Sporobolus hookerianus is a species of grass known by the common name alkali cordgrass. [1]
It is native to western North America from north-western Canada through the western United States and eastern California, and into central Mexico. It grows in moist alkaline habitat, such as evaporating streams and shorelines, alkali flats, and inland marshes.
It is a perennial grass growing from short rhizomes. It produces usually single, slender stems reaching a meter in maximum height. The leaves are flat and ridged, and may roll in when new. The inflorescence is a narrow, dense, spike-like stick of branches appressed together, the unit reaching up to 25 centimeters long. The branches are lined with spikelets.
Halogeton glomeratus is a species of flowering plant in the family Amaranthaceae known by the common names saltlover, Aral barilla, and halogeton. It is native to Russia, Central Asia and China, but the plant is probably better known in the western United States, where it is an introduced species and a notorious noxious weed. This annual herb is a hardy halophyte, thriving in soils far too saline to support many other plants. It also grows in alkali soils such as those on alkali flats and disturbed, barren habitat. It can be found in sagebrush and shadscale habitat, and it grows well in areas with cold winters.
Danthonia californica is a species of grass known by the common name California oatgrass. This plant is native to two separate regions of the Americas, western North America from California to Saskatchewan, and Chile.
Bromus madritensis is a species of brome grass known by the common name compact brome. The specific epithet madritensis refers to Madrid, Spain. It has a diploid number of 28.
Krascheninnikovia lanata is a species of flowering plant in the family Amaranthaceae, known by the common name winterfat. It is native to much of western North America: from central Western Canada; through the Western United States; to northern Mexico.
Agrostis oregonensis is a species of grass known by the common name Oregon bent grass. It is native to western North America from Alaska to California to Wyoming, where it grows in several habitat types.
Deschampsia elongata is a species of grass known by the common name slender hairgrass.
Muhlenbergia asperifolia is a species of grass known as alkali muhly and scratchgrass. It is native to much of North America, including most of southern Canada, most of the continental United States except for the southeastern region, and parts of northern Mexico. It also grows in South America.
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 leptocoma is a species of grass known by the common names marsh bluegrass and western bog bluegrass.
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 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 parishii is an uncommon species of grass known by the common names bog alkaligrass and Parish's alkali grass. It is native to the western United States, where it is known from a few locations in Arizona and New Mexico, and one occurrence each in California and Colorado.
Puccinellia pumila is a species of grass known by the common names dwarf akaligrass and smooth alkali grass. It is native to North America where it grows along the coastline in the northern latitudes, from Alaska across Arctic northern Canada to Greenland. It occurs on the coast of the Pacific Northwest in the United States and it is known from the Kamchatka Peninsula. The grass is only found on the coast, in wetland habitat, beaches, and areas inundated by the highest tides, in saline sand and mud. This perennial grass grows decumbent or erect to a maximum height near 40 centimeters, often remaining much smaller, especially in harsh habitat. It may root at stem nodes which become buried in wet substrate. The inflorescence is a dense or open array of branches bearing spikelets.
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.
Pyrrocoma lucida is a species of flowering plant in the family Asteraceae known by the common names sticky goldenweed and sticky pyrrocoma. It is endemic to California, where it is known only from the northern Sierra Nevada. It grows in mountain forests and clay flats with alkali soils. This is a perennial herb growing from a taproot, producing an erect stem up to 75 centimetres (30 in) tall. It is hairless and glandular, its surface resinous and shiny. The leaves are lance-shaped with sharply toothed edges, the largest near the base of the stem reaching 25 centimetres (10 in) in length. Smaller leaves up to 10 centimetres (4 in) long occur higher on the stem. The inflorescence is a narrow spikelike array of many flower heads lined with thick, overlapping, gland-dotted phyllaries. Each head contains up to 40 yellow disc florets surrounded by a fringe of up to 20 yellow ray florets. The fruit is an achene up to a centimeter long including its pappus.
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.
Sidalcea covillei is an uncommon species of flowering plant in the mallow family known by the common names Owens Valley sidalcea, and Owens Valley checkerbloom. It is endemic to the Owens Valley of Inyo County, California, where it grows on alkali flats and in alkaline meadows and springs. While it is limited to this single valley, it is known from 44 sites there, and several populations are relatively large, with the total global population estimated at about two million individuals.
Spergularia macrotheca is a species of flowering plant in the family Caryophyllaceae known by the common name sticky sandspurry. It is native to western North America from British Columbia to Baja California, where it grows in many types of moist coastal and inland habitat, often in alkaline and saline substrates. It may be found in marshes, alkali flats, beaches, meadows, seeps, and vernal pools. It is a perennial herb producing a narrow stem up to 40 centimeters long with a woody, thickened base and taproot. They may grow erect or prostrate across the ground. It is covered in sticky glandular hairs, especially in the inflorescence. The stems are lined with fleshy linear leaves, sometimes tipped with spines. The leaves are accompanied by triangular stipules up to a centimeter long each. Flowers occur in clusters at the end of the stem as well as in leaf axils. The small flowers have five pointed sepals and five oval white to lavender-pink petals. The fruit is a capsule containing tiny reddish brown, winged seeds.
