''Iris confusa'' (also known as the Bamboo iris () is a species of iris, it is also in the subgenus of ''Limniris'' and in the Lophiris section (crested irises). It is a rhizomatous perennial plant, native to Western China. It has flowers which range from white to a soft lavender or pale blue in colour, with orange-yellow crests and purple dots. The plant's broad, shiny leaves are attached to bamboo-like stems. It is cultivated as an ornamental plant in temperate regions. ==Description== It is similar in form to ''Iris japonica'' and ''Iris wattii''. ''Iris confusa'' is larger than ''Iris japonica'' in all parts. Also the foliage of Iris japonica, has less attractive foliage then ''Iris confusa''. Compared to ''Iris wattii'', it is smaller and has smaller flowers.〔(【引用サイトリンク】url=http://www.herbs2000.com/flowers/i_ievansia.htm )〕 It has stout, creeping rhizomes.〔(【引用サイトリンク】url=http://efloras.org/florataxon.aspx?flora_id=2&taxon_id=200028161 )〕 They are short and bamboo-like.〔Simon Rickard 〕〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/article-chapitre-ii-iris-a-touffe-et-autre-partie3-106518511.html )〕 It also has short stolons.〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 On top of the rhizome are various scars and the remains of last seasons leaves.〔 The creeping habit eventually forms thick clumps.〔British Iris Society (1997) 〕〔Jenny Hendy and Annelise Evans (Editors)〕 It has 10 or more leaves that are grouped together as a fan-shape.〔〔〔〔〔 Unlike, most irises, the foliage is held on top of the bamboo-like stems.〔〔 So it more looks like a palm.〔 The sword-shaped,〔〔 or strap-shaped,〔〔 leaves are yellowish-green,〔〔 to bright green,〔 glossy (or shiny) on one side,〔〔 and glaucous on the other side.〔 They are lighter in colour than ''Iris japonica'',〔 and are normally thought to be evergreen.〔〔〔〔〔 The leaves can grow up to between tall and wide.〔〔〔〔〔 They veins can not be seen,〔 and the leaves ten to flop over.〔 It has flattened,〔 (bamboo) cane-like stems,〔Holly Kerr Forsyth (Editor) 〕 that can grow up to between tall.〔〔〔〔〔〔〔〔〔〔〔〔〔〔(【引用サイトリンク】url=http://www.senteursduquercy.com/iris-botanique/1435-iris-confusa.html )〕 It has 5-8 slender branches (or pedicels) near top of the plant.〔〔〔〔〔 The stiff pedicels are 1.5–2 cm long.〔 The stems can lie along the ground (after flowering) and can eventually produce roots, creating larger clumps of plants.〔〔 The stems have 4-6 spathes (leaves of the flower bud), which are generally membranous. They are 1.5 cm wide.〔 The stems (and the many branches) hold between 3 to 5 flowers,〔〔 in spring and early summer,〔〔〔〔〔〔 between April and May.〔〔〔〔〔〔 It can flower in early spring, if the plant is protected from the frost, in the UK.〔 The flowers are short lived, but since, the plant has many flowers, up to 75 flowers,〔 a continuous display can last for several weeks.〔〔 The flowers are in diameter,〔〔〔〔〔〔 and come in shades of soft lavender,〔〔〔〔〔〔〔 to pale blue, to white.〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔〔John Greenlee 〕 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 elliptical, have a rounded top (retuse), and have wide limb (section of the petal, closest to the stem), they are cm long and 1.5–2 cm wide.〔 On the blade is a yellow or yellow-orange ridge (or crest).〔〔〔〔〔〔〔〔 Surrounding the crest/ridge are orange-yellow,〔〔〔〔〔〔〔 or pale mauve,〔〔 or purple spots.〔〔〔〔〔〔〔 The standards are broadly lanceolate and have a rounded top (retuse). They are 2.5 cm long and 1 cm wide.〔 Both petals have wavy or scalloped edges.〔〔〔〔 It has pale blue style branches which have fringed lobes, and are 2 cm long and 8mm wide.〔〔 It has a 1.5 cm long perianth tube, 1.5 cm long stamens, 6mm long ovary and yellow anthers.〔 After the iris has flowered, it produces an ellipsoid seed capsule,〔〔〔 between May and July.〔 It is cm long and 1-1.4 cm wide and has 6 visible ribs.〔 Inside the capsule, are D-shaped,〔 dark brown 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 confusa」の詳細全文を読む スポンサード リンク
