Iris narbutii

From Kazakhstan Encyclopedia

Template:Italic titleTemplate:Taxobox Iris narbutii is a species in the genus Iris, it is also in the subgenus of Scorpiris. It is a bulbous perennial. It is sometimes misspelt as 'Iris narbuti'.[1][2]

It was first published as 'Juno Narbutii' by Olga Fedtschenko in 'Izvestiya Imperatorskago Obscestva Ljubitelej Estestvoznanija, Antropologii i Etnografii, Sostojascago pri (Imperatorskom) Moskovskom Universitete' in 1902.[3] It was later published as 'Iris Narbutii' by Boris Fedtschenko in Bull. Jard. Bot. St. Petersb. Vol.V page157 in 1905.[4]

Iris narbutii is now an accepted name by the RHS.[5]

It is listed in 1995 in 'Vascular plants of Russia and adjacent states (the former USSR)' by Czerepanov, S. K.[6]

It may have been named after 'Narbuta Beg'(1774-1798), a grandson of 'Abd al-Karim' (Khanate of Kokand) of the Fergana Valley, Central Asia, where the iris was found.[7]

It can be seen growing in the 'Le Grand Clos Botanique Garden' in Bourgueil, France.[8]

It can be cultivated in pots,[9] or in well drained soils in sunshine (like other Juno irises).[10]


Iris narbutii has a brown bulb with papery tunic,[9] the bulb is approx. Template:Convert in diameter.[11] It has thickened roots,[4] which look similar to fat short pointed tubers.[12]

One of the shorter Juno irises, similar to Iris Lepthoriza,[9] only growing to a height of Template:Cvt.[4][10][13][14]

It blooms in early-mid spring,[11] flowering between January to April depending on the weather conditions.[4][9][10] It has 1 or 2 scentless flowers per bulb stem.[4][11][13]

The flowers come in a range of shades between greenish-yellow to pale violet.[9][10][13] The green-purple perianth tube is about Template:Cvt long.[4][11] It has standards (Template:Cvt) that hang downwards.[10][14][15] It has falls that start upright, but then the blade bends downwards, with a dark violet blotch at the tip. They have a raised white crest surrounded by a yellow zone/area.[9][10][13][14][15] The yellow zone can sometimes have a dark purple ring around it.[11]

It has whitish pollen.[4]

The thin, channelled dark green leaves emerge before the flowers, they are 5–25 mm wide (close to the base of the plant).[4][10][11] They gradually narrow to an apex (falcate-like, lanceolate)[9] and have a very visible white edging/margin.[4]


Iris narbutii is from Central Asia.[13][15] Originally found on the slopes of Syr-Darya river valley.[4][14]

It is found on the rocky, gravelly slopes of the mountains of western Tien Shan and southern Pamir Mountains.[11] Also seen near to Samarkand and Tashkent.[4]

Olga Fedtschenko had speculated that the plants from west Tien Shan, could be a separate species, due to their paler colour.[4]

In Chulbair Mountains, Uzbekistan, it is a threatened species and close to extinction.[9]

Known hybrids

  • Iris narbutii 'Kara Kaga'[15]

In Russia, Vvedenskii had noted several natural hybrids including; J. narbutii x J maracandica (near Jizzak, Uzbekistan), J. narbutii x J. Orchioides and J. narbutii x J. subdecolorata (near Darbaza, Kazakhstan).[11]
