Eragrostis cilianensis is a species of grass known by several common names, including stinkgrass, candy grass, and gray lovegrass.
Festuca idahoensis is a species of grass known by the common names Idaho fescue and blue bunchgrass. It is native to western North America, where it is widespread and common. It can be found in many ecosystems, from shady forests to open plains grasslands.
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.
Parapholis incurva is a species of grass native to Europe, Asia and northern Africa, and widely naturalised elsewhere. Common names include coast barbgrass, curved sea hard grass, curved hard-grass, sicklegrass, curved sicklegrass and curved parapholis.
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.
Paspalum dilatatum is a species of grass known by the common name dallisgrass, Dallas grass, or sticky heads. It is native to Brazil and Argentina, but it is known throughout the world as an introduced species and at times a common weed. Its rapid growth and spreading rhizomes make it an invasive pest in some areas. It is present in the southern half of North America, southern Europe, much of Africa, Australia, New Zealand, and many tropical and subtropical areas.
Paspalum distichum is a species of grass. Common names include knotgrass, water finger-grass, couch paspalum, eternity grass, gingergrass, and Thompson grass. Its native range is obscure because it has long been present on most continents, and in most areas it is certainly an introduced species. Its native range probably includes parts of the tropical Americas.
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.
Poa bulbosa is a species of grass known by the common names bulbous bluegrass or bulbous meadow-grass. It is native to Eurasia and North Africa, but it is present practically worldwide as an introduced species. It is widespread in the United States and southern Canada. It was introduced to the eastern United States around 1906 and the western US in 1915 as a contaminant in shipments of alfalfa seed. It was intentionally planted on both the east and west coasts to control weeds and prevent erosion. Today it is a common grass across the continent and is a noxious weed in some areas. It is a sturdy, hardy, persistent, aggressive grass that easily outcompetes many other plants and becomes the dominant species in disturbed habitat types, such as overgrazed fields.
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.
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.
Tripidium ravennae, synonym Saccharum ravennae, with the common names ravennagrass and elephant grass, is a species of grass in the genus Tripidium. It is native to southern Europe, western Asia and South Asia and is known in North America as an introduced species, where it is sometimes an invasive and troublesome noxious weed.
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.
