The falls are obovate, and long, and 1–1.5 cm wide. It has in the centre of the petal, is a white patch, and a beard, with blue-white, or white hairs, tipped with yellow, or yellow hairs. The erect, or tilting outwards, standards are oblanceolate, and long and 0.4–0.7 cm wide. They are darker shade than the falls. It has a 5 mm long pedicel, and 2 cm long perianth tube, that widens out at the top. It has 2.3–2.5 cm long styles, that have triangular crests. It has blue pollen, and a long, green ovary, that is up to 1.2 cm long. It has 1.5 cm long stamens. After the iris has flowered, between June and July, or up to August, it produces an ovoid, or fusiform (spindle shaped), seed capsule. That is between long, and 1.5–2 cm in diameter. It has a beak like top, attached to the remains of the perianth tube. Inside the capsule are roundish, or pear shaped (pyriform), seeds. They have a creamy, or yellowish white aril (appendage). In 2003, a study was carried out on the chromosome sequencing of various Irises from the Siberian region of central Asia. They sequenced the rbcL gene from some Siberian Iris species belonging to different subgenera including, "Iris halophila", "Iris ludwigii", "Iris uniflora", "Iris pseudacorus" and "Iris laevigata". Their results supported Brian Mathew’s classification from 1989. That "Iris bloudowii", "Iris humilis", "Iris ivanovae", "Iris tigridia", and "Iris glaucescens" form a cluster. In 2011, a chromosome and karyotype analysis study was carried out on the rhizomes of "Iris tigridia". It found that the chromosome number of Iris tigridia was 2n=18. As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings. It has been counted several times. Including by Doronkin in 1984. It has been counted as 2n=18, 20, 22, 24, 28, 32, 34, 38, and 40.
