Iris notha is a species in the genus Iris, it is also in the subgenus Limniris and series Spuriae. It is a rhizomatous perennial with deep blue or violet flowers from the Caucasus region. It is cultivated as an ornamental plant in temperate regions. It was once Iris spuria subsp. notha, and can often be found under that name. It has the common name of fake iris or mimic iris in Russia.
It has a stout, thick rhizome. That is between 8–20 mm thick. The roots are sometimes described as adventitious (in an unusual place).
It has linear, smooth, acuminate (tapering to a long point) 65–95 cm (26–37 in) long and 6-18mm wide leaves. The leaves can be as long or longer than the peduncle.
It has un-branched erect, stem, growing up to 30–90 cm (12–35 in) tall.
It has dark green, linear, lanceolate, acuminate, spathes (leaves of the flower bud).
It has unequal pedicels (stem of a single flower).
The stems hold 3-5 terminal (top of stem) flowers, between May and July.
It has un-fragranced, flowers that are up to 15 cm (6 in) in diameter, that are violet-blue and bright blue.
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'. The falls are deflexed, elliptic or ovate and narrowed at the claw (section near the stem). It has a yellow central stripe (or blaze). The standards are erect, oblong and narrowed at the stem.
It has a 20mm long perianth tube.
It has slightly recurved, style branches, that are in the same shades of colour as the petals.
After the iris has flowered, it produces a seed capsule in August. It is 6 angled, has a beak-like appendage, and woolly-ribbed.
Inside the capsule, are light brown, rugose (wrinkled), semi-circular and flattened seeds.
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: 2n=38. It has been counted several times, 38 in 1969 by O.I. Zakharyeva and L.M. Makushenko, 44 in 1970 by AK Sharma and 42 in 1978 by V Karihaloo.
