J. D. Hooker in Curtis’s Botanical Magazine, vol. 128 (ser. 3, vol. 58): t. 7867 (1902) (M. Smith) provides the following description;


"In point of size of flowers, I. Gatesii is, as far as is at present known, the monarch of the Irises. It belongs to a section (Oncocyclus) of the genus conspicuous in this respect, of which five have been figured in this magazine, namely, I. susiana, Linn. T. 91; I. lortetii, Barb. T. 7251; I. sari, Schott. Var. lurida, Boiss. T. 6960; I. iberica, Hoffm. T. 5817, and I. paradoxa, Stev. T. 7081. All of the section are Oriental, ranging from Asia Minor and Syria to Persia.

I. Gatesii was introduced into cultivation by Mr. Max Leichtlin, who obtained it from Mr. Sintenis, its discoverer in the mountains of Kurdistan, in Mesopotamia, near the town of Mardin, about sixty miles south of Diarbekir. It is named by Sir Michael Foster after his friend, the Rev. F.S.Gates, of the American Mission at that town. Mardin is described as situated on a lofty limestone hill, overlooking a large fertile plain, and is distinguished for the salubrity of its climate, and for containing substantially built Chaldean, Syrian, Catholic, Armenian, and Jacobite churches. It is not in Armenia (the hitherto reputed habitat of I. Gatesii) which lies to the northward of it.

Plants of I. Gatesii were obtained in 1901 by the Royal Gardens, Kew, from Messrs. Wulle of Naples; they flowered in an open border near a south wall in June,1902. The color of the flowers is difficult of description and probably variable.

Descr.-Rootstock very stout, short, creeping. Stems two to three feet high, stout, one-flowered. Leaves four to five, radical, a foot to a foot and a half long, by one half to two-thrds of an inch broad, linear, acuminate, nearely flat, pale, glaucous-green, nerves faint. Spathes four to five inches long, pale green. Flower shortly pedicelled, five to seven inches broad. Perianth-tube short; outer segments orbicular, recurved, three inches broad, very pale rose-lilac suffused with yellow towards the disk, covered with innumerable close-set darker veins, and sprinkled with minute purplish, spots, that are larger towards the base of the disk, which is furnished with long, erect, purplish-brown hairs; inner segments longer and more spathulate than the outer, erect and incurved, with recurved margins, similarly striate and speckled, but of a bluer color, and with three stout purple ribs from the base to beyond the middle of the disk. Style nearly two inches broad, bipartite, segments divaricate, quadrate, closely striate, with the perianth-segments acutely toothed. Capsule described as five inches long."
