Lysimachia quadriflora, the fourflower yellow loosestrife, [1] is a species of herbaceous plant in the family Primulaceae. It native to the eastern United States and Canada.
Lysimachia quadriflora is an erect branched forb growing to a maximum height of about 2 feet (0.61 m). It grows in moist to wet conditions in calcareous soils. The leaves are linear, firm, with mostly smooth edges. The flowers grow from an inflorescence cluster at the ends of the stems and branches. The five-parted flower is yellow with a reddish center and blooms from July to August. [2] Its habitats include wet meadows, prairies, fields, swamps, and marshes. [3]
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.
Lysimachia nummularia is a species of flowering plant in the primrose family Primulaceae. Its common names include moneywort, creeping jenny, herb twopence and twopenny grass.
Grindelia squarrosa, also known as a curly-top gumweed or curlycup gumweed, is a small North American biennial or short-lived perennial plant.
Helenium autumnale is a North American species of poisonous flowering plants in the family Asteraceae. Common names include common sneezeweed and large-flowered sneezeweed.
Rosa carolina, commonly known as the Carolina rose, pasture rose, or prairie rose, is a perennial shrub in the rose family native to eastern North America. It can be found in nearly all US states and Canadian provinces east of the Great Plains. It is common throughout its range and can be found in a wide variety of open habitats, from thickets and open woods to roadsides and along railroads.
Downingia yina is a distinctive, colorful wildflower known by the common name Cascade calico-flower. It bears small, easily recognizable flowers up to 1 centimeter in width. Each flower has three fused lower petals which are blue or violet with a central spot which is white with a yellow center. This pattern is attractive to pollinating insects and helps them navigate to the flower's center. The two upper blue petals may fold together to face each other, or stick straight out.
Hypericum anagalloides is a species of flowering plant in the St. John's wort family Hypericaceae. It is known by the common names creeping St. John's-wort, tinker's penny and bog St. John's-wort.
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.
Caltha leptosepala, the white marsh marigold, twinflowered marsh marigold, or broadleaved marsh marigold, is a perennial species of flowering plant in the buttercup family. It is native to western North America from Alaska to New Mexico, where it grows in wet mountain habitats in alpine and subalpine regions. There are two general wild types of this species, one native to the interior and one that grows along the Pacific coast and coastal mountains, but these are not always treated separately.
Viburnum lantanoides is a perennial shrub of the family Adoxaceae, growing 2–4 meters (6–12 ft) high with pendulous branches that take root where they touch the ground. These rooted branches form obstacles which easily trip walkers – hence the common name.
Lysimachia terrestris is a plant in the family 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 punctata, the dotted loosestrife, large yellow loosestrife, circle flower, or spotted loosestrife, is a flowering plant species in the family Primulaceae.
Lysimachia filifolia is a rare species of flowering plant in the Primulaceae known by the common name Wailua River yellow loosestrife. It is endemic to Hawaii, where there are two populations on Oahu and one on Kauai. It is a federally listed endangered species of the United States.
Lysimachia iniki is a rare species of flowering plant in the family Primulaceae known by the common names Wailua River yellow loosestrife and Wailua River island-loosestrife. It is endemic to Hawaii, where there is only one known occurrence existing on the island of Kauai. The plant was federally listed as an endangered species of the United States in 2010.
Lysimachia maxima is a rare species of flowering plant in the family Primulaceae known by the common name Pelekunu Trail yellow loosestrife. It is endemic to Hawaii, where there are only two small populations remaining on the island of Molokai. It is federally listed as an endangered species of the United States.
Lysimachia pendens is a rare species of flowering plant in the family Primulaceae known by the common name broad-leaf yellow loosestrife. It is endemic to Hawaii, where there is a single occurrence known on the island of Kauai. It was federally listed as an endangered species of the United States in 2010.
Hypericum punctatum, the spotted St. John's wort, is a perennial herb native to North America. The yellow-flowered herb occurs throughout eastern North America into southern Canada. The process of microsporogenesis carried out by this plant is prone to errors in chromosomal segregation. It has a diploid number of 14 or 16. Insects are attracted to the plant's pollen and the hypericin in the plant's leaves is toxic to mammals.
Hypericum densiflorum, also known as bushy St. John's wort or dense St. John's wort, is a perennial herb in the flowering plant family Hypericaceae native to North America. The specific epithet densiflorum is Latin, meaning "densely flowered", referring to the many-flowered cymes.
