The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, cranberry, sapote, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants and carnivorous plants.
Anagallis arvensis, commonly known as the scarlet pimpernel, red pimpernel, red chickweed, poor man's barometer, poor man's weather-glass, shepherd's weather glass or shepherd's clock, is a species of low-growing annual plant with brightly coloured flowers, most often scarlet but also bright blue and sometimes pink. The native range of the species is Europe and Western Asia and North Africa. The species has been distributed widely by humans, either deliberately as an ornamental flower or accidentally. A. arvensis is now naturalised almost worldwide, with a range that encompasses the Americas, Central and East Asia, the Indian Subcontinent, Malesia, the Pacific Islands, Australasia and Southern Africa.
The Primulaceae, commonly known as the primrose family, are a family of herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are perennial though some species, such as scarlet pimpernel, are annuals.
Artemisia vulgaris, the common mugwort, is a species of flowering plant in the daisy family Asteraceae. It is one of several species in the genus Artemisia commonly known as mugwort, although Artemisia vulgaris is the species most often called mugwort. It is also occasionally known as riverside wormwood, felon herb, chrysanthemum weed, wild wormwood, old Uncle Henry, sailor's tobacco, naughty man, old man, or St. John's plant. Mugworts have been used medicinally and as culinary herbs.
Lysimachia is a genus consisting of 182 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 nemorum, the yellow pimpernel, is a perennial flowering plant in the family Primulaceae.
Anagallis is a genus of about 20–25 species of flowering plants in the family Primulaceae, commonly called pimpernel. The scarlet pimpernel referred to in literature is part of this genus. The botanical name is from the Greek ana and agállein, and it refers to the opening and closing of the flowers in response to environmental conditions.
Myrsinoideae is a subfamily of the family Primulaceae in the order Ericales. It was formerly recognized as the family Myrsinaceae, or the myrsine family, consisting of 35 genera and about 1000 species. It is widespread in temperate to tropical climates extending north to Europe, Siberia, Japan, Mexico, and Florida, and south to New Zealand, South America, and South Africa.
Lysimachia monelli, the blue pimpernel or garden pimpernel is a species of flowering plant in the family Primulaceae, native to the Mediterranean region. It is not to be confused with Lysimachia foemina, which has very similar blue flowers, but broader leaves and can be found also in colder climates. In a comparison of DNA sequences, L. monelli was shown to be most closely related to L. foemina. The latter had been thought by many to be closest to L. arvensis, and some authors had even included L. foemina as a subspecies of L. arvensis. The three species were among several transferred from Anagallis to Lysimachia in a 2009 paper.
Theophrastoideae is a small subfamily of flowering plants in the family Primulaceae. It was formerly recognized as a separate family Theophrastaceae. As previously circumscribed, the family consisted of eight genera and 95 species of trees or shrubs, native to tropical regions of the Americas.
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 ciliata, the fringed loosestrife, is a species of flowering plant in the family Primulaceae. It is an erect herbaceous perennial growing to 120 cm (47 in) tall and 60 cm (24 in) broad, with opposite, simple leaves, and smooth green stems. The star-shaped yellow flowers are borne in midsummer. It is native to North America, including most of southern Canada and most of the United States except for the southwest. This plant is notable in that it is one of the few species of Lysimachia to bear elaiophores, that is, to offer oil instead of nectar as a reward to pollinators. It is pollinated in the northern part of its range by the specialist oil bee Macropis nuda, a native bee species whose survival depends upon this host plant.
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 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 lydgatei is a rare species of flowering plant in the family Primulaceae known by the common name Maui yellow loosestrife. It is endemic to Hawaii, where there are only four occurrences remaining on the island of Maui, the total number of plants under 300. It is federally listed as an endangered species of the United States.
Lysimachia foemina is commonly known as blue pimpernel or poor man's weatherglass, and was formerly called Anagallis foemina. It is a low-growing annual herbaceous plant in the genus Lysimachia of the family Primulaceae. In a comparison of DNA sequences, L. foemina was shown to be most closely related to L. monelli. It had been thought by many to be closest to L. arvensis, and some authors had even included L. foemina as a subspecies of L. arvensis, as Anagallis arvensis subsp foemina. These three species were among several transferred from Anagallis to Lysimachia in a 2009 paper.
Lysimachia clethroides, the gooseneck loosestrife, is a species of flowering plant, traditionally classified in the family Primulaceae. It was transferred to the family Myrsinaceae based on a molecular phylogenetic study, but this family was later merged into the Primulaceae.
Macropis nuda is a ground nesting, univoltine bee native to northern parts of North America. Thus, this species cocoons as pupae and hibernates over the winter. The species is unusual as it is an oligolectic bee, foraging exclusively for floral oils and pollen from Primulaceae of the species Lysimachia ciliata.
