West-Chester, Penn. Decem.14. 1827.

Dear Sir,
I now have the pleasure to forward, herewith,
such of the specimens in your list of Desiderata, as I
have been able to procure. The season for some of
them had gone by, when I received your list; and
others, being somewhat rare, I have not had the good
fortune to meet with: But if I live till another
year, I will endeavor as far as practicable
to comply with your request. I had, in the
early part of the season, sent away all my du=
=plicates of our rarer plants. —

You enquire respecting the Southern boundary
of Caltha palustris. I am unable to answer
further, than that it is very common here, and
I think, also, it is frequent about Washington City — which
has been the extent of my observation to the South. The
Ranunculus marilandicus, of which you desire a speci=
=men, is unknown to me: though it may possibly grow in
this region. I am not very well acquainted with that family
of plants. Some of the species seem to me to be difficult
to distinguish, by the descriptions in the books. The Agrostis
stricta, of my Catalogue, which you have asked for, Dr. Torrey
pronounces to be nothing but an Aira. I inserted it on
the authority of Mr. Schweinitz, who examined the specimens:
but they were not good ones — and he appears to have fallen
into a mistake. —

I shall be extremely indebted to
you for any of the Southern plants contained in the list
which I forwarded to you last spring, and which you have
not already favored me with: and if at any time you
should desire specimens for yourself, or your correspondents,
of those which are to be had in this vicinity, I hope you will
freely command my services, so far as I am competent to
render any. It will give me great pleasure to be able
in any degree to return your kindness. —

With the highest respect,
I am, Dear Sir,
Your obed.t servant,
Wm. Darlington
