Iris taochia is a plant species in the genus Iris, it is also in the subgenus Iris. It is a rhizomatous perennial, from the Caucasus mountains and Turkey. It forms dense clumps, with grey-green leaves, simple stems of similar height, with 1–3 branches, a flowers in various shades from white, yellow to purple.

It is similar in form to a dwarf form of an Iris aphylla. It has partially exposed rhizomes, that branches to form a dense clump. It has falcate (sickle-shaped), grey-green leaves, deciduous, simple, sheathing leaves. They can grow up to 30 cm (12 in) long, and between 1.5 and 2.5 cm wide. The leaves are a similar height to the flowering stems, but broader than those of Iris schachtii. It has a slender stem or peduncle that can grow up to between 15–35 cm (6–14 in) tall, with 1–3 branches, (or pedicels). The stem (and branches) have inflated, green, spathes (or leaves of the flower bud). The stems (and the branches) hold 2 and rarely 5 flowers in spring, between April, or between May and June. The large flowers are 5–7 cm (2–3 in) in diameter, and come in shades from white, yellow to purple, including pale yellow, gold, brownish-red, reddish purple, blue, and violet. 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'. In the middle of the falls, there is a row of short hairs called the 'beard', which are yellow, or white, tipped with yellow, a few forms can have a purple beard. After the iris has flowered, it produces a seed capsule which has not been described. Genetics As most irises, this iris is diploid, having two sets of chromosomes. This can be used to identify hybrids and classification of groupings. In 1989, a karyological study was carried out on 4 iris species in Turkey; including Iris junonia Schott et Kotschy ex Schott, Iris purpureobractea B. Matthew and T. Baytop, Iris taochia Woronow ex Grossh., and Iris schachtii. It found the chromosome counts of the various iris specie. Iris taochia had a count of 2n=24. It was also re-counted in 1990, by Şenel, G. & S. Özyurt. in Erzurum çevresinde yayilis|7 gösteren Iridaceae familyasina ait bazi goefitler üzerinde karyolojik incelemeler. X.
