Iris bucharica Foster, Gard. Chron., ser. 3, 31: 385 (1902).
A Guide to Species Irises, their Identification and Cultivation, The Species Group of The British Iris Society, 1997, Cambridge;
-J. G. Baker in the Curtis's Botanical Magazine, Tab. 7111. April 1st., 1890 described a specimen of "Iris orchioides" which later is shown to be not the true Iris orchioides of Carriere but a yellow form of _Iris bucharica_
Later Hemsley not yet aware of this error gives the following description of the new Iris bucharica in Curtis's Botanical Magazine table 7914, in September of 1903: "This pretty Iris is one of a series of four which Sir Michael Foster, one of the first authorities on the genus, says might well be regarded as varieties of one species, 68(B.M. t. 7111). But he argues that as they present ******* distinctive, which, from a gardener's standpoint, constitute species, they may as well be accepted as such. This may be a convenient coarse so long as there are only the four to deal with; but, judging from very scanty material, there is considerable individual variation, and I am not quite certain that our plant is exactly his I. bucharica. He himself says that one of the four of this series, the one known as I. orchioides caerulea, was referred by Regel to I. caucasica, Hoffm., and I find that Regel ( Gartenflora, t. 800) figures a plant exceedingly like ours, especially in the three-lobed deflexed inner petals or standards, as I. caucasica.</br.The plant here figured was purchased from Messrs. Van Tubergen, Dutch Nurserymen, and it flowered in the Alpine House at Kew in March of the present year. Sir Michael Foster obtained his from the same source, as well as the closely allied, though very differently colored I. warleyensis, described and figured in the same place, and which will shortly be figured in this Magazine. He describes the standards of I. bucharica in the following words: "small, pure white, extended horizontally, with a canaliculate claw expanding into a broader, flat, distinctly mucronate blade." On the other hand, the figure in the Journal of Horticulture" cited above has distinctly lobed standards.*Descr.* -Closely allied to I. orchioides and I. caucasica, and having a nearly globose bulb. Stem erect, one to two feet high; internodes distinct. Leaves seven to eleven, lanceolate, acuminate, acute, lower ones nine to twelve inches long, shorter upwards, curved, shining. Spathes solitary in the axils of the leaves, one-flowered, scarcely acute, not inflated. Flowers shortly peduncled, yellow and white, about two and a half inches across. Perianth-tube elongated. Petals all having long claws; the three outer (falls) with an oblong, rounded, pendulous, crested blade; the three inner (standards) much smaller, protruding between the outer, pendulous, three-lobed; lateral lobes rounded, central one acuminate."
Dykes provided an image of a bucharica seed in his Genus Iris but recent images do not seem to be a close match??

Dykes, The Genus Iris, tab. 41, 204. 1913, (note Dkes and others for many years confused a yellow bucharica with the true species orhioides which they never had seen)Description. Rootstock , a bulb, similar to that of l. orchioides, but apt to be more globose. Leaves , 8-12 in. long by 2-2½ in. broad, bright green, deeply channelled towards the upper end, the upper surface glossy and the under glaucous, with a narrow white horny margm, bearing a number of inconspicuous setae. Stem , 12-18 inches high, bearing 5-7 flowers set in the axils of the leaves. Spathe valves , 3 in. long, projecting ¾ in. above the standards, of a paler green than in orchioides, slightly scarious at the tip and edge. The outer valve when unrolled is very wide, as much as 1½ m. across. Pedicel , practically none. Ovary , nearly ¾ in. rounded, trigonal. Tube , 1½-2 in. Falls , over 2 in. long, blade more than 1 in. broad. The pure white strap-shaped haft is separated by a slight constriction from the obovate or even orbicular blade of a bright golden colour, emarginated and bearing a large wavy golden crest, which is continued along the haft as an inconspicuous median ridge, faintly dotted with dark green. In some specimens dark purplish veins flank the crest as in orchioides, but in others these are entirely absent. Standards , small, pure white, depressed below the horizontal ; the short canaliculate haft expands into a broadly lanceolate, distinctly mucronate blade. Styles , pure white, very large and conspicuous, standing up well above the falls. Crests , large, and reflexed to an upright position, pure white, quadrate or obscurely deltoid. Stigma , conspicuous, white, semicircular in outline, but much narrower than the style. Filaments , colourless. Anthers , creamy white. Pollen , spherical, with hexagonal bosses. Capsule , cylindrical, 2½ in. long, with six sides arranged in three pair{-- Walls thin and bulging, showing the outline of the seeds within. Seeds , numerous, deep buff or light reddish brown, irregularly cubical. See Plate XLVIII, Fig. 6.
