Claytonia Acutifolia
''Claytonia arctica'', the 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.Miller, J. M. and K. L. Chambers. 2006. Systematics of ''Claytonia'' (Portulacaceae).

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Claytonia
''Claytonia'' (spring beauty) is a genus of flowering plants native to Asia, North America, and Central America. The vitamin-rich leaves can be eaten raw or cooked, and the tubers can be prepared like potatoes. Description The plants are somewhat fleshy and only a few centimeters in height. The flower heads are about in diameter. Taxonomy The genus was formerly included in the purslane family (Portulacaceae), but with the adoption of the APG IV system, in 2009 it was moved to the family Montiaceae. A number of the species were formerly treated in the related genus '' Montia''. A comprehensive scientific study of ''Claytonia'' was published in 2006. Species , Kew's Plants of the World Online lists 33 accepted species: Etymology The genus is named after John Clayton, who collected specimens of various plants in North America and distributed them to botanists in Europe. Distribution and habitat The genus is primarily native to the mountain chains of Asia and North Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
