The Japanese specimens in the Gray Herbarium, collected in different parts of the 

 country (Nagasaki, Yokohama, Hakodate, Sapporo), are all referable to A. fulvus, Sm. 

 They are all glaucous, and have inflated sheaths and yellow or orange-yellow anthers. 

 The plant has been found in Saghalin, northern China, Hongkong, Himalaya, and Altai 

 to Europe. Some of the specimens from northwest America can scarcely be distinguished 

 from our plant.

Our plant has flat leaves and greenish flowers, which are sometimes slightly tinged 

 with a purplish color. The panicle is branched from about the middle, and is more or less 

 scabrous, as also the keel of the glumes. The plant is just about intermediate in its gen- 

 eral characters between A. ])erennans and scabra. A specimen from Saghalin, collected 

 by F. Schmidt, coincides very closely with ours; so is also one named A. Michauxii, 

 var. clavata, from Kamtschatka. The present form seems to occur also in northwestern 

 America to Colorado (J. Wolf) and to the lake region.
