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,

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

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.
