Description
editEged's silverweed is a low-growing herbaceous plant with creeping red stolons up to 80 centimetres (31 in) long. The leaves are 10–40 cm (4–15+1⁄2 in) long, evenly pinnate into in crenate leaflets 3–5 cm (1+1⁄4–2 in) long and 2 cm broad, thinly covered with a few silky white trichomes (called hairs). The sparsity of the hairs is a useful distinction from A. anserina, which is more densely hairy.[citation needed]
The flowers are produced singly on 5–15 cm long stems, 2–3.5 cm diameter with five yellow petals. The fruit is a cluster of dry achenes.
Taxonomy
editIt was formerly classified in the genus Potentilla as Potentilla egedei. It is considered a member of the Argentina anserina species aggregate, or is alternatively treated as a subspecies of A. anserina by some botanists.[citation needed]
Distribution and habitat
editIt is a halophyte native to Arctic and cool temperate coasts of the Northern Hemisphere, most commonly growing in salt marshes. The southern limits of the range are California and Long Island, New York in North America, and the Baltic Sea and coastal eastern Siberia in Eurasia.[citation needed]
