Iris spuria subsp. demetrii is a species of the genus Iris, part of a subgenus series known as Iris subg. Limniris and in the series Iris ser. Spuriae. It is a subspecies of Iris spuria, a rhizomatous perennial plant, from the Caucasus region, with blue-violet flowers. It is commonly known as Dimitry iris in Russia. It is cultivated as an ornamental plant in temperate regions.
The iris is very similar in form to Iris notha, another spuria Iris from the Caucasus region. Both dislike wet soils.
It has a rhizome which has not been generally described.
It has stiff, dark green leaves that can grow up to between 60–90 cm (24–35 in) long. They are narrower than Iris spuria subsp. carthaliniae, (10–18 mm wide).
It has a stiff stem, that can grow up to between 60–90 cm (24–35 in) long.
It has dark green, compact, slightly inflated, spathes (leaves of the flower bud).
The stems hold between 2-5 terminal (top of stem) flowers, in late spring.
The flowers come in shades of blue, from dark blue, to blue-violet.
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 narrow falls have blade that is the shorter than the claw (section of petal closest to the stem). The petals are veined with darker colours or white.
The capsules and seeds produced by the plant after flowering, have not been generally described.
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 was counted as 2n=38, by O.I. Zakharyeva and L.M. Makushenko in 1969.
