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'.
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. It was later published as 'Iris Narbutii' by Boris Fedtschenko in Bull. Jard. Bot. St. Petersb. Vol.V page157 in 1905.
It is listed in 1995 in 'Vascular plants of Russia and adjacent states (the former USSR)' by Czerepanov, S. K.
The flowers come in a range of shades between greenish-yellow to pale violet. The green-purple perianth tube is about Template:Cvt long. It has standards (Template:Cvt) that hang downwards. 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. The yellow zone can sometimes have a dark purple ring around it.
It has whitish pollen.
The thin, channelled dark green leaves emerge before the flowers, they are 5–25 mm wide (close to the base of the plant). They gradually narrow to an apex (falcate-like, lanceolate) and have a very visible white edging/margin.
Olga Fedtschenko had speculated that the plants from west Tien Shan, could be a separate species, due to their paler colour.
