This is a new bulbous Iris, allied to persica, caucasica, 
orchivides and palestina, which seems likely to be very 
popular. It was first found not many years ago by the 
Russian botanists on the mountains of Turkestan and 
Bokhara, at an elevation of from six thousand to nine 
thousand feet above sea-level, and has been widely dis- 
tributed by Dr. Regel. Professor Foster says that ‘it is 
quite hardy in England, and more variable in the colouring 
of the flower than any other species of the genus. Full 
details of the range of variation will be found in his two 
papers in the “ Gardener’s Chronicle,’ above cited. Our 
drawing was made partly from plants that flowered at Kew 
last February, and partly from material furnished by Pro- 
fessor Foster. ; ‘
