This very distinct Iris was discovered in Turkestan 

 about 1870,' by the collector whose name it bears. It was 

 imported into England from St. Petersburg by Mr. 

 William Bull in 1874, but is still very little spread in 

 English collections. We received the fruit in 1876, grown 

 by Max Leichtlin at Baden-Baden. The type is most like 

 I. iberica in the colouring of the flower, but in the habit 

 of growth and character of the beard it approximates to 

 I. biflora and lutescens. Dr. Foster's concolorous purple 

 variety is now published for the first time, and of course, 

 for garden purposes, is very distinct from the type. The 

 species was flowered both at Cambridge and Kew in the 

 month of May this present year. 



Desuk. Rhizome shortly creeping. Basal leaves ensiform, 

 glaucous, a foot long at the flowering time, an inch broad. 

 Peduncle one-headed, about a foot long, bearing a single 

 reduced leaf below the middle. Head usually two- 

 flowered ; outer spathe- valves very large, oblong-lanceo- 

 late, four or five inches long, green at the flowering time, 

 pedicels short. Ovary linear-oblong, strongly angled, above
