}} ''Iris imbricata'' is a species in the genus ''Iris'', it is also in the subgenus of Iris. It is a rhizomatous perennial, from the Caucasus mountains, within Iran, Armenia, Azerbaijan and Georgia. It has broad, sword-like, yellow green or light green leaves, slender stem with branches, inflated and overlapping green spathes, and 2 5 yellow, pale yellow or greenish yellow flowers. ==Description== It is similar in form to ''Iris taochia'', ''Iris schachtii'' and the yellow form of ''Iris purpureobractea'' (from Turkey).〔Basak Gardner & Chris Gardner 〕 It is also similar to ''Iris albertii'',〔(【引用サイトリンク】url=http://www.agbina.com/site.xp/052056055124052052055.html )〕 but with yellow flowers. It as a stout rhizome,〔Richard Lynch and Henry Ewbank 〕〔(【引用サイトリンク】url=http://www.vivaiocorazza.com/en/products/320-iris-imbricata-azerbaijan-.html )〕 that can form dense clumps of plants. It has deciduous (in Winter),〔 erect, ensiform (sword-like),〔〔 yellow green, or light green, or grey-green leaves.〔〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 The outer and first leaves, are normally very blunt and rounded. This led to early specimens of the plant were renamed at Kew as ''Iris obtusifolia'', this was later classified as a synonym of 'Iris imbricata'〔 The broad leaves,〔〔〔 can grow up to between long, and between 2 to 3 cm wide.〔 It has a slender stem or peduncle, that can grow up to between tall. They are often branched,〔〔〔 with short branches.〔 The stem has oval,〔 or oblong shaped,〔 green,〔 or pale green,〔〔 inflated,〔〔〔 spathes (leaves of the flower bud). They are also tightly imbricated, or overlapping,〔〔 and transparent,〔〔 or membranous at the tip of the bract.〔〔〔 They look similar in form to translucent green pea pods.〔 The stems (and the branches) hold numerous,〔 between 2 to 5 flowers,〔〔〔 in spring or summer,〔 between April and May,〔 May,〔(【引用サイトリンク】url=http://flower.onego.ru/other/iris/iris_ir.html )〕 or between May and June.〔〔 The large,〔〔 flowers are in diameter,〔〔〔 They are larger than ''Iris flavescens'' (a synonym of Iris variegata L.), and another yellow flowering iris.〔 They come in shades of yellow, from pale yellow,〔〔〔 greenish yellow,〔〔〔 (or chartreuse,〔) to bright yellow,〔〔 or sulphur yellow.〔 Very rarely, there is a purple form,〔 and also blue forms,〔 were noted by Rodionenko. Like other irises, it has 2 pairs of petals, 3 large sepals (outer petals), known as the 'falls' and 3 inner, smaller petals (or tepals), known as the 'standards'. The falls are obovate or cuneate shaped,〔〔 and long.〔 They often curl under,〔 or are reflexed.〔Kelly Norris 〕 They have 'hafts' (section near to the stem) that are veined with brown,〔〔〔 or brownish purple.〔〔 In the centre of each of the falls, is a white beard tipped with yellow,〔〔 or yellow,〔〔 or dark yellow beard.〔〔 The standards are obovate, and broader than the falls.〔 It has style branches that are 2.54 cm long.〔 It has a short perianth tube,〔 at under 2.54 cm long.〔 After the iris has flowered, it produces a seed capsule, in late July.〔 The capsule and seeds have not been described. 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 imbricata」の詳細全文を読む スポンサード リンク
