POPULUS MATERIAL WANTED 



The planted poplars are so little understood that I 

 am making an effort to assemble herbarium material 

 from all parts of the country. I want pressed specimens 

 of catkins and mature leaves from any and all poplars 

 planted along streets, in yards, parks and nurseries. The 

 name under which the tree is popularly known should 

 be entered on the label, also the current botanical name 

 if you know it. 



If there are such trees within access, will you not aid 

 me to secure specimens? The trees from which catkins 

 are taken should be marked, so that foliage may later 

 be had from the same tree. If catkins and foliage are 

 taken from different trees, in any case, the fact should 

 be noted on the label. Both sexes should be secured, 

 when they exist. Any notes on the label as to size and 

 habit of tree, character of bark, etc., will be very useful. 



Any photographs to show shape and habit of tree will 

 also help me in working up the material. 



An item of cost of the material may come with the 

 specimens and will be promptly paid. 



Of course I also .want any herbarium material of the 



native wild poplars.
