Dear Mr. Weatherby: 
I owe you an apology for not answering sooner your letter of 
sometime ago in which you asked for suggestions as to plants appro¬ 
priate to «. map in working out Hew England areas. I have been so 
very busy with one thing or another that your letter slipped by with¬ 
out an answer, particularly as I imagined you would be up again soon. 
I started working up a list and very soon found that I was includ¬ 
ing all the ferns and fern allies with the exception of very few ( Poly ¬ 
podium vulgare , Pteridium aquilinum , etc.) so that I would suggest 
that as a first try out the Polypodiaceae and Ophioglossaceae be taken, 
because they will bring out essentially all the areas we have, except 
perhaps some of the coastal plain special areas. I have worked on Dr. 
Eames' package two or three days and there are still snaggy things. 
The material is chiefly introduced stuff and under one number he had 
three entirely distinct species of Linaria , differing in technical 
points of the corollas and of the calyx-lobes and pubescence, as well 
as in the color, which he had taken offhand to be merely color-varia¬ 
tion of one species. It took nearly a day to run these things down, 
but I finally landed them^all species knov r n only from Spain, Portugal,
