 specimens collected by R. S. Williams, White River, Alaska, August 17, 1899, which 

 we have not seen . 



Glyceria nervata Willd. is reported from Lawson's Bay by Duranda but the 

 specimen is doubtless Panicularia borealis Nash.

 is reported from Sitka, & but the specimens cited are Panicularia pauciflora.
