Template:Italic titleTemplate:Taxobox Iris loczyi is a beardless iris in the genus Iris, in the subgenus Limniris and in the Tenuifoliae series of the species. It is a rhizomatous herbaceous perennial, from a wide area of Asia, including Afghanistan, Iran,(the mountainous parts of Pakistan), Kazakhstan, Tajikistan, Mongolia, Tibet and China. It has long thin grey green leaves, long stems and 1 flower in pale violet, blue violet, lavender or light blue.
It has a slender, fibrous, knobbly or gnarled, brown-black rhizome. It forms hard thick, tussocks or clumps of plants. On top of the rhizome are maroon-brown, fibrous (or straw-like), remnants (of last seasons leaves), as sheaths (of the new leaves).
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 falls are oblanceolate (top wider than the bottom) or slightly obovate, Template:Convert long and 1–2 cm wide. They are veined with a darker shade and have a white or cream (occasionally yellow), signal area (central area). The single coloured standards are also oblanceolate, erect, Template:Convert long and 7-8mm wide.
After the iris has flowered, it produces a reddish-brown ovoid to cylindric seed capsule, Template:Convert long and 2 cm wide between June and September. The capsule has 6 veins, and a short beak-like appendage on the top.
In 2008, a study was carried out on the anatomical structure of the leaf and drought resistance of 4 different species of Iris (Iris songarica, Iris potaninii, Iris loczyi and Iris lactea) from Qinghai, China. It showed that all the species were strongly adaptable to drought conditions.
Distribution and habitat
It is found in the western Asia countries of Afghanistan and Iran. Including; the Caucasus regions of Pamir Mountains, Tien Shan (within Kometydavan Ravine and Se-chai River) and Baluchistan (the mountainous parts of Pakistan and Iran).
It is listed with Iris bloudowii, Iris psammocola, Iris ruthenica, Iris sibirica, Iris tenuifolia and Iris tigridia as being found in the Altai-Sayan region (where Russia, China, Mongolia and Kazakhstan come together).
It is found growing on high mountain grasslands, (or steppes) and sunny hillsides. It is widespread on the mountains of Central Asia. At altitudes of between Template:Convert above sea level.
It was mentioned in (under the name Iris tianschanica) in Czerepano's 'Vascular Plants of Russia and Adjacent States (the Former USSR)' in 1995.
It is an endangered species in Uglovsky District of Russia. Only 20 individuals were counted. Although the plants were not eaten by cattle, destruction of the habitat is the major factor in limiting its range.
In China, it is forbidden to export plants or seeds. The reason is not known, but may be due to the medicinal usage of the plants.
