''Emilia fosbergii'' is a species of plants in the sunflower family.〔(Nicolson, Dan Henry 1975. Phytologia 32(1): 34 )〕〔(Tropicos, ''Emilia fosbergii'' Nicolson )〕〔Nicolson, D. H. 1980. A summary of cytological information on Emilia and the taxonomy of four Pacific taxa of ''Emilia'' (Asteraceae: Senecioneae). Systematic Botany 5: 391–407.〕 ''Emilia fosbergii'' has been collected in many places for many years, the specimens regarded as belonging to ''E. coccinia, E. sagittata, ''or'' E. javanica.'' A reexamination of a large number of specimens led Nicolson to recognize it as a distinct species in 1975. He named the species in honor of Francis Raymond Fosberg.〔(Nicolson, Dan Henry 1975. Phytologia 32(1): 33-34 )〕 ''Emilia fosbergii'' is widely distributed in tropical and semitropical parts of the world: Africa, South and Southeast Asia, northern Australia, North and South America, and various oceanic islands. Its region of origin is the subject of some dispute; some say it is native to Africa, while others say Asia or South America.〔(Flann, C (ed) 2009+ Global Compositae Checklist )〕〔(Flora of North America, Florida tasselflower, ''Emilia fosbergii'' Nicolson, Phytologia. 32: 34. 1975. )〕〔(Flora of China Vol. 20-21 Page 543 缨荣花 ying rong hua ''Emilia fosbergii'' Nicolson, Phytologia. 32: 34. 1975. )〕 It is reportedly naturalized in scattered locations in the United States, including Puerto Rico, and the Virgin Islands.〔〔(Biota of North America Program 2013 county distribution map )〕 Common name for the species in the United States is Florida tasselflower. ''Emilia fosbergii'' is an annual herb up to 100 cm (40 inches) tall. It generally has only one central stem, sometimes branching but sometimes not. Each flower head can contain more than 60 pink, purple, or red disc florets but no ray florets.〔(Flora of North America, Florida tasselflower, ''Emilia fosbergii'' Nicolson )〕 ==References== 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「Emilia fosbergii」の詳細全文を読む スポンサード リンク
