Bidens aristosa is a North American species of plants in the sunflower family.
 Common names include bearded beggarticks, western tickseed, long-bracted beggarticks, tickseed beggarticks, swamp marigold, and Yankee lice.
 It is native to eastern and central United States and south-central Canada, from Maine south to Florida and west as far as Ontario, Texas, and Nebraska.
Bidens is a genus of flowering plants in the aster family, Asteraceae.
 The common names beggarticks, black jack, burr marigolds, cobbler's pegs, Spanish needles, stickseeds, tickseeds and tickseed sunflowers refer to the fruits of the plants, most of which are bristly and barbed, with two sharp pappi at the end.
 The generic name refers to the same character; "Bidens" comes from the Latin "bis" ("two") and "dens" ("tooth").
Primula is a genus of mainly herbaceous flowering plants in the family Primulaceae.
 They include the familiar wildflower of banks and verges, the primrose ("P. vulgaris").
 Other common species are "P. auricula" (auricula), "P. veris" (cowslip) and "P. elatior" (oxlip).
 These species and many others are valued for their ornamental flowers.
 They have been extensively cultivated and hybridised - in the case of the primrose, for many hundreds of years.
 "Primula" are native to the temperate northern hemisphere, south into tropical mountains in Ethiopia, Indonesia and New Guinea, and in temperate southern South America.
 Almost half of the known species are from the Himalayas.
Lachenalia is a genus of bulbs in the family Asparagaceae, subfamily Scilloideae, which are usually found in Namibia and South Africa.
 Most of these plants have a dormancy period, and the new roots of these plants will always grow every year.
 "Lachenalia" is named after the Swiss botanist Werner de Lachenal (1736-1800).
 Species are sometimes known as "Cape cowslip" though they are not directly related to the true cowslip "Primula veris".
Bidens tripartita is a common and widespread species of plants in the sunflower family, Asteraceae, commonly known as three-lobe beggarticks, three-part beggarticks, leafy-bracted beggarticks or trifid bur-marigold.
 It is native to much of Eurasia, North Africa, and North America, with naturalized populations in Australia and on some Pacific Islands.
Epiblema otiosana, the bidens borer, gets its common name from the genus "Bidens" which includes the food plants for the larva.
 An adults wingspan ranges from 12 to 20 mm.
 They range in North America from Maine and Ontario in the north, south to Florida and west to Kansas and Texas.
Cortusa is a genus that consists of 19 species of delicate, hardy, alpine perennials, relative to "Primula" both in general appearance and habit of growth.
 The genus is named by the herbalist Matthiolus after his friend Cortusus, professor of botany at Padua, who discovered the plant called today "Cortusa matthioli".
 The plants are flowering herbaceous perennials native to the mountains of southern and eastern Europe, including the Alps and the Carpathians, and some species native to China.
 Most of the species are small spring bloomers for shade and rock garden.
 These low-growing and rather handsome little plants have clumps of downy, light green, heart-shaped leaves with serrated edges.
 In late spring, small loose umbel of delicate bell-shaped to lily-liked flowers born terminally on drooping spikes arise from the base, some 6-8in high.
 Flowers are magenta, pink, white and yellow.
 They are dormant in some months, and as spring begins, stems and leaves quickly start to reproduce.
Oenothera is a genus of about 145 species of herbaceous flowering plants native to the Americas.
 It is the type genus of the family Onagraceae.
 Common names include evening primrose, suncups, and sundrops.
 They are not closely related to the true primroses (genus "Primula").
Bidens triplinervia is a Latin American species of flowering plants in the sunflower family.
 It is native to Mesoamerica and South America, from Chihuahua State in northern Mexico to Jujuy Province in northern Argentina.
Volemitol is a naturally occurring seven-carbon sugar alcohol.
 It is a substance widely distributed in plants, red algae, fungi, mosses, and lichens.
 It was also found in lipopolysaccharides from "E. coli".
 In certain higher plants, such as "Primula", volemitol plays several important physiological roles.
 It functions as a photosynthetic product, phloem translocate, and storage carbohydrate.
