Clintonia is a genus of flowering plants in the lily family Liliaceae. Plants of the genus are distributed across the temperate regions of North America and eastern Asia, in the mesic understory of deciduous or coniferous forests. The genus, first described by Constantine Samuel Rafinesque in 1818, was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York. For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead refer to the distinctive fruit of members of the genus. Since fruit color varies somewhat across species, the common name bead lily is used as well.
Claytonia perfoliata, also known as miner's lettuce, Indian lettuce, winter purslane, or palsingat (Cahuilla), is a flowering plant in the family Montiaceae. It is an edible, fleshy, herbaceous, annual plant native to the western mountain and coastal regions of North America, from southernmost Alaska and central British Columbia, all the way south to Central America, but most common in California in the Sacramento and northern San Joaquin Valleys. Recently as 2019 sightings of this plant have been found as far inland as Arkansas.

Claytonia sibirica, the pink purslane, candy flower, Siberian spring beauty or Siberian miner's lettuce, is a flowering plant in the family Montiaceae, native to the Commander Islands of Siberia, and western North America from the Aleutian Islands and coastal Alaska south through the Queen Charlotte Islands, Vancouver Island, Cascade and Coast Ranges, to a southern limit in the Santa Cruz Mountains. Populations are also known from the Wallowa Mountains, Klamath Mountains, northern Idaho, and The Kootenai. A synonym is Montia sibirica. The plant was introduced into the United Kingdom by the 18th century, where it has become very widespread.
Claytonia exigua is a species of wildflower known by the common names serpentine springbeauty and pale claytonia, in the family Montiaceae.
Claytonia megarhiza is a species of wildflower in the family Montiaceae known by the common names fell-fields claytonia and alpine springbeauty. It is native to western North America from northwestern Canada to New Mexico, where it grows in rock crevices and talus habitats in subalpine and alpine climates. The species is known from summits and slopes of North America's highest mountains including the Redstone Mountains of the Canadian Northwest Territories, disjunct south to the central and southern Rocky Mountains reaching a southern limit in the Sangre de Cristo Mountains. The specific epithet megarhiza is Greek for "large roots".
Claytonia palustris is a species of wildflower in the family Montiaceae known by the common names Jonesville springbeauty and marsh claytonia.
Claytonia parviflora is a species of wildflower in the family Montiaceae known by the common name Indian lettuce. It is native to western North America from southwestern Canada to northwestern Mexico, where it is found in many types of habitat, particularly areas that are moist in the spring.
Claytonia caroliniana, the Carolina springbeauty, is an herbaceous perennial in the family Montiaceae. It was formerly placed in the Portulacaceae. Its native range is eastern and central North America. It is most commonly found in the New England area of the United States but its habitat extends from Ontario and a northern limit in the Cape Anguille Mountains of Newfoundland and south to Alabama. It grows approximately 6 inches tall in forests of the Appalachian Mountains and piedmont
Claytonia tuberosa, commonly known as Beringian springbeauty or tuberous springbeauty, is a species of flowering plant in the family Montiaceae. It is a perennial herb indigenous to Alaska, British Columbia, Northwest Territories, and the Yukon of North America, westward to East Asia–Siberia. The perennial grows from a globose tuberous root to a height of 15 centimetres (6 in) and bears several hermaphrodite white flowers on stems bearing a single pair of petiolate cauline leaves. Its closest relative is probably Claytonia virginica.
Claytonia ogilviensis, common name Ogilvie Mountains spring beauty, is a plant endemic to the Ogilvie Mountains and the Dawson Range in the Yukon Territory of Canada. These mountains extend into Alaska, and one of the known populations is less than 1 km from the border, so it would not be surprising if the plant were to be found in Alaska as well.
Claytonia rosea, the Madrean springbeauty, is a diminutive perennial herb with long-lived, globose tuberous roots, reddish to green, long-tapered basal leaves, petiolate, cauline leaves, and light pink to magenta flowers. It is found in dry meadows in forests of ponderosa and Chihuahuan pines, and moist ledges of mountain slopes of the Beaver Dam Mountains of Utah, Colorado Front Range, and Sierra Madre Occidental, south and east to the Sierra Maderas del Carmen of Coahuila.
Androsace americana, synonym Douglasia arctica, known as the Mackenzie River dwarf primrose, is a species of flowering plant in the primrose family, Primulaceae. It is native to subarctic North America.
Claytonia arctica, commonly known as Arctic Spring Beauty, is a species of flowering plant native to Siberia including the Taimyr Peninsula and Wrangel Island and eastward to the Aleutians and Bering Sea islands of Alaska. A plant species of the circumpolar Arctic, it has been confused with Claytonia sarmentosa and C. scammaniana. A taxonomic revision including a lectotypification of Claytonia arctica was published in 2006.
Claytonia scammaniana is a species of flowering plant in the genus Claytonia, found in the mountains of Alaska and Yukon. The species has been subject of differing taxonomic opinions and confusion with Claytonia arctica and C. sarmentosa.A taxonomic revision including a review of previous studies of Claytonia scammaniana was published in 2006.
