''Iris heweri'' is a species in the genus ''Iris'', it is also in the subgenus of Iris and in the ''Regelia section''. It is a rhizomatous perennial, from Afghanistan. It has tall, green curved leaves, tall slender stems and purple blue or violet-blue flowers, with white and purple or lilac beard. It is cultivated as an ornamental plant in temperate regions. ==Description== It is similar in form to ''Iris falcifolia'' (in the ''Hexapogon Section'') but differs in having a looser rhizome system and the leaves are also different.〔British Iris Society (1997) 〕 It has a small and slender rhizome, that is 0.5 cm in diameter.〔〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/categorie-0.html&usg=ALkJrhh70LNmXSsW7XWSPOAq9g9rjg4IpQ )〕 It has several stolons (branches), that are between 1 – 5 cm long.〔 On top of the rhizome, are the fibrous remains of last seasons leaves.〔 It has 4-7,〔 grey-green,〔 or green leaves.〔〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 They are falcate (or sickle shaped),〔〔〔(【引用サイトリンク】url=http://encyclopaedia.alpinegardensociety.net/plants/Iris/heweri )〕 with membranous margins.〔 The leaves can grow up to long,〔 they are shorter (than the flowering stem) at the time of blooming.〔〔 They are between 0.2 – 0.5 cm wide.〔〔〔〔 It has a stem that can grow up to between tall, but occasionally they can reach up to tall.〔〔〔 The stem has spathes (leaves of the flower bud), that are long.〔 The stems hold 1 - 3 terminal (top of stem) flowers,〔〔 blooming late spring,〔 or May.〔 The flowers are in diameter,〔〔〔 come in shades of purple blue,〔〔〔〔 or violet-blue flowers 〔 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 elliptic and oblanceolate shaped and long,〔 and between 1.25 – 1.5 cm wide.〔 It has a sharply reflexed blade and dense central beard of white hairs, which are tipped in purple or lilac.〔 The haft (section closest to the stem) is whitish veined with purple.〔 The erect standards are narrowly obovate and long,〔 and between 1 – 1.25 cm wide.〔 It has a cuneate (wedge shaped) haft with sparse beard extending onto blade.〔 It has a 1.5 cm long perianth tube and a 1.4 cm long pale purple style, that is elliptical (in shaped) and has slightly wavy margins. It is also tri-lobed and the lobs are triangular and 0.9 cm long.〔 It has a 0.5 cm long white filament, 1.1-1,3 cm long anthers and creamy white pollen.〔 After the iris has flowered, it produces a seed capsule, which is 3.5 cm long and 1.5 cm wide. It has a short pedicel and the remains of the perianth tube can still be found at the top of the capsule. Inside, are 0.4 cm long and 0.25 cm wide, dark brown seeds, which are rough coated with white aril (appendage).〔 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 heweri」の詳細全文を読む スポンサード リンク
