Crypsis alopecuroides is a species of grass known by the common name foxtail pricklegrass. It is native to Europe, the Middle East, and North Africa. It is also known in the western United States as a common and widespread introduced species, especially in sandy areas around water, such as lakesides. It has also been collected at shipping points near Philadelphia but has not been seen there in about a century. This is an annual grass producing mostly upright and unbranching stems, often dark in color, up to about 75 centimeters in maximum height. The green leaves are up to 12 centimeters long, sometimes waxy in texture. The inflorescence is a dense cylindrical panicle of tiny green to purple spikelets.
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.
Hyparrhenia hirta is a species of grass known by the common names common thatching grass and Coolatai grass. It is native to much of Africa and Eurasia, and it is known on other continents as an introduced species. In eastern Australia it is a tenacious noxious weed. In South Africa, where it is native, it is very common and one of the most widely used thatching grasses. It is also used for grazing livestock and weaving mats and baskets.
Muhlenbergia richardsonis, known by the common name mat muhly, is a species of grass. It is native to North America, where it can be found throughout much of Canada, Alaska, the western half of the contiguous United States through California, and in Baja California, Mexico.
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.
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.
Poa douglasii is a species of grass known by the common names Douglas' bluegrass and sand dune bluegrass. It is endemic to the coastline of California, where it grows in shifting sand dunes. It can be found mostly along the Central Coast and Channel Islands, and occasionally on the North Coast north of Mendocino. It is a perennial grass growing small, dense clumps up to about 30 centimeters in maximum height. It grows from a network of long rhizomes and stolons that anchor the grass to its loose sandy substrate; this network may be up to one meter long. The inflorescence is a dense, oval-shaped series of overlapping spikelets. The grass is dioecious, with male and female individuals producing different types of flowers in their inflorescences. This species, like many sand-dune endemic plants, is threatened by invasive species.
Polypogon australis is a species of grass known by the common names Chilean beard grass and Chilean rabbitsfoot grass. It is native to Chile and Argentina. It is also known in parts of the western United States where it is an introduced species and invasive species that grows in moist habitat types such as ditches.
Schismus barbatus is a species of grass known as common Mediterranean grass and kelch-grass. It is native to Eurasia, and it is also known as an introduced species in the southwestern United States. It grows in many habitats, including disturbed areas. It is an annual grass growing in small clumps. The stems grow up to 27 centimeters long and are lined with threadlike leaves. The short inflorescence bears spikelets under a centimeter long.
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.
Setaria viridis is a species of grass known by many common names, including green foxtail, green bristlegrass, and wild foxtail millet. It is sometimes considered a subspecies of Setaria italica. It is native to Eurasia, but it is known on most continents as an introduced species and is closely related to Setaria faberi, a noxious weed. It is a hardy grass which grows in many types of urban, cultivated, and disturbed habitat, including vacant lots, sidewalks, railroads, lawns, and at the margins of fields. It is the wild antecedent of the crop foxtail millet.
Spartina densiflora is a species of grass known by the common name denseflower cordgrass. It has been reclassified as Sporobolus montevidensis after a taxonomic revision in 2014, but Spartina densiflora is still in common usage. It is native to the coastline of southern South America, where it is a resident of salt marshes. It is also known on the west coast of the North America and parts of the Mediterranean coast as an introduced species and in some areas a noxious weed. In California it is a troublesome invasive species of marshes in San Francisco Bay and in Humboldt Bay, where it was introduced during the 19th century from Chile in ballast.
