Description

I. schelkownikowii creates small clumps of plants, withleaves that stay intact until the end of the summer.[3]

It has slightly fragrant,[2] flowers which are 8–10 cm (3–4 in) cm across.[4]

Like other irises, it has two pairs of petals: three large sepals (outer petals), known as the 'falls', and three inner, smaller petals (or tepals), known as the 'standards'.[5] The standards are bluish,[3] or grey-purple violet.[4] They are darker than the falls and have dark brown veining.[2] The falls have a reddish/purple blotch,[3] or purple signal patch.[2] Behind the signal patch on the falls is a row of short, dense bristles or hairs called the 'beard' which is yellow.[3][2]

Biochemistry

As most irises are diploid, having two sets of chromosomes. This can be used to identify hybrids and classification of groupings.[5] It has a chromosome count of 2n=20.[2]

Taxonomy

The Latin specific epithet schelkownikowii refers to a botanist called Alexandr Bebutovicz Schelkownikow (or Schelk.) (1870-1933).[6] He has co-collector of plant specimens with Georg Jurij Nikolaewitch Woronow.[7]

It was originally published as Iris schelkownikowii by A.V. Fomin and G.J.N. Woronow in Opred. Rast. Kavk. Vol.1 on page 299 in 1907.[1][8] It was then re-published by Fomin in Opred. Rast. Kavk. Kryma (Opredelitel' Rastenjj Kavkaza i Kryma (vypusk 5)) on page 299 in 1909 as Iris schelkownicowii.[9][10]

It has also been mis-spelled with a single i at the end as schelkownikowi.[11] Most of these are early mentions pre 1970s.[12]

Both forms of the name (ending in ..cowii or ..kowii) still exist today but it has been verified as Iris schelkownikowii by United States Department of Agriculture and the Agricultural Research Service on 27 February 2002 and then updated on 7 July 2016.[10]

Distribution and habitat

It is native to temperate Asia.[10]

Range

It is found in the Southern and eastern Transcaucasus regions,[4] in Azerbaijan.[2]

Habitat

It prefers to grow in a hot and dry climate,[3] such as steppes.

Cultivation

The clumps of I. schelkownii should be divided every second year, so that it will continue to make more flowers the next year.[3]

Toxicity

Like many other irises, most parts of the plant are poisonous (including rhizome and leaves), if mistakenly ingested, it can cause stomach pains and vomiting. Also handling the plant may cause a skin irritation or an allergic reaction.[13]
