Tridens muticus is a species of grass known by the common name slim tridens. [1] It is native to Mexico and the southwestern quadrant of the United States.
It grows several types of habitat, including plateau and desert, woodlands, sagebrush, plains, and other areas with dry sandy and clay soils.
It is a perennial grass forming a thick tuft with a knotted base and rhizome. It reaches a maximum height of 50 to 80 centimeters. The panicle has short branches appressed to the others, making the inflorescence narrow. The florets are generally purple in color.
This plant uses C4 carbon fixation as its method of energy metabolism. [2]
Cynodon is a genus of plants in the grass family. It is native to warm temperate to tropical regions of the Old World, as well as being cultivated and naturalized in the New World and on many oceanic islands.
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.
Tridens flavus, the purpletop tridens, red top, or greasegrass, is a large, robust perennial bunchgrass native to eastern North America.
Poa palustris is a species of grass native to Asia, Europe and Northern America. This plant is used as fodder and forage, and it also used for erosion control or revegetation.
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.
Chloris virgata is a species of grass known by the common names feather fingergrassfeathery Rhodes-grass and feather windmillgrass.
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.
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.
Enteropogon is a genus of tropical and subtropical plants in the grass family. It is widespread across many parts of Asia, Africa, Australia, the Americas, and various islands.

Piptatherum miliaceum is a species of grass known by the common name smilograss. It is native to Eurasia but it can be found in many other parts of the world as an introduced species and a casual weed of disturbed areas. It is a clumping perennial grass producing sturdy, erect stems that can reach 1.5 meters tall. The inflorescence is a panicle of several whorls of branches that divide into secondary branches bearing clusters of spikelets.
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.
Puccinellia nutkaensis is a species of grass known by the common names Nootka alkaligrass and Alaska alkali grass. It is native to North America from Alaska across northern Canada to Greenland and Nova Scotia, and down to Washington to Oregon to the Central Coast of California.
Puccinellia simplex is a species of grass known by the common names California alkaligrass and western alkali grass. It is native to California, where it grows in mineral springs and other moist habitat with saline soils in the Central Valley, Mojave Desert, and other areas. It is also known from Utah, but occurrences there are probably introduced. This annual grass grows up to about 25 centimeters tall. The inflorescence is generally a linear structure with parallel branches bearing small spikelets.

It is native to Europe, but it is known throughout the world as a common weed. It grows in lawns, sidewalks, roadsides, cultivated fields, and many other places. This annual grass grows 20 centimeters to well over a meter in height, its mostly hairless stems ranging from green to purple-tinged in color. The leaf blades are hairless on the upper surfaces, twisting, and up to 30 centimeters long. The inflorescence is a stiff, cylindrical bundle of spikelets 2 to 15 centimeters long with short, blunt bristles. The panicle may appear yellow or yellow-tinged.
Sporobolus airoides is a species of grass known by the common name alkali sacaton. It is native to western North America, including the Western United States west of the Mississippi River, British Columbia and Alberta in Canada, and northern and central Mexico.
