          a copy of the Am. Cyp. with Dr. Gray's invaluable monograph
+ other work at the end. And here allow me to state a difficulty
which I have found. I found among the Cyperaceae in the package a
fine specimen of "Ceratoschoenus corniculatus" form "Louisiana". This I endea-
voured to examine but with only the following success: Instead of the oval
shaped nut represented in the plate to Gray's Rhyncosporae - I found only
a long subulate body surrounded with what seemed very long bristles. I think
it must be imature: but was I mistaken in supposing the bristles so long?
I am sensible I may very probably have committed some mistake here
though I examined a good many spikelets with the same result.
But I have forgotton to think you for some of Dr. Richardson's
Carices. These I value highly indeed. And also for the grasses which
are all so interesting. But I must stop here. 
The grasses  + carices new to our Boston region that I have found
as yet are the following + Paspalum ciliatifolium, Digitaria glabra,
D. filiformis, Panicum clandestinum. Carex oederi, rosa, muricata,
filiformis, virescens, sylvatica, - These at least are the most interesting.
Beside these I have a small subalpine Eriophorum, which Mr. 
Nuttall allowed to be what I had marked it, a subalpine form of
E. polystachyum. This grew on the Grand Monadnock enter[?] in NH. But
What is more interesting I think I have found Chrysosplenium [?] alter-
nifolium. I gathered a single specimen only + that not entirely satis-
factory in a subalpine rivulet on the Green Mts of Vt. The leaves are
alternate + the plant appears not only to differ from C. Americanum
but also to resemble the plates I have seen of C. alternifolium.
According to Hooker it would seem this has not been found in the
U.S. I shall examine it again, + if I do not find that I
am in error, I will send it to you: though, as I have no other
