My dear Dr. Sandberg: — 



I have been looking over your willows this 

 morning and will proceed to give you my first impressions as to 

 names &c- an informal 11 talky talky" report. By and by when I 

 come to mount the specimens I shall want to give a few of them 

 a more careful examination with the aid of those capital helpers 

 a cup of hot water and low power microscope.

12a I should without much hesitancy refer the male A to S. petiola- 

 ris y. gracilis but the pistillate have a doubtful look, as if 

 they showed a cross with S. cor dat a. Without the leaves it is im- 

 possible to feel perfectly sure, so I would advise you, for the 

 present at least, to withhold these from distribution.
