Dear friend,

You may recollect having received a Helianthus
from E. James, which you wrote him, seemed not described.
We have just ascertained that it is the Heliopsis laevis.
Tracy first suggested the thought. I wonder we had
not discovered this before. As this [?] and grows every
where, and as it is not yet down in your catalogue
I presume you call it Helianthus frondosus.

We have found three specimens of the Campanula [acriminata?]
here. I hope to find plenty of them here; for
one of our young ladies says she saw them last summer
in great plenty near Lansingburgh. My boy, Dwight,
found our specimens a mile before Troy.

I shall send you a Leersia, to see whether it is your
orythordes. It appears to me to agree with Push's
lenticularis.

The plant, which you are inclined to call Fucus, was the one
about which my enquiries were made. I put in the
Sparganium after the letter was sent. I knew it was natans.
I found the unknown plant at the bottom of the lake
on Catskill Mt. where the water was above four feet
deep. [added: There are cart-loads of it] I took it for some plant of the order Algae; 
perhaps a Jungermmania. I found the same plant in Tyningham, Mass.

My new Sparganium I find described in Nuttal
under his new species americanum.

Dewey says, you make a new species of my Oryzopsis,
which I found at Williamstown. But E James says it
agrees very nearly with Oryzopsis of Micheaux. Ives
and I made and Oryzopsis of a [crossed out: plant] grass I send you
now. What is it? It abounds at N.[North] Hampton and
New Haven.

I have a desire to correspond with the "Great men
of Europe", If I could [added: find] a really good liberal fellow. But
I find most of the Scientific Europeans mean and 
selfish. I would not send a package, unless I could
do the business justice. Perhaps I may prepare
something next fall.
