''Iris series Tripetalae'' is a series of the genus ''Iris'', in the subgenus of ''Limniris''. The series was first classified by Diels in 'Die Natürlichen Pflanzenfamilien' (Edited by H. G. A. Engler and K. Prantl) in 1930. It was further expanded by Lawrence in Gentes Herb (written in Dutch) in 1953.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 The name of the series comes from the three petals of the flowers of the species in the series. It has been theorised that due to that when the ice caps were formed in the last ice age, this split ''Iris tridentata'' from other forms in North America.〔British Iris Society (1997) 〕 Most have small standards and violet-blue flowers, 〔〔(【引用サイトリンク】 url=http://www.kevockgarden.co.uk/store/iris-tripetalae-series-(iris-hookeri-and-relatives) )〕 with darker veins on the large falls.〔 Only, ''Iris setosa'' is in cultivation, in the UK,〔 and in the US.〔(【引用サイトリンク】 url=http://www.herbs2000.com/flowers/i_itripetala.htm )〕 They prefer lime-free soils and moist conditions.〔 They are often used in hybridising with species of ''Iris'' series ''Sibiricae'' or ''Iris'' series ''Californicae''.〔 Includes; *''Iris hookeri'' Penny – Hooker's Iris *''Iris setosa'' Pallas ex Link – (Beachhead Iris) *''Iris tridentata'' Pursh – Savanna Iris ==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「Iris series Tripetalae」の詳細全文を読む スポンサード リンク
