All these species except the last (which may be expected) have already been 
detected in British or Russian America. G. festucaceum abounds on the Saskatch- 
awan, and is likely to occur further South. This species, and especially G. melicoides, 
of which specimens are general desiderata, arc particularly commended to the at- 
tention of Canadian botanists.
