Lindley in , illustrated in color; offers this original description: (translated from Latin)-"Foliage wide, rigid, erect, scape with short branches, oval bracts, leafy and opposite each other, with a membranous tip, and tightly imbricated, Sepals bearded and rounded at tip, petals obovate, shallowly notched. Perianth tube short." Lindley makes the further comments "This is a very showy perennial, which most probably will prove quite hardy in the open border, if planted in a rich sandy loam and warm situation. It is increased by dividing the old plants any time from October to March, and flowers about the end of May. Our specimens were forwarded in May, 1844, from Spofforth by the Hon. And Very Rev. the Dean of Mancester. With the history of the plant we are unacquainted. It is probable that it is a mere variety of I. squalens; from which it differs in its pure lemon-coloured flowers, and in the imbricated short blunt convex bracts which invest their base."

"Bearded Irises Tried at Wisley"-Journal of The Royal Horticultural Society p,127 151.;
Bull. A.I.S. 57: 96., 97. Apr. 1935, Iris imbricata Lind!. Under the names of Iris sulphurea and Iris Talischii this plant has been received from the Triflis Botanic Garden and although there is some difference in the coloring of the several seedlings in each lot, there is hardly. enough to warrant even garden separation, although the seedlings in the lot labelled I. sulphurea are a very decent pale yellow color and there is little of the reddish markings on the inside of the hafts. Dykes (The Genus Iris, p. 180) mentions the fact that under some conditions the falls are often marred by "dull, diffuse, irregular purple veins and blotches." Our plants have shown no blotches but some faint veins particularly in the area about the beard. There was a marked difference in the carriage of the falls, most of which would not please the fancier of bearded iris. Dykes (ibid.) notes that this iris is difficult to distinguish from the yellow-flowered form of Iris Albertii, but of the latter plant we have no comparative material. The illustration of this species in Botanical Register XXXI, pI.35 (1845) is well drawn, but has more green coloring than any specimen seen here. The text is less valuable. The figure in Curtis Botanical Magazine Tab. No. 1 (1900) is less characteristic and the text valuable chiefly for the note concerning the introduction by the "late Lieutenant-Colonel Henry Lake Wells in the year 1895, in the province of Mazanderan, on the south of the Caspian Sea. Colonel Wells describes this province as a "lovely country, full of beautiful flowers, and amongst others I found a yellow Iris, growing beside the streams at an elevation of about seven thousand feet above sea-leveL" In a time when all the breeders of tall bearded iris are striving for tall yellows of the best types, it is hardly to be expected that anyone would be keen about this plant that fails so far in theirfloristic standards. ;
