 Iris obtusifolia 1900, Baker

Iris obtusifolia ( John Gilbert Baker, 1900)

Curtis's Botanical Magazine, table 7701. 1900; gives the following by Baker; "This new Iris is nearly allied to I. lutescens. Lam. (Bot. Mag. t. 2861), and I. Statellae, Todaro (Bot. Mag. t. 6894), from both of which it differs by its laxly arranged obtuse leaves, very ventricose spathe-valves, and by having a sessile lateral cluster of flowers in addition to the end one. It was discovered 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." He sent it in 1897 to the Royal Gardens, Kew, in a living state, and our drawing was made from a plant that flowered in the bulb-house in April, 1899.

Description — Rootstoclc robust, shortly creeping. Leaves six, distichous, mostly basal, pale green, ligulate, obtuse, the largest six or eight inches long at the flowering season, by an inch broad. Stem a foot long, bearing one terminal and one sessile lateral cluster of flowers. Spathe-valves oblong-navicular, very ventricose, two or three inches long, pale green at the flowering season ; pedicels very short. Perianth sulphur-yellow ; tube very short ; outer segments of the limb obovate-cuneate, two inches by an inch broad above tbe middle, reflexing from the middle, furnished with an orange-yellow beard more than halfway up; inner segments erect, as long as the outer, cordate-orbicular, with a short, narrow claw. Style-branches pale yellow, an inch long ; crests deltoid, irregularly toothed on the outer edge. — J. G. Baker.
