features
The iris is a perennial, herbaceous plant that reaches heights of 12 to 40 centimeters. The basic axis is quite thick. The stem is erect, branched upwards and quite floriferous. The leaves are broad to linear, sword-shaped, curved sickle-shaped, 12 to 35 millimeters wide and about as long as the flower stem. They die prematurely in autumn. The bracts are herbaceous, green at the time of flowering, the uppermost partly purple and puffed up strongly. The flowers are almost sessile and sessile. The perigone tube is about twice as long as the ovary . The perigone lobes are oblong, obverse-shaped, about the same length and rounded or edged at the tip. The outer ones are yellowish white, 4 to 6 centimeters long, delicate and criss-crossed by numerous vivid brownish or dark purple veins. They gradually narrow towards the bottom. The sections of the upper lip of the style branches are quite wide and more or less strongly serrated. The capsule is rolled, pointed and 4 to 6 inches long. The seeds are spherical, egg-shaped and about 4 millimeters long. Your shell is curled up.
The flowering time is in May and June.
The number of chromosomes is 2n = 24.
Occurrence
The natural range includes eastern Central Europe, Hungary, Croatia, Transylvania, the northern Balkans and southern Russia. The species rarely grows in forests, on stony, bushy slopes and other stony, rocky locations. It occurs in societies of the Geranion sanguinei association or the order Quercetalia pubescentis. In Central Europe it is occasionally wild.
In Austria the species occurs naturally especially in the Pannonian area (Burgenland, Vienna, Lower Austria), as well as in Carinthia, and grows here in light, dry and warm forests, especially downy oak forests, in seams and semi-arid grasslands.
