Bitterroot is a small perennial herb in the family Montiaceae. Its specific epithet rediviva refers to its ability to regenerate from dry and seemingly dead roots.
Astragalus is a large genus of over 3,000 species of herbs and small shrubs, belonging to the legume family Fabaceae and the subfamily Faboideae. It is the largest genus of plants in terms of described species. The genus is native to temperate regions of the Northern Hemisphere. Common names include milkvetch, locoweed and goat's-thorn. Some pale-flowered vetches are similar in appearance, but they are more vine-like than Astragalus.
Bitterroot National Forest comprises 1.587 million acres (6,423 km²) in west-central Montana and eastern Idaho, of the United States. It is located primarily in Ravalli County, Montana, but also has acreage in Idaho County, Idaho (29.24%), and Missoula County, Montana (0.49%).
Astragalus newberryi, is a flowering plant in the family Fabaceae, native to the western United States from Idaho to New Mexico and California. A variety is found in the Death Valley area and the eastern Mojave Desert in California and Nevada. It grows in rocky and gravelly areas between 1,300–2,350 metres (4,270–7,710 ft) elevation.
Astragalus agrestis is a species of milkvetch known by the common names purple milkvetch, purple loco, and field milkvetch. It is native to much of western and northern North America from most of Canada to the southwestern United States, as well as eastern Asia. It grows in vernally moist areas such as meadows, and is often found in sagebrush.
Astragalus brauntonii is a rare species of milkvetch known by the common name Braunton's milkvetch. It is endemic to California, where it is known from fewer than 20 extant occurrences in the hills and mountains surrounding the Los Angeles Basin in Southern California. This is a federally listed endangered species in the United States.
Astragalus purshii is a species of milkvetch known by the common names woollypod milkvetch and Pursh's milkvetch.
Astragalus pycnostachyus is a species of milkvetch known by the common name marsh milkvetch. It is endemic to the coastline of California, where it grows in wet saline habitat such as marshes.
Astragalus desereticus is a rare species of milkvetch known by the common name Deseret milkvetch. It is endemic to Utah County, Utah, where it is known from only one population. It was thought to be extinct until 1981 when this population was discovered. The population contains 5,000 to 10,000 plants on an area of land covering less than 300 acres. It is vulnerable to damage from grazing cattle, which eat the plant and trample the soil, and from development and erosion. This is a federally listed threatened species.
Astragalus cicer, the chickpea milkvetch, chick-pea milk-vetch or cicer milkvetch, is a perennial flowering plant native to Eastern Europe, popularized and subsequently transported to areas in Southern Europe, North America, and South America. Cicer milkvetch exhibits legume-like qualities; the plant produces pods which harbor its seeds. Its flowers are usually of pale yellow tint, and as such, attract bumble or European honey bees for pollination. Growth often exceeds 0.6 meters, up to a height of 1 meter in length.
Astragalus montii is a rare species of flowering plant in the legume family known by the common name heliotrope milkvetch. It is endemic to Utah in the United States, where there are only three known populations. It is a federally listed threatened species of the United States. This species is often treated as a variety of Astragalus limnocharis.
Lewisia maguirei is a rare species of flowering plant in the family Montiaceae known by the common name Maguire's lewisia, or Maguire's bitterroot. It is endemic to Nevada in the United States, where it is known only from eastern Nye County.
Astragalus barrii is a species of flowering plant in the legume family known by the common name Barr's milkvetch. It is native to the United States, where it is a "regional endemic", occurring in parts of southwestern South Dakota, northeastern Wyoming, southeastern Montana, and Nebraska.
Astragalus leptaleus is a species of flowering plant in the legume family known by the common name park milkvetch. It is native to the Rocky Mountains of the United States, where it occurs in Idaho, Montana, Wyoming, and Colorado.
Astragalus molybdenus is a species of flowering plant in the legume family known by the common names Leadville milkvetch and molybdenum milkvetch. It is endemic to Colorado in the United States. If the separate species Astragalus shultziorum and Astragalus lackschewitzii are included in A. molybdenum the range expands into Wyoming and Montana.
Astragalus iodanthus is a species of flowering plant in the legume family, Fabaceae, known by the common names Humboldt River milkvetch and violet milkvetch. It is native to the western United States, where its range includes California, Idaho, Nevada, Oregon, and Utah. It grows on hills and in valleys in barren sandy and volcanic soils in habitat such as sagebrush.
Astragalus drummondii is a species of flowering plant in the legume family known by the common name Drummond's milkvetch. The botanist Thomas Drummond first identified the plant during his travels in North America from 1825 to 1835, the year of his death. Accordingly, A. drummondii, amongst many other plants, was named after the late botanist. Upon the return of samples collected by Drummond to England, his findings were published in Sir William Hooker’s Flora Boreali-Americana in 1840.
Astragalus cibarius, commonly called the browse milkvetch, is a species of plant in the legume family.
Astragalus aquilonius, the Lemhi milkvetch, is a species of milkvetch in the family Fabaceae. It is native to Idaho.
