 in beino- more glabrous: as in it, the summit of the larger pZ/^me 



is midway between its base and the summit of the third ^ore^ on 

 the same side. Dr. Parnell remarks that when the outer glumella 

 is opened out, Its upper margins form an angle at the point, giving 

 it a lanceolate or acuminate form, instead of being nearly rounded 

 as in B. mollis. Dr. Schultz proposes to unite B. racemosus L , B. 

 commutatus Schr., and B. secaltnus, under the name of B. miitahilis : 

 liifrli I the two former have the sheaths, especially the lower ones, hairy: 



mn * ir^ ^be last they are glabrous. B. mollis he distinguishes by being 



n-lutiip more- densely pubescent, and by having the sheaths and leaves dis-
