Persicaria pensylvanica (L.) M. Gómez

Comments ( englanti )

tarjonnut eFloras
Persicaria pensylvanica is a morphologically variable allotetraploid, with P. lapathifolia probably one of the parents (L. L. Consaul et al. 1991). Three or four varieties (under Polygonum) often have been accepted in North American floras; the characters on which these are based vary greatly within and among populations. J. W. Taylor-Lehman (1987) concluded that Polygonum pensylvanicum is best treated as a polymorphic species without infraspecific taxa, based on specimens primarily from Ohio. The heterostylous Persicaria bicornis often is included in P. pensylvanica. A single chromosome count of 2n = 22 reported by Á. Löve and D. Löve (1982), which could not be confirmed by Consaul et al. because the voucher could not be found, is excluded. Flowers with three styles and trigonous achenes are produced; they are exceedingly rare and probably mostly overlooked. Several Native American tribes prepared infusions and decoctions from P. pensylvanica, which they used as drugs for humans and horses (D. E. Moerman 1998).

Persicaria pensylvanica ( englanti )

tarjonnut wikipedia EN

Persicaria pensylvanica (syn. Polygonum pensylvanicum[1]) is a species of flowering plant in the buckwheat family, Polygonaceae. It is native to parts of North America, where it is widespread in Canada and the United States.[2] It has also been noted as an introduced species in parts of Europe and South America.[3] Common names include Pennsylvania smartweed and pinkweed.[2]

Description

Pennsylvania smartweed is a variable annual herb reaching 10 cm (3.9 in) to 2 m (6.6 ft) tall. The upright, ribbed stems are branching or unbranched. The lance-shaped leaves reach up to about 2 cm (0.79 in) in length. The blade may be marked with a dark blotch. The brownish ochrea at the base is up to 2 cm (0.79 in). The inflorescences grow at the top of the stem and from the leaf axils. The flowers have five pinkish or greenish tepals each a few millimeters long.[3]

This plant grows in moist, disturbed habitat types, such as ponds, reservoirs, riverbanks, irrigated fields, and ditches.[3]

Ecology

This plant is an important part of the habitat for waterfowl and other birds, which use it for food and cover. At least 50 species of birds have been observed feeding on the seeds, including ducks, geese, rails, bobwhites, mourning dove, and ring-necked pheasant. The seeds and other parts are eaten by mammals such as the white-footed mouse, muskrat, raccoon, and fox squirrel.[4]

Traditional native American medicine

Native Americans have various uses for the plant. The Chippewa use it for epilepsy.[5][6] The Iroquois use it for horse colic.[5][7] The Menominee take a leaf infusion for hemorrhage of blood from the mouth and post-partum healing.[5][8] The Meskwaki use it on bleeding hemorrhoids.[5][9]
