## Description

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

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

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'. The standards are bluish, or grey-purple violet. They are darker than the falls and have dark brown veining. The falls have a reddish/purple blotch, or purple signal patch. Behind the signal patch on the falls is a row of short, dense bristles or hairs called the 'beard' which is yellow.

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

## Taxonomy

It was originally described as Iris acutiloba var. schelkownicowii by A.V. Fomin in 1904. Fomin raised it to a full species in 1909. The Latin specific epithet schelkownikowii refers to a botanist called Alexandr Bebutovicz Schelkownikow (or Schelk.) (1870-1933). He was a co-collector of plant specimens with Georg Jurij Nikolaewitch Woronow.

It has also been misspelled with a single i at the end as schelkownikowi. Most of these are early mentions pre 1970s.

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.
