''Clarkia'' is a genus within the flowering plant family Onagraceae. Over 40 species are currently classified in ''Clarkia''; almost all are native to western North America, though one species (''Clarkia tenella'') is native to South America. Clarkias are typically annual plants, growing to a height of less than 1.5 metres. Their leaves are small and simple, from 1 to 10 cm in length depending on the species. Their flowers have four sepals and four petals. Several members of the genus are sometimes referred to by the common name "Godetia", including ''Clarkia amoena'', ''Clarkia affinis'', and ''Clarkia lassenensis'' (the Lassen Godetia). This is because they were formerly classified in a genus called ''Godetia'', which is no longer recognised since its members have been absorbed into the ''Clarkia'' genus. Older sources may still use ''Godetia'' as a genus name. The genus was named in honour of the explorer Captain William Clark. The Royal Navy had a warship called HMS ''Clarkia'', a flower class corvette. == Cultivation == Some species are popular garden plants, for example the Mountain Garland, ''Clarkia unguiculata'', the Redspot Clarkia, ''Clarkia speciosa'', Farewell to Spring, ''Clarkia amoena'' and ''Clarkia bottae''. There are cultivated varieties of some of these species. 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「Clarkia」の詳細全文を読む スポンサード リンク
