Iris setina is a species in the genus Iris, it is also in the subgenus of Iris. It is a rhizomatous perennial, from a small region in Italy.It has glaucous sword-like leaves, slender branched stem, and one or two violet toned flowers. It is not yet cultivated as an ornamental plant in temperate regions.
It is similar in form to Iris germanica.
It has evergreen, glaucous and smooth leaves. Most are ensiform (sword-like) but a few were falcate (sickle-shaped). They can grow up to 40 cm (16 in) long and between 3 cm wide. Although, the leaves at the stem base are smaller.
It has a slender stem or peduncle, that can grow up to between 11–50 cm (4–20 in) tall. They normally have 2 branches, the lowest branch is about 11–14 cm (4–6 in) long. The branches have one small, narrow stem leaf, around 7–10 cm (3–4 in) long.
The upper branch has a slightly inflated spathes (leaves of the flower bud), which are slightly violet stained or marked.
The stems (and branches) hold between 1 - 2 terminal flowers, blooming between February and early March.
The flowers come in shades of violet, or violet-purple. 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'. Some flowers are bi-toned, with the falls darker than standards.
After the iris has flowered, it produces a seed capsule, which has not yet been described.
As most irises are diploid, having two sets of chromosomes, this can be used to identify hybrids and classification of groupings.
In 1993, Colasante & Saur (in Linzer biol. Beitr. Vol.25, Issue2 on page 1189) stated that Iris setina could be regarded as an allopolyploid and theorise that it may have derived from other bearded dwarf species such as Iris pseudopumila Tineo and Iris pallida Lam.
