Шаблон:Short description Шаблон:Speciesbox
Arnica cordifolia is a species of arnica in the sunflower family, known by the common name heartleaf arnica.[1] It is native to western North America.
Description
This is a rhizomatous perennial herb producing one or more erect stems reaching a maximum height of about Шаблон:Convert.[2] It has two to four pairs of leaves on the stem, each on a long petiole. The leaves are heart-shaped to arrowhead-shaped and finely toothed along the edges. The inflorescence bears one or more daisylike flower heads Шаблон:Convert in width,[2] lined with white-haired phyllaries and sometimes studded with resin glands. The center of each head contains golden yellow disc florets and a fringe of 10–15 bright golden ray florets approaching Шаблон:Convert in maximum length.[2][3][4][5][6] The flowers usually bloom from April to June, but sometimes do so as late as September.[2]
The fruit is a hairy achene up to Шаблон:Convert long, not counting its off-white pappus. Seeds are dispersed on the wind. An individual plant can live 12 years, surviving periodic wildfire by resprouting from its long, slender rhizome afterward.[6][7]
The species could be confused with the similar Arnica latifolia, from which it can be distinguished by the leaves. The leaves of A.Шаблон:Nbspcordifolia are larger and heart-shaped.[8]
Distribution and habitat
It is native to western North America from Alaska to California to New Mexico, as far east as Ontario and Michigan.[9][10] It is a plant of many habitat types, including coniferous forests, and moist mountain meadows from sea level to altitudes of above Шаблон:Convert, but most commonly between Шаблон:Convert.[9][6]
Uses
The dried leaves can be made into a poultice or tincture to treat strains and bruises.[11]
