}} ''Iris potaninii'' is a species in the genus ''Iris'', it is also in the subgenus of Iris and in the ''Psammiris'' section. It is a rhizomatous perennial, from Siberia in Russia, Mongolia and China. It is a dwarf plant, having either subterranean or very small stems, long thin leaves and yellow, or dark violet to purplish blue flowers. It is cultivated as an ornamental plant in temperate regions. ==Description== Similar in form to ''Iris tigridia'' (within ''Pseudoregalia section'') and ''Iris bloudowii'' (another ''Psammiris section'' iris), but differs from bloudowii, in having an ob-conical, not prostate rhizome. It differs from tigridia by having old leaf fibres on the rhizome.〔British Iris Society (1997) 〕 It also differs from ''Iris tigridia'' in leaf form, ''Iris potaninii'' has rounded ended leaves, which do not end in a point. It has thick, short and tough rhizomes.〔〔(【引用サイトリンク】url=http://efloras.org/florataxon.aspx?flora_id=2&taxon_id=200028197 )〕〔(【引用サイトリンク】url=http://irisbotanique.overblog.com/categorie0.html&usg=ALkJrhh70LNmXSsW7XWSPOAq9g9rjg4IpQ )〕〔(【引用サイトリンク】url=http://flower.onego.ru/other/iris/iris_hum.html )〕 Under the rhizomes, are thick, fleshy and yellowish, secondary roots.〔〔〔〔 On top of the rhizome, are the curled, fibrous remains of last seasons leaves.〔〔〔〔〔 It has linear basal (growing from the base) leaves,〔〔〔〔 which are not pointed at the ends (or obtuse).〔〔〔 They can grow up to between long and 0.2-0.4 cm wide, at blooming time.〔〔〔〔 The leaves then lengthen,〔〔 and by the time the iris has seed capsules, they are between long and 0.3-0.4 cm wide.〔 It is a dwarf plant,〔 having either subterranean,〔〔〔 or very small stems or pedicels.〔 They can reach up to between long.〔 The pedicel (or dwarf stem) has 2 narrow, lanceolate (or oblong-lanceolate,〔) and (scarious) membranous spathes or bracts (leaves of the flower bud).〔〔〔 They are long and 0.6 cm wide.〔〔 The stem (or pedicel) holds 1 terminal (top of stem) flower,〔〔 between April to May (in Russia),〔 or May to June.〔〔〔 The flowers are in diameter, come in yellow,〔〔〔 or dark violet to purplish blue shades.〔〔〔〔〔 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 (in shape),〔 with markings or veins around a central yellowish or whitish beard.〔〔〔〔〔 They are long and 1.2-1.5 cm wide,〔 and have curled up edges.〔〔 The erect standards are oblanceolate,〔 and are long and 0.8-1.0 cm wide.〔〔 They also have curled up edges.〔〔〔 It has a long perianth tube,〔〔 which is thread-ilke.〔 It also has 1.5 cm long stamens, purple anthers and a 0.7 cm long (spindle-shaped) ovary.〔〔 It has a 2.8 cm long and 6mm wide style branch, which has a flat crest and toothed edges.〔〔 After the iris has flowered, between June or July (in Russia),〔 or between July and September,〔〔 it produces an ellipsoid seed capsule.〔 Which is long and between 1.3-1.5 cm wide, and has 6 longitudinal ribs and a short beak appendage (at the top).〔〔〔 It dehisces (splits open) from the middle of the capsule.〔 Inside the capsule, are 3mm in diameter, flattened globular, or pyriform (pear shaped), wrinkled, and reddish 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 potaninii」の詳細全文を読む スポンサード リンク
