''Iris marsica'' is a species in the genus ''Iris'', it is also in the subgenus of Iris. It is a rhizomatous perennial, from the Apennine Mountains, in Italy. It has glaucous, sickle-shaped or curved, light green leaves, slender stem with 2 branches, and 3 violet, light blue violet, dark violet, and dark purple flowers. It was only found and described since 1973, and is not yet in general cultivation. It was once thought to be a form of Iris germanica, but has different morphological characteristics and different chromosomal differences. ==Description== It is similar in form to Iris germanica,〔(【引用サイトリンク】url=http://irisbotanique.over-blog.com/article-chapitre-i-les-iris-rhizomateux-partie-2-123788250.h )〕 but it has more curved leaves (or sickle-shaped,) greener, and longer leaves, the stem is less glaucous,〔British Iris Society (1997) 〕 and it has less scarious (membranous) spathes.〔 It has a thick rhizome, with many stoloniferous and fibrous branches. The rhizomes grow at ground level.〔 It has herbaceous,〔(or deciduous),〔 falcate (sickle-shaped),〔〔 light green and slightly glaucous leaves.〔 They can grow up to long.〔 They often have 2-3 basal (rising from the rhizome) leafs, with one sheathing the stem.〔 It has a flattened stem,〔 or peduncle, that can grow up to between tall.〔〔 It has 2 short branches,〔〔〔 (or pedicels), the lowest branch is similar in length to the bract.〔 The other branch, appears from the mid-point on the stem.〔 The stem has 2-3 green, marked with purple, slightly inflated, rounded, spathes (leaves of the flower bud). They are scarious (along the top part of the leaf), at blooming time.〔 The stem (and the branches) hold up to 3 flowers,〔 in early season,〔 in April,〔 May,〔 or between May and June.〔(【引用サイトリンク】url=http://www.villalago-abruzzo.com/villalago_flora_fauna_PNALM.htm )〕〔(【引用サイトリンク】url=http://www.goingthroughitaly.com/558/the-national-park-of-abruzzo/ )〕 The slightly fragrant,〔 flowers come in shades of violet,〔〔〔 light blue violet,〔 dark violet,〔〔 and dark purple.〔 It sometimes has bi-toned flowers.〔〔 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 obovate or cuneate (wedge shaped), and long and 4.5 cm wide.〔 They have dark veining on the haft (near to the stem),〔〔〔 They also sometimes curl under.〔 In the centre, of the falls is a 'beard', or line of white hairs, tipped with yellow.〔〔〔 The standards are elliptic shaped, with a narrow haft, and long and 3.8 cm wide.〔 It has 3.8 cm long perianth tube, the style branch is normally, white with violet crest. The crest is toothed (dentate). It has white or blue filaments, and pale cream pollen. It has a triangular in section ovary.〔 After the iris has flowered, it produces a seed capsule, which has not been described. 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 marsica」の詳細全文を読む スポンサード リンク
