t Mr. Dall collected, in the spring of 18G7, a large number of willows, but owing to his 

 short stay in a given locality was of course unable to match the sexes or to obtain the 

 leaves. For want of material I am therefore compelled to pass them by. 



* For want of material I am obliged to accept the determination of Ledebour's Flora Ros- 

 sica in regard to this order almost "in toto." I have, however, kept up the distinction 

 between Abies and Pinus for manifest reasons.
