It is a rhizomatous perennial, from Tibet and China, with pale blue, blue-purple, purple, violet or white flowers. It is cultivated as an ornamental plant in temperate regions. ==Description== It has short rhizome with a few branches.〔(【引用サイトリンク】url=http://www.flph.org/s/Iris subdichotoma )〕〔(【引用サイトリンク】url=http://tl.swewe.net/word_show.htm/?204963_1&Zhongdian_Iris )〕 Below is thick roots.〔(【引用サイトリンク】url=http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200028217 )〕 On top of the rhizomes are the brown, fibrous remains of last seasons leaves, surrounding the new leaves.〔〔〔 It has grey-green, sword-shaped and slightly curved leaves.〔〔〔 They grow up to between long and 1–2 cm wide.〔〔〔 They do not have any mid-veins.〔〔〔 The leaves are generally short than the flower stems. It has flowering stems that can grow up to between long.〔〔〔〔 The stems have between 2-5 branches.〔〔〔 The plant is very similar in form to ''Iris dichotoma'' but only smaller.〔 The stems have 3-5 green, spathes (leaves of the flower bud), which have membranous margins.〔〔〔 They are long and 7-8mm wide.〔〔〔 The bracts are similar in size to ''Iris dichotoma''.〔 The stems (and branches) hold between 2 to 4 flowers, between June to August.〔〔〔 But normally in June.〔〔 Leading from the spathes are stiff, pedicels (or peduncles), that are between long.〔〔〔 The flowers are in diameter,〔〔〔 and come in shades of pale blue,〔 blue-purple,〔〔 purple,〔〔 or violet.〔〔〔 Later, a white flowering form was found and then was published and named as ''Iris subdichotoma f. alba'' Y. G. Shen, in 'Acta Bot. Yunnan' Vol.26 Issue5 page492 in 2004).〔 Although this is now classified as a synonym of ''Iris subdichotoma''.〔 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 oblanceolate, and 4 cm long and long.〔〔〔 The falls have a central yellow crest.〔 The standards are narrow and oblanceolate, and 3 cm long and 4 mm wide.〔〔〔 It has a 2 cm long perianth tube, 2.2 cm long stamens, 1.5 long and 0.5 cm wide, fusiform (spindle-shaped) ovary and 3 cm long style branches.〔〔〔 The styles branches have narrowly triangular lobes.〔〔〔 It also has filaments that are longer than the anthers.〔〔 After the iris has flowered, it produces a cylindric seed capsule,〔 between July to September, that is long and 1 cm wide.〔〔〔 It has 6 longitudinal ribs.〔〔〔 The capsule when ripe, splits a third of the way down, releasing the seeds.〔〔〔〔 The seeds are 7.5 - 8.5 mm wide, maroon-brown and have a small wings.〔〔〔〔 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 subdichotoma」の詳細全文を読む スポンサード リンク
