''Iris filifolia'' is a species in the genus ''Iris'', it is also in the subgenus of Xiphium. Its name means 'threadleaved iris'.〔Ivan Nikolaevič Filipév, Jacobus Hermanus Schuurmans Stekhoven〕 Filifolia comes from the Greek words, 'fili' meaning thread-like and 'folia' meaning leaf. In Gibraltar, it is also known as the 'Narrow-leaved Purple Iris'. It is often mistakenly called 'Spanish Iris'.〔(【引用サイトリンク】 url=http://www.webster-dictionary.org/definition/Iris%20filifolia )〕 The Spanish Iris is Iris xiphium. In 1842, it was first described in 'Voyage botanique en Espagne' Vol 2, page602.〔(【引用サイトリンク】 url=http://apps.kew.org/wcsp/namedetail.do?name_id=321817 )〕 Dykes notes that this description is incorrect. It was also described in Curtis's Botanical Magazine No.5929 as 'Xiphion filifolium'. It was recorded in the Catalogue of Life in 2011. ==Habit== It flowers between March and June. Normally more than 2 flowers per stem.〔(【引用サイトリンク】 url=http://iridaceae.e-monocot.org/classification/iris-filifolia-0 )〕 When the flowering shoot comes out of the ground it is covered in a purple or white blotched sheath.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 These then open up to revel red-purple flowers with orange spots on the falls.〔 It normally reaches a height of 10-16 inches (or 25–40 cm).〔 But can reach up to 45 cm tall.〔 The 3mm wide leaves〔 appear in the autumn.〔 It is known to be toxic like other bulbs in the genus.〔(【引用サイトリンク】url=http://www.pfaf.org/user/Plant.aspx?LatinName=Iris+filifolia )〕 It is best grown in a bulb frame in the UK. 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 filifolia」の詳細全文を読む スポンサード リンク
