          When Dr. Gray returns from Europe I would like to
confer with him concerning some localities of interesting
plants in this region. The Trollius laxux I have never found
and several Carices which he mentions as being found
near Utica, I have sought for in vain. Carex Davisii
occurs very sparingly at the great bend of the Mohawk and
only on the Northern side about 1 mile from Rail Road
Depot. Carex longirostris I have only found on the banks
of Fish Creek in a single cluster or clump from which
all my specimens were obtained. C. chordarrhiza, C.
livida, limosa & var irrigua I have only found in
a swamp near this village. This swamp is undergoing
the process of clearing off and without doubt the spe
will [added: enjoy] a habitat here, but a limited time. C. blepharo 
I found 4 years since in the town of Rome 2 1/2 [remainder missing at torn margin, but "miles" is found attached to page 1 of 21 FEB 1839]
West of the Village on the site where Fort Bull
formerly stood rather sparingly but I think 100
specimens might be obtained in one season.

I know a locality of a plant which I believe
is rather rare. It is Lygodium palmatum Schweinitz.
Pittston Luzern Co. Pa. I saved only 3 specimens one I
gave to Dr. Gray another to Dr J. S. Douglas formerly of Vernon
and one I retain myself.

I flatter myself a valuable
addition to my collection if nothing should veto my
plans of collecting the present season.

I have studied those plants (with much gratification)
which you gave me, & have also studied with
care the Flora as far as published likewise your
Monograph of Cyperaceae etc. etc. etc. Please write
to me soon.

My family is well.

My respects to Mrs. Torrey & the children.

Believe me truly yours
