This new Iris is nearly allied to I. lutescens, Lam. (Bot. 
Mag. t. 2861), and J. Statellx, 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 Mazan- 
deran, 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. 
Descr.—Rootstock 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
