Astragalus neglectus, or Cooper's milkvetch, is a species of flowering plant in the family Fabaceae native to northeastern North America.
Astragalus neglectus is a perennial, herbaceous plant growing 30 to 90 cm tall. [2] The alternate, compound leaves have 11-25 leaflets. [3] The 10 to 20 white or creamy flowers form a cluster arising from the upper leaf axils. [3] The fruit is in the form of an inflated pod. [3]
The first published description of the species (as Phaca neglecta) was in A Flora of North America by John Torrey and Asa Gray in 1838. [4] The species is called Cooper's milkvetch after a William Cooper who discovered the plant described by Gray in 1856 as Astragalus cooperi (which ultimately was considered to be the same entity as A. neglectus). [5]
The range of Astragalus negelctus is centred around the Great Lakes, [3] but it also occurs from Manitoba and South Dakota east to Massachusetts and Virginia. [6] It is rare throughout most of its range. [3] It is found in wet to dry, open, often rocky habitats, especially those that are calcareous. [7] Natural disturbance is required to maintain these open habitats. [2]
Although ranked globally as apparently secure (G4), this species is considered to be a rare and potentially vulnerable species within most of the states and provinces it occurs. [1] It is classified as endangered in Wisconsin. [8] It was formerly considered to be at risk in Minnesota, but it was delisted after the discovery of numerous new populations in the 1990s. [3]
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.
Erythronium propullans, the Minnesota dwarf trout lily, Minnesota adder's tongue or Minnesota fawnlily, is a rare plant endemic to the Cannon River and North Fork Zumbro River watersheds in Rice County, Goodhue County and the extreme northern edge of Steele County, Minnesota, in the United States. The plants are believed to be a mutation or sport of the white trout lily and evolved following the most recent ice age.
Astragalus bibullatus, the limestone glade milkvetch or Pyne's ground plum, is an endangered species of flowering plant that is endemic to the cedar glades of the central basin of Tennessee in the United States. It is found in only eight populations located within a few kilometers of each other in Rutherford County, Tennessee.
Astragalus lemmonii, the Lemmon's milkvetch, is a rare plant of eastern California. It is a member of the bean family, the Leguminosae, and specifically a member of the subfamily Papilionoideae. The genus Astragalus is a large genus within this family; members of this genus are known as milkvetches or locoweeds. Close relatives of this particular species include Astragalus peckii and Astragalus lentiformis.

Astragalus lentiginosus is a species of legume known by the common names spotted locoweed and freckled milkvetch. It is native to western North America, where it grows in many habitat types. There are a great number of wild varieties of this species, and they vary in appearance. The flower and the fruit of a given individual are generally needed to identify it down to the variety.
Astragalus clarianus is a rare species of milkvetch known by the common names Clara Hunt's milkvetch and Napa milkvetch. It is endemic to northern California where it is known from only four or five occurrences along the border between Sonoma and Napa Counties. It is a federally listed endangered species.

Trillium recurvatum, the prairie trillium, toadshade, or bloody butcher, is a species of perennial herbaceous flowering plant in the family Melanthiaceae. It is native to parts of central and eastern United States, where it is found from Iowa south to Texas and east to North Carolina and Pennsylvania. It grows in mesic forests and savannas, often in calcareous soils. It is also known as bloody noses, red trillium, prairie wake-robin, purple trillium, and reflexed trillium, in reference to its reflexed sepals.
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 osterhoutii is a rare species of milkvetch known by the common name Osterhout milkvetch. It is endemic to Grand County, Colorado, where it is known from a few populations in Middle Park, a mountain basin. There are five or six occurrences. It is a federally listed endangered species.
Cypripedium arietinum, the ram's head lady's slipper, is a rare orchid that grows in lightly shaded areas with calcareous soils. It is characteristic of the alvars around the Great Lakes in North America, as well as in New England. In Canada, it is found from Quebec to Saskatchewan, plus an isolated population in Nova Scotia, where it grows on gypsum based soils, 330 km away from the nearest population in Maine.
Solidago houghtonii is a rare North American species of flowering plant in the aster family known as Houghton's goldenrod. It is native to southern Ontario, Canada and the northern United States. It is threatened by the loss and degradation of its habitat. It is a federally listed threatened species of the United States and it is designated a species of special concern by Canada's Committee on the Status of Endangered Wildlife in Canada.
Carex lacustris, known as lake sedge, is a tufted grass-like perennial of the sedge family (Cyperaceae), native to southern Canada and the northern United States.

Charles Lewis Anderson was an American medical doctor who, in addition to the practice of medicine, made important contributions to fields of natural history, especially botany. Educated in Indiana, he spent most of his professional life in the upper Midwest and West. Many plants collected by him were subsequently named in his honor. He wrote about local natural history, and actively engaged in public service in places where he resided.
