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,[1][2] in the mesic understory of deciduous or coniferous forests.Шаблон:Sfn The genus, first described by Constantine Samuel Rafinesque in 1818,[3] was named for DeWitt Clinton (1769–1828), a naturalist and politician from the U.S. state of New York.[4][5] For this reason, plants of the genus are commonly known as Clinton's lily. The common name bluebead (and by extension bluebead lily) refer to the distinctive fruit of members of the genus.[6] Since fruit color varies somewhat across species, the common name bead lily is used as well.[7]
Description
The genus Clintonia is morphologically diverse.Шаблон:Sfn Species are herbaceous perennial plants growing from rhizomatous underground stems with thin, fibrous roots. They grow from 1.5 to 8 dm tall. They have 2 to 6 basal leaves arising from the rhizome crown, the basal leaves are sessile and sheathing, and the cauline leaves have a stalk. The blade of each leaf has a prominent central vein and entire margins, and the bottom ends are obovate to oblanceolate in shape. The leaf apex is acute to abruptly short-acuminate, often mucronate (ending abruptly in a short sharp point). The inflorescences are terminal, and the flowers are arranged into short racemes or umbel-like clusters, with 1 to 45 flowers. The flowers have 6 tepals with nectaries present. The stamens are inserted at the base of the perianth, and the anthers are oblong-obovate to oblong-linear shaped. The rounded to cylinder shaped ovary is superior with two chambers (sometime three). Each chamber produces 2 to 10 ovules. The smooth fruits are berry-like, round to egg-shaped, metallic blue to black in color. Four to thirty seeds are produced in each fruit and the seeds are shiny brown, round and the ends are angled with 2 or 3 faces.[8][9]Шаблон:Sfn

POWO also accepts the infraspecies Clintonia udensis var. alpina (Kunth ex Baker) H.Hara but some authorities do not accept this name.[10]
Molecular phylogenetic studies demonstrate two major disjunct clades, in eastern Asia and in North America respectively, and with the latter in East and in West. Within the family Liliaceae, Clintonia is a sister group to Medeola.Шаблон:Sfn
Distribution
There are five species of Clintonia, four in North America and one in Asia.
North America
Two species of Clintonia occur in western North America:
- C. andrewsiana is localized along the West Coast of the United States, from central California to southwestern Oregon.[11]
- C. uniflora ranges from central California to southern Alaska, extending east into Alberta and Montana.[12]
The remaining two species are found in eastern North America:
- C. borealis is wide-ranging, from Newfoundland and Labrador to Manitoba, extending south across New England and the Great Lakes region into the Appalachian Mountains.[13]
- C. umbellulata is endemic to the Appalachian Mountains in the eastern United States.[14]
Canada
- Alberta: C. uniflora

- New Brunswick: C. borealis
- Newfoundland and Labrador: C. borealis

Ecology
Spring blooming.Шаблон:Sfn
Cultivation
Clintonia species are cultivated as garden subjects in shade gardens, grown for the glossy foliage, small lily-like flowers, and blue fruits, and their ability to live in heavy shade. They grow best in cool, organic-rich, acid soils that retain moisture and when grown well form dense slowly spreading clumps.[17]
