2011).
Habitat: Wetlands.
Description: It is a slender, annual
herb 90–150 cm tall. Stems are redtinged, slender, and leaves are broadly
triangular and acute up to 7 cm long.
This species has five-petaled white to
pink flowers arranged in a compound

and culinary purposes in Europe and
Asia (Healthwithfood.org; Ratan and
Kothiyal, 2011).
