My dear Mr. Deane 
Under separate cover, I take pleasure 
in sending you a copy of my study of the 
Scrophulariaceae of the New York and 
Philadelphia region. I hope that this 
may be of some interest to you. 
If I can assist you in any way in the 
naming of the species of this family, I 
shall be glad to do so. If you wish me 
to examine the New England specimens of 
Penstemon, I shall do so. You will recall f£Lc*j*=- 
I noticed that Pens temon pallic^us had not 
been separated from P^ hirsutus , and I am 
anxious to determine the northeastern ranges 
of these and o Iher species. The species 
of Penstemon have flowers very distinct in 
color and form of corolla, and field study 
has shown the great distinctness of certain 
species which are recognized in the Herbarium 
only with difficulty. 
Very sincerely yours, 
W-
