Təpə yarpaqları yaşıl, göyümtül, təpə hissəsi pərdəli, çiçəkdən qısadır, çiçəkyanlığının borucuğu 5 dəfə yumurtalıqdan uzundur, çiçəkyanlığı bənövşəyi, xarici tərəfi (3,5) 4,5 -5,5 sm uzunluğundadır. Təpə hissəsi dairəvidir; çiçək yanlığının daxili tərəfi yumurtavari və ya uzunsovdur. Sütuncuğun kənarı çiçəkyanlığının xarici kənarından qısadır, ağımtıl, bənövşəyi, uzununa zolaqlıdır. Tozcuğu mavidir, qutucuq 5 sm uzunluğunda, uzunsov –yumurtavari, üçtillidir [3][4][5].
Çiçəkləmə, meyvə əmələ gətirmə dövrü aprel-may aylarının birinci ongünlüyünə təsadüf edir.Mezokserofit, işıqsevəndir. Kökümsovlarla və toxumla çoxalır. Kolluqlarda, oltu yamaclarda qruplaşmalar əmələ gətirir. Düzənliklərdə və aşağı dağ qurşağında yayılmışdır.Dekorativ bitkidir [4][5][6]
Kür düzənliyi, Bozqır yaylası [4][6][7]. Sayı və tendensiyası: Mənfi antropogen təsirlər növün itmə təhlükəsini yaradır [5].
Antropogen amillər (dekorativ bitki kimi hali tərəfindən intensiv yığılması, otarılma, tapdalanma).
Yayıldığı sahələrin, təbii populyasiyalarının mühafizə olunması üçün xüsusi tədbirlər aparılmır, antropogen təsiri azaltmaq məqsədilə yayılma yerlərində yasaqlıqların təşkili, yeni yayılma yerlərinin axtarılması, toxumlarının toxum bankında saxlanılması vacibdir.

Iris alexeenkoi is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from the Caucasus mountains in Azerbaijan. It has green or greyish grass-like leaves, a short slender stem and 1–2 flowers that come in shades of purple, violet, purple-blue, or blue. It is closely related to Iris pumila. It is rarely cultivated as an ornamental plant in temperate regions.
It is a dwarf, bearded species which is closely related to Iris pumila L.[2][3][4]
It has a thick and short rhizome.[5] They are bigger than Iris pumila,[3] and fibrous.[4]
It has green,[4] or greyish leaves, which are sword-shaped, with pointed ends.[5] They are grass-like, and form tufts of plants.[4] They can grow up to between 10–25 cm (4–10 in) long,[4][6] and between 0.4 and 1 cm wide.[5] They are longer than Iris pumila.[7]
It has a slender stem, that can grow up to between 20–30 cm (8–12 in) tall.[8][9]: 184 [10]: 62 It has a very, very small pedicel, similar to Iris pumila.[2]
The stem has green, glaucous, (scarious) membranous, spathes (leaves of the flower bud).[5]
The stems hold 1,[5][7][10] or 2 terminal (top of stem) flowers,[4] blooming in spring,[6] in April.[4]
The large flowers,[3][6] come in shades of purple,[5] violet,[3][8][9]: 184 purple-blue,[2][7][8] or blue.[6][10] The flowers are larger than Iris pumila.[4][7]
It has a long, thin perianth tube, which is purple, but with a brown colour at the base. They are longer than the ovary.[5]
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'.[9]: 17 The narrow,[9]: 184 falls oblong or elongated, and reflexed, they can grow up to 4.5–5.5 cm (2–2 in) long.[5] In the centre of the petal, it has a varied coloured beard, in blue,[5] light violet,[9]: 184 white tipped with yellow,[2][4] or yellow.[8][9]: 184 [10] The standards are longer than the falls.[5][9]: 184 They are ovate or oblong shaped, they also have dark purple veining.[5]
After the iris has flowered, it produces an ovate, oblong or triangular seed capsule, that is 5 cm (2 in) long.[5]
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[9]: 18 It has a chromosome count: 2n=32.[4][8]
It is known as Alеksеy süsəni in Azerbaijan.[11]
It is commonly known as 'Alexeenko Iris' in Russia.[5]
The Latin specific epithet alexeenkoi refers to a Russian plant collector called 'Fyodor Nikitich Alexeenko' (1882–1904). Who was born in Pavlograd in Russia, and then studied at the St. Petersburg Forestry Institute. He later in 1897, set out on a 3-year expedition in the Russian Caucasus, where he made significant collections of plants including Iris alexeenkoi. He then went Central Asia in 1901, gathering some 4,000 specimens from the Pamir Mountains, Wakhan Ridge, Shugnan (Afghanistan) and Darvaz. In 1903, he collected over a thousand specimens in Iran. Then in 1904, he was killed while attempting to illegally cross the Swiss-French border at Geneva.[12]
On 4 December 1902, a specimen of Iris alexeenkoi was collected from a region closer to the village of Novoivanovka in Azerbaijan, at an altitude of 2800 ft.[13]
It was first published and described by Alexander Alfonsovich Grossheim in 'Botanicheskie Materially Gerbariya Botanicheskogo Instituta Imeni V. L. Komarova Akademii Nauk S S S R' (Bot. Mater. Gerb. Bot. Inst. Komarova Akad. Nauk S.S.S.R.) in 1950, Vol.8 on page 6.[14][15] The journal is sometimes referred to as 'Not. Syst. Herb. Inst. Bot. Acad. Sci., URSS'.[2]
It was verified by United States Department of Agriculture and the Agricultural Research Service on 4 April 2003 and then updated on 2 December 2004.[15]
It is listed in the Encyclopedia of Life.[16]
Iris alexeenkoi is a tentatively accepted name by the RHS.[17]
It is native to temperate Asia.[15]
It is found in the Caucasus mountains,[5][10]: 118 [17] (also known as the Transcaucasia region,[7][8][18]) within Azerbaijan.[14][15] Including the regions of, Ganja-Gazakh Area,[19] Baku Province,[10]: 118 and Shiraki.[3][4]
It grows on the dry[18] plains, meadows,[5] and steppes,[7] of the lower mountain region.[5]
They can be found at around an altitude of 2,800 ft (850 m) above sea level.[13]
It is a rare and threatened plant,[4] of Azerbaijan, with Iris camillae, Iris iberica, Iris pumila and Iris schelkownikowii.[19]
It is hardy to very warm climates,[3] as it does not stand cold.[4] It can be grown in a greenhouse and cold frame.[3]
It is best grown in well-drained soils, in sunny positions.[4][6]
It can be grown in garden borders and pots.[6]
It is susceptible to viruses,[4][7] and slug damage.[4]
It is extremely rare in cultivation.[3][4] It is thought that plants found in the US are mislabelled Iris alexeenkoi.[2]
A herbarium specimen can be found in the collection of Royal Botanic Garden Edinburgh.[13]
Like many other irises, most parts of the plant are poisonous (rhizome and leaves), and if mistakenly ingested can cause stomach pains and vomiting. Also, handling the plant may cause skin irritation or an allergic reaction.[20]
