}} ''Iris scariosa'' is a species in the genus ''Iris'', it is also in the subgenus of Iris. It is a rhizomatous perennial, from the mountainsides of Russia, Kazakhstan, Mongolia and China. It has sword-like, or sickle shaped, blue green or grey-green leaves, a short flowering stem, 3 or 4 membranous or semi-transparent flower bud leaves, 2 violet, reddish violet, lilac, blue-purple, or blue flowers in late spring, with yellow or white beards. It is cultivated as an ornamental plant in temperate regions. It was merged with another similar iris in the region, and ''Iris glaucescens'' became a synonym of ''Iris scariosa'', before being divided into two separate species again. Although some sources still call it the main species, despite a slight colour difference. ==Description== It is similar in form to ''Iris pumila''.〔(【引用サイトリンク】url=http://flower.onego.ru/other/iris/iris_ir.html )〕 It has a yellow-white,〔(【引用サイトリンク】url=http://www.flph.org/s/Irisscariosa )〕 thick, fleshy rhizome,〔〔(【引用サイトリンク】url=http://efloras.org/florataxon.aspx?flora_id=2&taxon_id=200028211 )〕 that is between in diameter.〔〔〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/article-chapitre-i-les-iris-rhizomateux-partie-2-105950846.html )〕 Under the rhizome are secondary stolon-like roots.〔 On top of the rhizome, are the yellow-white,〔 fibrous remains of last seasons leaves.〔 The creeping habit of the ground covering rhizomes,〔〔 makes small tufts of plants. It has ensiform (sword-shaped),〔〔〔British Iris Society (1997) 〕 sub-lanceolate,〔 or falcate (sickle-shaped),〔〔 blue-grey,〔 or grey-green leaves.〔〔 They can grow up to between long,〔〔〔 and between 1 and 1.8 cm wide.〔〔 They are generally longer than the flowering stem.〔〔 It has a flowering stem or peduncle, that can grow up to between tall.〔 It is normally tall.〔〔〔 The stems are leafless.〔〔 The stem has 3 or 4,〔〔〔 thin,〔 lanceolate,〔〔〔 spathes (leaves of the flower bud), they are (scarious) membranous,〔 and semi-transparent.〔〔James Cullen, Sabina G. Knees, H. Suzanne Cubey (Editors) 〕 They are long,〔〔〔 and 1.5–2 cm wide.〔〔 They have a reddish purple,〔〔 or lilac margins.〔 It has a brown-purple,〔 short perianth tube, which is about 1.5–4 cm long,〔〔〔 and slightly flared upward.〔〔 It also has short pedicels (flower stalks).〔〔〔 The stems hold 2,〔〔 terminal (top of stem) flowers, blooming in mid to late spring,〔〔 between April to May,〔〔〔 or May,〔 or May to June.〔Houlston and Stoneman (Publisher)〕 The unscented,〔 flowers are in diameter,〔〔〔 come in shades of violet,〔〔〔 reddish violet,〔〔〔 lilac,〔 blue-purple,〔〔〔 or blue.〔〔〔 Some sources also refer to rarely,〔 near white or yellow shaded flowers,〔〔〔 but these may, however only refer to ''Iris glaucescens''.〔 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 oblong,〔 or obovate shaped,〔〔 with a narrow claw (section near the stem).〔〔 They are long and 1.5 cm wide.〔〔〔 In the centre of each of the falls is a yellow 'beard' of hairs,〔〔 but it can be sometime white on the blade (the wide part of the petal).〔〔〔 The erect, oblanceolate shaped standards, are long and 0.5 cm wide.〔〔〔 It has 1.8 cm long stamens, 1.5 - 2.8 cm long ovary,〔 that is fusiform (spindle shaped),〔 and a lavender or pale purple style branch, that is 3.5 cm long.〔〔 After the iris has flowered, between mid to late summer,〔 or June to August,〔 or June to July.〔 It produces an ovoid,〔 or cylindrical spindle,〔 or oblong shaped seed capsule.〔 Which is long and 2.5–3 cm in diameter.〔 It has 6 visible veins or ribs.〔〔〔 The loculicidal (having compartments) capsule,〔 holds dark brown, round or elongated seeds, that are 4-5,5mm long and 2–3 mm wide.〔 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 scariosa」の詳細全文を読む スポンサード リンク
