          But I commenced this letter, in order to ask your
judgement, on a point of great interest to me. In my
pamphlet on the Carices, 1843, I separated what I thought
the three species C. bullata, C. cylindrcia + C. monile, 
adopting for the first the plant so called by all Amer-
ican writers on Carices - for the second, the plant with 
Schweinitz's autograph in Hooker's Herbm - confirmed by
another autograph specm in Dewey's Herbm - and for the
3d - the variety cylindracea of vesicaria Dew.
Now Dr. Boott came to the conclusion that the cylin-
drica above mentioned was the true C. bullata of 
Schkuhr - + he therefore was compelled to name anew
the C. bullata of Amern authors, which he did, calling
it C. tuckermanii, with a very kind notice, in his letter,
of my separation of the three species.
But Mr. Carey, in Dr. Gray's Manual - though he has
come to the same conclusion with Boott - that the
cylindrica of my pamphlet (sustained by two autograph
tickets of Schweinitz) is Schkurh's C. bullata - yet
calls the latter C. cylindrica, Schwein. without the
mention of any new authority for the change.
Your Flora was before him which, if I am not in
errour, confirms (and it must be the original authority
if you have Schweinitz's specimens of his plant) my
opinion as to the C. cylindrica of Schweinitz.
In this position of things I am anxious to obtain from
you a settlement of this question - and also of the
question - if Schweinitz's C. cylindrcia is the true C.
