''Limnanthes floccosa'', or woolly meadowfoam, is a species of meadowfoam found in Northern California and Southern Oregon, in the United States. Most of the subspecies have highly restricted distributions and are listed as critical or endangered.〔(【引用サイトリンク】publisher=Oregon Department of Agriculture )〕〔(【引用サイトリンク】publisher=Oregon Department of Agriculture )〕〔(【引用サイトリンク】publisher=United States Fish and Wildlife Service )〕 Perhaps the most familiar subspecies of woolly meadowfoam is ''californica'', not because it is the one most often seen (it is very inconspicuous), but because this taxon has been the focus of a significant conflict. The subspecies is found only among a dozen or so populations in Butte County, California, and is legally protected as endangered. Conflict has arisen between those who would protect the few remaining populations and those who would rather use its critical habitat for economic activities. Certain subspecies of ''L. floccosa'' have been used to improve a meadowfoam cultivar derived from ''Limnanthes alba''. The crop is grown for its seed oil, which contains long chain fatty acids (greater than 20 carbons), has high oxidative stability, does not have any odor and is highly emollient. The oil is currently used in cosmetics manufacturing. ''Limnanthes'' is cultivated in the Willamette Valley of Oregon and elsewhere. ==Taxonomy== Woolly meadowfoam ''Limnanthes floccosa'' is a member of the genus section ''inflexae'' (wherein the petals curve over the fruit when it is mature). Most populations of this species are at least partially autogamous (self-pollinating). The species is easily distinguished from other members of ''inflexae'' by the fact that its petals are not much longer and often shorter than the sepals. The flowers mostly remain closed even at maturity, in contrast to Table Mountain meadowfoam (''Limnanthes douglasii'' ssp. ''nivea''), for example. The most widespread subspecies (''floccosa'') occurs in both California and Oregon. Two subspecies (''pumila'' and ''grandiflora'') are endemic to southern Oregon. The ''Jepson Manual'' (a flora of California) recognizes only one California endemic subspecies (''californica'') but the Flora of North America recognizes a second (''bellingeriana''). (The Jepson Manual notes a putative subspecies (''bellingeriana'') has been "reported from Cascade Range Foothills but requires further study".) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Limnanthes floccosa」の詳細全文を読む スポンサード リンク
