''Iris mesopotamica'' ('Mesopotamian Iris') is a species in the genus ''Iris'', it is also in the subgenus of Iris. It is a rhizomatous perennial, from the middle East, within the countries of Turkey, Syria and Israel. It has linear, grey-green or green broad leaves, tall stem with 2-3 branches, holding up to 9 scented flowers, in shades of violet, purple, lavender blue and light blue, with a yellow and white or orange and white beard. It is listed as a synonym of ''Iris germanica'' in some sources. It is cultivated as an ornamental plant in temperate regions, including being planted in graveyards and cemeteries. ==Description== It is often confused with ''Iris trojana'' (now classed as a synonym of ''Iris germanica'') and ''Iris cypriana''.〔 It is also similar in form to ''Iris cypriana'' but outer bract (spathe) is brown and papery in the upper third only.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 It is a geophyte,〔(【引用サイトリンク】url=http://www.wildflowers.co.il/english/plant.asp?ID=39 )〕 that has thick rhizomes,〔(【引用サイトリンク】url=http://www.cgf.net/plants.aspx?genus=IRIS )〕 which are stoloniferous, and semi-buried in the ground.〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/article-chapitre-i-les-iris-rhizomateux-partie-2-123788250.h )〕 It has linear,〔 green,〔British Iris Society (1997) 〕〔(【引用サイトリンク】url=http://www.vivaiocorazza.com/en/products/599-iris-mesopotamica.html )〕 or grey-green,〔〔 glaucous leaves.〔〔〔 The sheathing leaves,〔 can grow up to between long,〔〔 and 5 cm wide.〔〔 The leaves are wider than ''Iris cypriana''. It has a tall stem, or peduncle, that can grow up to between tall.〔Kelly Norris 〕 It has 2 or 3 branched stems.〔 The stem has broad,〔〔 spathes (leaves of the flower bud), which are green green in the lower half,〔 and (scarious) membranous or brown and papery,〔 in the upper third of the leaf.〔 The stems (and the branches) hold between 3 to 8,〔〔 or 9 flowers.〔 Each stem carries 2-3 flowers,〔 at the terminal end of each branch,〔 there is always a single flower per stem.〔 It blooms early in the season, between late spring and early summer,〔 between May,〔〔(【引用サイトリンク】url=http://www.tiuli.com/flower_info.asp?lng=eng&flower_id=425 )〕 and June.〔〔 The large flowers, are scented,〔〔〔 and come in shades of violet,〔〔〔 purple,〔〔〔 lavender blue (similar in shade to ''Iris junonia''),〔〔 and light blue.〔〔 There are occasionally bi-toned flowers.〔 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 (wedge shaped),〔 with a white haft (section closest to the stem),〔 that has bronzy purple veins,〔〔〔 or lines.〔 In the centre of the fall, is a row of hairs called a beard, which are yellow,〔 or orange yellow,〔 at the base, turning white at the front of the petal.〔〔〔〔 The standards are obovate or unguiculate (claw shaped), they are paler than the falls,〔〔 and have a pale haft that is also marked with bronzy-purple.〔 It has a long perianth tube,〔〔 which is wider and shorter than the perianth tube of ''Iris cypriana''.〔 It has a rounded ovary, blue-purple style arms, violet crests, white filaments and cream anther.〔 After the iris has flowered, it produces an oblong or trigonal seed capsule, that is long. Inside the capsule, are large, pyriform (pear-shaped), brown wrinkled seeds.〔 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 mesopotamica」の詳細全文を読む スポンサード リンク
