316 Pi'of- Don's Descriptions of the Indian Species o/Iris. 



these specimens, as well as of many others sent by Pallas, and which had 

 reached the great Swedish Naturalist towards the close of his earthly career, 

 we find no mention in any of his works ; and it appears from the papers on 

 which they are pasted, that even the charge of placing them into the Herba- 

 rium had been committed to his son. 



The chief points of difference between this species and biglumis are its 

 lengthened peduncles and narrower sepals : for in other respects they are so 

 much alike, that, without a very careful examination, the specimens might 

 readily be confounded. 



My knowledge of the colour of the flowers of this and the preceding species 

 is derived from a series of very beautiful drawings in the possession of Dr. 

 Royle.
