Dykes in The Genus Iris, 1913 notes; "I. demawendica was the name given to an Oncocyclus Iris discovered in 1902 by Bornmueiller on Mt Elburs in Northern Persia (K) (BM) (V) (B). No description has been published and the dried specimens do not afford full details. It is a dwarf plant of the usual Oncocyclus character, with narrow, almost linear leaves that are only very slightly falcate, about 6 to 8 inches long. The stem of some six inches in length bears a reduced leaf and a single flower. The spathes are narrow, pointed, 2-2½ in. long, and the tube and ovary are approximately equal in length, about ¾ in. long. The falls have a dark diffuse beard and are apparently closely veined and dotted and of a deep violet-purple colour. The standards are paler and it is not impossible that the plant is merely a form of I. iberica.
Bornmueller ex K. Rechinger in Ann. Naturhist. Mus. Wien lvii. 68 (1950).
Mathew and Wendelbo reduced this to a subspecies of I. barnumae in Flora Iranica [Rechinger] 112: 35. 1975
