Lythrum alatum

Lythrum alatum, commonly known as winged loosestrife, winged lythrum or (in Britain and Ireland) angled purple-loosestrife, [1] is a species of flowering plant belonging to the family Lythraceae. It is endemic to wetland areas in central and eastern United States and Ontario. [2]

Description

Winged loosestrife is an upright, branching herbaceous plant growing to about one metre tall. The stems are woody in the lower parts of the plant, square in cross section with slightly winged angles. The leaves are mostly opposite, stalk-less, broadly oblong and tapering towards the tip. They have smooth un-toothed edges. The flowers are borne singly or in pairs in the axils of the much reduced upper leaves. The calyx forms a tube about 0.6 millimetres long and has six pointed teeth. The six rose-pink petals have a magenta central vein and are about 5 millimetres long and 2 millimetres wide. There are six stamens with pink filaments and purple anthers. The stigma is white and the style green. [3] The ovary is superior and the fruit is an elongated capsule with numerous tiny seeds. [4]

Habitat

Winged loosestrife is found growing in wet meadows and fens, pond and lake margins, beside streams and by railroads. [3]

Conservation status in the United States

It is listed as endangered in Connecticut, [5] Maryland, and Pennsylvania. [6] It was thought to be extinct in Vermont until it was found in the town of Monkton in 2017. [7]

As a noxious weed in the United States

The Lythrum genus is listed as a noxious weed in Michigan, North Carolina, and Wisconsin. [8]

Native American ethnobotany

The Cherokee take an infusion for Lythrum alatum var. lanceolatum for the kidneys. [9]

It is native to Europe, and it is found in parts of western North America as an introduced species. It often grows in moist habitat, such as marshes. This is a prostrate annual herb producing a hairless, reddish stem up to 25 centimeters long which lies along the ground and roots where its nodes come in contact with wet earth. The slightly fleshy, spoon-shaped leaves are about a centimeter long and greenish to reddish in color. Solitary flowers occur in leaf axils. Flowers often have white or pink petals about a millimeter long, but some lack petals. The fruit is a spherical capsule containing minute seeds.

Veronica anagallis-aquatica is a species of flowering plant in the family Plantaginaceae known by the common names water speedwell, blue water-speedwell,brook pimpernel, and sessile water-speedwell. It is also listed as Veronica catenata. Its true native range is not clear, but the plant is present on most continents, and in most places it is probably naturalized. It occurs in many types of moist and wet habitat, and it is semi-aquatic, often growing in shallow water along streambanks, in ponds, and in other wetland environments. It is a rhizomatous perennial herb with stems growing 10 centimeters to about a meter in maximum length. It may be decumbent, the stem spreading along the ground and rooting where it touches moist substrate, or erect in form. The oppositely arranged leaves are green, smooth-edged or toothed, and sometimes clasping the stem where the leaf pairs meet at the bases. The inflorescence is a raceme of many flowers arising from the leaf axils. Each flower is borne on a short, curving pedicel. The flower corolla is up to a centimeter wide with four lobes, the upper lobe being widest. It is blue, lavender, or violet with purple lines near the base of each lobe. At the center are two small protruding stamens.
