Anemone multifida Poir.

G.Boraiah and M.Heimburger (1964) conducted an extensive cytotaxonomic analysis of this wide-ranging and extremely variable species and its relatives. The present treatment takes a broader view of the species (and its variation) and recognizes fewer entities. In addition, Anemone tetonensis and A . stylosa , plants treated as closely related species by G.Boraiah and M.Heimburger, are treated here as varieties of A . multifida .

Early-season plants of Anemone multifida var. multifida have solitary flowers and will key to var. saxicola . Anemone multifida var. tetonensis and especially var. saxicola might be based on characteristics that are influenced primarily by environment; further study is warranted.

Native Americans used Anemone multifida (no varieties specified) medicinally as an antirheumatic, cold remedy, nosebleed cure, and general panacea, as well as a means of killing lice and fleas (D. E. Moerman 1986).

Anemone multifida

provided by wikipedia EN

Anemone multifida is a species of flowering plant in the buttercup family known by the common names cutleaf anemone,[1] Pacific anemone and globe anemone. It is a perennial herb native to northern North America from Alaska to New York and as far south as Arizona and New Mexico. It is also known from parts of South America.

Description

This is a perennial herb which is quite variable in appearance, especially across varieties. It grows from a branching caudex to heights from 10 to 70 centimeters. The long petioled leaves are covered in a coat of long silky or coarse white hairs. Each leaf is divided into many long, pointed lobes, and the lobes are sometimes subdivided. Including the petiole a single leaf may be 5 to 20 centimeters long. The basal leaves are divided two or three times into narrow segments. The inflorescence holds one or more flowers. The flowers have no petals but four to eight (usually five) petallike sepals which may be nearly any color but typically white. They are somewhat hairy, especially on the outer surface. The center of the flower contains up to 80 stamens. The fruit is an achene that is woolly with long hairs, beaked, and a few millimeters long.[2]

Varieties

There are several varieties of this species:

  • A. m. var. multifida - throughout species range
  • A. m. var. saxicola (red windflower) - limited to western parts of species range
  • A. m. var. stylosa - limited to Utah and Arizona
  • A. m. var. tetonensis - limited to the montane west of the contiguous United States

Distribution and habitat

Anemone multifida is found growing on calcareous ledges, in areas with rocky or gravelly soils around lakes and other water ways, and on dunes.[2] In Minnesota it is record as growing in a prairie.[2]

It is typically found growing in subarctic and boreal areas in western and central North America but some populations are also found in mountainous and temperate habitats in the southern parts of its North American range. It is also found around the Great lakes region and there are rare occurrences in the north eastern US states and eastern Canada.[2]

A. multifada is poisonous as it has high ranunculin content: about 8.1% in aerial parts and 4% in root per dry weight.[3]
