Lythrum salicaria or purple loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia.
Lysimachia is a genus consisting of 193 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae.
Lythrum is a genus of 38 species of flowering plants native to the temperate world. Commonly known as loosestrife, they are among 32 genera of the family Lythraceae.
Saxifraga cernua, the drooping saxifrage, nodding saxifrage or bulblet saxifrage, is a flower common all over the High Arctic. It stretches further south in mountainous areas of the Alps, Norway, Iceland, Siberia and Alaska.
Lysimachia europaea is a flowering plant in the primrose family Primulaceae, called by the common name chickweed-wintergreen or arctic starflower. It is a small herbaceous perennial plant with one or more whorls of leaves on a single slender erect stem. It is about one third of a foot high (10 cm). The broad lanceolate leaves are pale green but take on a copper hue in late summer. The solitary white flowers are reminiscent of small wood anemones and appear in midsummer. The fruits are globular dry capsules but are seldom produced.
Lobelia siphilitica, the great blue lobelia, great lobelia, or blue cardinal flower, is a plant species within the family Campanulaceae. It is an herbaceous perennial dicot native to eastern and central Canada and United States. There are two recognized varieties of Lobelia siphilitica, var. siphilitica and var. ludoviciana. Blooming from August to October, it is short-lived, lasting only for a few years.
Hydrocotyle vulgaris, the marsh pennywort, common pennywort, water naval, money plant, lucky plant or copper coin, is a small creeping aquatic perennial plant native to North Africa, Europe, the Caucasus and parts of the Levant.
Lysimachia thyrsiflora, the tufted loosestrife, is a plant in the genus Lysimachia. It is native to large sections of the northern Northern Hemisphere, including Eurasia and North America. It often grows in marshes, shorelines of lakes and ponds and occasionally along streams. It is an erect perennial herb growing up to 80 centimeters tall and bearing yellow flowers, sometimes dotted with purple. It may be confused with purple loosestrife when not blooming but can be easily distinguished because purple loosestrife has a square stem. Tufted loosestrife has been used medicinally in Asia to combat high blood pressure.
Lysimachia vulgaris, the yellow loosestrife or garden loosestrife, is a species of herbaceous perennial flowering plant in the family Primulaceae. It was transferred to Myrsinoideae based on results of molecular phylogenetic research before being merged into the Primulaceae.
Lysimachia quadrifolia, the whorled loosestrife, whorled yellow loosestrife, or crosswort, is a species of herbaceous plant in the family Primulaceae. It native to the eastern United States and Canada.
Lysimachia fraseri is a rare species of flowering plant in the primrose family known by the common name Fraser's yellow loosestrife. It is native to the Southeastern United States, where it is listed as an endangered species in several states.
Lythrum portula is a species of flowering plant in the loosestrife family known by the common names water-purslane and spatulaleaf loosestrife. 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.
Lysimachia punctata, the dotted loosestrife, large yellow loosestrife, circle flower, or spotted loosestrife, is a flowering plant species in the family Primulaceae.
Lysimachia asperulifolia is a rare species of flowering plant in the Primulaceae known by the common name rough-leaved loosestrife and roughleaf yellow loosestrife. It is endemic to the Atlantic coastal plain in North Carolina and northern South Carolina in the United States, where there are 64 known populations. It is a federally listed endangered species of the United States.
Lysimachia hybrida, common name Mississippi loosestrife or lowland yellow loosestrife, is a plant species widespread in much of the United States and Canada, absent only from the deserts in the west and the Arctic and sub-Arctic regions of the far north. It prefers moist locales such as marshes, swamps, wet meadows, stream banks, etc.
Lysimachia quadriflora, the fourflower yellow loosestrife, is a species of herbaceous plant in the family Primulaceae. It native to the eastern United States and Canada.
Monostegia is a genus of sawfly. The authority is based on the description by Achille Costa and Oronzio Costa, although earlier work grants this to Fabricius 1798., though the most common species, M. abdominalis, bears the authority of Fabricius.
Platanthera dilatata, known as tall white bog orchid, bog candle, or boreal bog orchid is a species of orchid, a flowering plant in the family Orchidaceae, native to North America. It was first formally described in 1813 by Frederick Traugott Pursh as Orchis dilatata.
Lysimachia × commixta is a hybrid of flowering plants in the primrose family Primulaceae. It is native to eastern North America, from eastern Canada across the Great Lakes region west to Minnesota. The hybrid specific epithet commixta means "mixed together, mixed up", which presumably refers to the genetic mixing of two species. Indeed, the hybrid is sometimes referred to as the mixed loosestrife or the commingling loosestrife.
Lysimachia × producta is a hybrid of flowering plants in the primrose family Primulaceae. It is native to eastern North America, from Quebec south to North Carolina, as far west as Wisconsin. The hybrid specific epithet producta means "stretched out, extended", a reference to the shape of its inflorescence. Indeed, the hybrid is sometimes referred to as the elongated loosestrife.
