Iris iberica subsp. elegantissima is a subspecies in the genus

temperate
regions, but normally needs some protection during the winter period.

Description

It is classed as an mezo-

stoloniferous rhizomes which are about 3 cm long. Underneath the rhizomes, it has very long secondary roots.[3]

It has large,[4] ribbon-like,[3] and falcate (sickle-shaped),[5][6] leaves, that can grow up to 20–30 cm (8–12 in) long,[3]

It has a slender stem or peduncle, that starts to grow in March,[3] up to 20–30 cm (8–12 in) tall.[7][8][9]

The stem holds a terminal (top of stem) flower,[3] the plant normally has 2–3 stems,[4] each with flower buds,[10] blooming in Spring,[11] between late March,[3] or April and May,[4][12] or June.[5]

The large flowers, are 10–14 cm (4–6 in) in diameter,[6][8] they have a white,[5][6][13] cream,[3] or pale yellow ground,[8][11][14] has dark,[9] veining or speckling in violet,[5] mauve,[10] purple or brown shades.[3][11] Compared to Iris iberica which can have blue veining and marking.[13]

Like other irises, it has 2 pairs of petals, 3

scallop shell shaped,[10] falls are deflexed (bending over to an almost flat position),[10][11] and up to 6–8 cm (2–3 in) long.[5] in the center of the falls, is a velvet-like,[5] dark,[14] brown to purple,[3] or black signal patch.[5] Also, in the middle of the falls, is a row of short hairs called the 'beard', which are brown to purple.[3]
Also over the falls, the iris has a deflexed style branches that almost covers the signal spot.[13] The almost vertical,[11] and larger standards,[17] are creamy,[5] or white,[6] with pale,[3] or thin violet veins.[5] They are up to 6–10 cm (2–4 in) long,[5][10] and can be described as white cotton handkerchiefs.[10]

The flowers produce pollen, which has been precisely measured, the long axis is 114 micrometres (0.0045 in) long and the short axis is 111 microns long.[18]

After the iris has flowered, it produces a seed capsule between June and July.[5][2] Then the plant dies back, losing the leaves and stems, to rest underground during the winter.[2]

Biochemistry

As most irises are

diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.[16]
: 18  It has a chromosome count: 2n=20,[3][14][19] and has an unnamed alkaloid (as of 1961), contained within its rhizome.[20]

A study in 2014, was carried out on various species of iris DNA, it found that I. iberica ssp. elegantissima had a purity value of 2.80, compared to 1.26 of Iris aucheri.[citation needed]

Taxonomy

The Latin specific epithet elegantissima refers to 'elegantissimus' meaning very elegant,[21] it is a superlative of 'elegans'.[22]

It was first discovered in Transcaucasus,

Dmitrii Ivanovich Sosnowsky in Vestn. Tiflissk. Bot. Sada Vol.11 on page 2 in 1915.[1][23] In 1972, it was then re-classified as a subspecies of Iris iberica by A. L. Takhtadzhyan and A. A. Fedorov, and published as Iris iberica subsp. elegantissima (Sosn.) Fed. & Takht. in Fl. Erevana Vol.331 in 1972.[1][24][25]

Although it is often referred to as Iris elegantissima Sosn. in Russia and Armenia.[26][27][28] but elsewhere it is referred to as a subspecies.[29][30][31]

It was verified as Iris iberica subsp. elegantissima by United States Department of Agriculture and the Agricultural Research Service on 22 February 2006, then altered on 11 December 2007.[24] It is listed in the Encyclopedia of Life,[32] and is an accepted name by the RHS.[33]

Distribution and habitat

It is

native to temperate Asia.[24]

Range

It is found in Armenia,

East Anatolia,[5]) including near Lake Van Basin,[29] Erzurum,[10] and Ararat.[34]

It was listed as found in Azerbaijan, in 2004,[35] but this either a cultivated form or mistaken form of Iris iberica, which is naturally found there.[36]

Habitat

It grows on the lower and middle mountain belts,

coniferous forests.[4][15]

They can be found at an altitude of 750–2,250 ft (230–690 m) above sea level.[5][4][10]

Conservation

It is a rare species,

Red Data Book of Armenia,[5][12][26] but not included in the Annexes of CITES and that of the Bern Convention.[5]
It is at risk due to various factors, including urbanization, land development for arable purposes (framing) and the intensive collection (of the flowers) for selling.[5]

The species grows and is monitored within

Triticum boeoticum and Triticum urartu.[26]

It is also grown in Yerevan Botanic Garden in Armenia.[37]

Cultivation

'Oncocyclus Section' Irises are in general easier to grow than 'Regalia Section' irises.[6] I. iberica subsp elegantissima is hardy to European Zone 4,[11] (meaning hardy to −5 to −10oC (23 to 14oF).[38] In the UK, it needs to be covered through the winter,

alpine house.[10][39]

The irises grow within fertile,[39] highly drained soil,[4][39] in full sun,[7] but needs protection from rain in the late summer and winter.[4][30][39] In the US, the rhizomes are susceptible to being dug up by squirrels.[30]

Propagation

Irises can generally be propagated by

stratification, (the cold treatment), which can be carried out indoors or outdoors. Seedlings are generally potted on (or transplanted) when they have 3 leaves.[41]
Oncoyclus irises dislike division, but it should only be carried out when the plant is overcrowded. Although hand pollination and germinating seedlings gives better results.[42]

Toxicity

Armenia produced stamps for Iris elegantissima and Iris lycotis (subspecies of Iris iberica)

Like many other irises, most parts of the plant are poisonous (rhizome and leaves), if mistakenly ingested can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.[43]

Culture

On 19 December 1997, as part of Flora and Fauna of Armenia (III issue) in the 'Irises' series, 2 stamps had images of the irises,[12] (See images on the right), also on 12 August 1993, a commemorative stamp was issued in Azerbaijan, from the Flowers series, Iris elegantissima.[44]
