Dear Sir
I have received your letter apprising me of your
safe arrival in New York, and congratulate you upon your
pleasant voyage. I am glad to learn that you have made such
good use of your time while there, and anticipate that much doubt
and confession among our plants will be cleared up y your visit.
You mention a good many clever fellows whom you have seen,
but do not say any thing of La Pilaye [Bachelot de La Pylaie], and his Flora of Newfoundland
a man who appears to be one of the right sort, and who made
a pretty full examination of that island.

I was disappointed in not seeing Dr. Gray, having been informed
by letter from Dewey that he would call on me.  I am glad
to learn that he has got more of that Evolvulus plant, which certainly
does not belong to that genus. It comes nearer to Convolvulus
trichosanthes that to any plant I am acquainted with, but
differs in the form of the calyx. When I showed the plant to Le Conte
some years ago, he declared it to be the Evolvulus of Elliot, but on
speaking to him on the subject a few days since (after he had seen 
Gray's specimens) I found he had doubts. The species of Evolvulus that
I have seen differ altogether in habit. I have a Eupatorium from
Quaker bridge, for which falcatum would not be an unappropriate
name, but whether it is identical with the species so called in the 
books, I have not determined it grew in high ground & has almost linear
leaves, the E. linearifolium [Eupatorium linearifolium] is not uncommon there in the marshes.
The Artemesia I did not meet with there, but suppose it is the
same with the caudata? of the sea coast of New England. An Isnardia
is common there, which has a pithy production about
the lower part of the stem, and much smaller flowers than
