensis, commonly known as annual beard-grass or annual rabbitsfoot grass, is a species of grass. It is native to southern Europe, but it can be found today throughout the world as an introduced species and sometimes a noxious weed. It is an annual grass growing to heights between 5 centimeters and one meter. The soft, fluffy inflorescence is a dense, greenish, plumelike panicle, sometimes divided into lobes. The spikelets have long, thin, whitish awns, which give the inflorescence its texture.
Muhlenbergia microsperma is a species of grass known by the common name littleseed muhly. It is native to the Americas from the Southwestern United States and California through Central America into Peru and Venezuela.
Panicum dichotomiflorum, known by the common names fall panicgrass, autumn millet, and fall panicum is a species of Poaceae "true grass". It is native to much of the eastern United States and parts of Canada, and it can be found in the Western United States through California. It may be an introduced species in some western climates. It grows in many types of habitat, including disturbed areas and chaparral habitats.
Pennisetum villosum is a species of flowering plant in the grass family Poaceae, known by the common name feathertop grass or just feathertop. It is native to northeastern Africa and parts of the Arabian Peninsula, and it is grown elsewhere as an ornamental plant. It can sometimes be found growing wild where it has escape cultivation. This is a perennial grass growing in rhizomatous clumps, producing erect stems up to about 75 centimeters tall. The inflorescence is a panicle of clustered spikelets surrounded by a cloudlike mass of plumose white bristles up to 5 centimeters long.
Melinis repens is a species of grass known by the common names rose Natal grass, Natal red top, or simply Natal grass. It is native to southern Africa and an introduced species, often considered a noxious weed, on other continents such as North America and Australia. It is an annual or perennial grass, growing up to a meter tall. Its growth rate is dependent on temperature. The inflorescence is an open array of branches bearing spikelets densely coated in silky white or pink hairs.
Phalaris caroliniana is a species of grass known as Carolina canarygrass and maygrass. It is native to the southern United States, and it can be found as a naturalized species along the west coast of the United States, as well as northern Mexico and parts of Europe and Australia. It is most often found in moist to wet habitats, such as marshy meadows, and it can thrive in disturbed areas. It is an annual grass reaching a maximum height between 1 and 1.5 m. The hairy inflorescence is roughly oval in shape and up to 7 cm (2.8 in) long by 2 cm (0.79 in) wide.
Phalaris lemmonii is an uncommon species of grass known by the common name Lemmon's canarygrass. It is endemic to California, where it can be found in coastal and inland mountain ranges and the Central Valley.
Poa infirma is a species of grass known by the common names early meadow-grass and weak bluegrass. It was first described from a specimen found in Colombia, but it is actually an introduced species in the Americas and is native to Europe. It grows in many types of habitat, including disturbed areas. It is very similar to Poa annua, which is probably a daughter species, and it is often mistaken for P. annua unless it is closely examined.
Polypogon maritimus is a species of grass known by the common names Mediterranean beard grass and Mediterranean rabbitsfoot grass. It is native to the Mediterranean Basin. It is also known in other parts of the world, including Australia, New Zealand, and the United States, as an introduced species that can be found in moist habitat types. It is an annual grass producing stems up to half a meter tall. The inflorescence is a plumelike panicle up to 15 centimeters long containing many V-shaped spikelets with long awns.
Sporobolus flexuosus is a species of grass known by the common name mesa dropseed. It is native to western North America, where it can be found in the deserts and woodlands of the Southwestern United States and Northern Mexico.
Ventenata dubia is a species of grass known by the common names North Africa grass and wiregrass. It is native to southern Europe, North Africa and the Middle East. It is becoming well known in North America, where it is an introduced species and a noxious weed of cultivated and disturbed habitat. It is problematic in the Pacific Northwest, where it was first identified in Washington in 1952 and Idaho in 1957. It was found in Utah in 1996. It probably spreads when it gets mixed in with grass seed and is transported and inadvertently planted.
