''Melanthium'' is a genus of herbaceous perennial plants native to North America. They are closely related to ''Veratrum'', and in fact are included in that genus by some authors. The distinction between ''Melanthium'' and ''Veratrum'' is based on various morphological traits, but it is not yet clear where the line is best drawn.〔(【引用サイトリンク】 ''Melanthium'' Linnaeus )〕 They contain alkaloids similar to those found in ''Veratrum'' and are thus assumed to be poisonous.〔 == Species == The (World Checklist ) considers ''Melanthium'' as a synonym of ''Veratrum'', and accepts no species as members of ''Melanthium.'' (Tropicos ) does likewise, adding that proposals have been made to reject the name ''Melanthium'' entirely.〔Zomlefer, W. B., W. S. Judd & K.N. Gandhi. 2010. (1928) Proposal to conserve the name ''Veratrum'' against ''Melanthium'' (Melanthiaceae). Taxon 59(2): 644-645. 〕 (The Plant List ) and (Flora of North America ), however, do accept the following names in ''Melanthium:'' * ''Melanthium latifolium'' or ''Veratrum hybridum'' - eastern United States from Connecticut to Alabama and Arkansas * ''Melanthium parviflorum'' or ''Veratrum parviflorum'' - southern Appalachians from Virginia to Alabama * ''Melanthium virginicum'' or ''Veratrum virginicum'' - eastern United States and Mississippi Valley from New York to Iowa south to Texas and Florida * ''Melanthium woodii'' or ''Veratrum woodii'' - central + southeastern United States 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「Melanthium」の詳細全文を読む スポンサード リンク
