It is a rhizomatous perennial, from eastern Russia, China, and Mongolia. It has narrow and linear light green leaves, short slender stem and pink-purple flowers. It is cultivated as an ornamental plant in temperate regions. DescriptionIt is similar in form to Iris tigridia but differs in the leaves, being narrower on Iris tigridia and Iris ivanovae having smaller flowers.[2] It has a thick, dark grey rhizome, that is about 2 – 4 mm in diameter.[3][4] Below the rhizome, it has wrinkled dark grey secondary roots.[3][4] The rhizome, is covered in the remains of light brown or grey dead leaves.[3][4] The radical leaves are light green,[4] narrow, linear, with 2–3 prominent veins.[3][4] They can grow up to between {{convert|10|-|25|cm|0|abbr=on}} long,[3][4] and 1–2.5 mm wide.[2][5] It has a slender stem, that can grow up to between {{convert|0.5|-|10|cm|0|abbr=on}} tall.[3][4][6] The stem has 2 green, narrow, lanceolate, spathes (leaves of the flower bud), that are {{convert|2.5|-|4|cm|0|abbr=on}} long and between 0.5 - 0.7 cm wide.[2][4] The stems hold 1 terminal (top of stem) flower, blooming in early May.[3][4][6] The flowers are {{convert|2.5|-|3.5|cm|0|abbr=on}} in diameter,[2][3][4] they come in shades of pink-purple.[3][4] They have dots and dashes markings on the flowers.[3][4] 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'.[7] The falls are {{convert|5|cm|0|abbr=on}} long,[3] and 0.8–1 cm wide, with a beard of clavate hairs in the middle.[4] They narrow to a thread-like claw (near to the stem).[2][4] The standards are lanceolate, with a notch at the top of the petal.[3][4] It has a triangular shaped ovary,[3][4] it has a 1.5–2 cm long perianth tube, that is between 0.5–1 mm in diameter and yellow anthers.[4] After the iris has flowered, in late June and early July,[4][6] it produces an oblong-oval seed capsule,[2][3][4] which has a small nose or sprout.[3][4] Inside, the capsule are brown, wrinkled and reticulate (resembling a net) seeds.[3][4] BiochemistryAs most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[7] It has a chromosome count of 2n=20 or 2n=40.[5] Specimens from Chitinskaya Oblast in Russia, were found to have a chromosome count of 2n=20.[8] TaxonomyIt is sometimes known as Iris invanova in Russia.[6][9][10] It is written in Russian Cyrillic script as Касатик Ивановой.[11] It is also commonly known as 'fine-leaved iris' (in Russia).[59][12] It is not known what the Latin specific epithet ivanovae actually refers to. But it has also been used by Nothobranchius ivanovae Valdesalici, 2012 (a fish), Polypogon ivanovae Tzvelev (a grass) and Oncopsis ivanovae (a leaf hopper insect). It was first published and described by Vladimir Doronkin in 'Flora Sibiri' (Fl. Sibir. – Arac.-Orchidac.) on page 117 in 1987.[2][13][14] It has not yet been verified by United States Department of Agriculture and the Agricultural Research Service as of 6 August 2015. Distribution and habitatIris ivanovae is native to central Asia, including U.S.S.R., China and Mongolia.[13]RangeIt is found in Russia, within Siberia,[4][6][10] Buryatia (republic) (including Trans-Baikal,[3]) and Chita Oblast regions.[3][4][10] It is found in China,[ within several Provinces of China, (including Jilin, Nei Mongol and Shanxi).][It is also found in Mongolia.][ Including being found in Selenge Province of the Khuder District.][{{cite journal |last=Doronkin |first=Vladimir |last2=Shaulo |first2=Dmitry |last3=Han |first3=Irina |last4=Vlasova |first4=Natalya |last5= Ivleva |first5=Victoria |last6= Enkhtuya |first6=Luvsanbaldan |last7= Munkh-Erdene |first7=Tovuudorj |last8= Ochgerel |first8=Nanjidsuren |last9=Munkhjargal |first9=Battseren |date= 2015 |title=New records for the flora of Selenge Province (Mongolia) |url=http://skvortsovia.uran.ru/2015/2102.pdf |format=PDF |journal=Skvortsovia |publisher= |volume=2 |issue=1 |pages=8–27 |doi= |accessdate=20 July 2015}}]
