Dr. Torrey

My Dear Sir. I drop you a few lines to inform
youo that a week or two since I sent you & Dr. Gray copies
of my catalogue of plants & that shortly after I mailed
them I discovered a very stupid blunder in my note
under Carex willdenowii (last page). The peculiear structure
noticed in your monograph unfortunately for my note!
was not intended to apply to C. willd.

Most unaccountably, some how or other I misapprehended
the application of your remarks in that case
though my attention had often been directed to the
structure there mentioned while examining the C. willd.

Tell Dr. Gray I would thank him to have my
copy of [Carl Sigismund] Kunth's Enumeration Plant. bound. I forgot to
answer him in my letter of Jan. on that point.

My best respects to yourself & Dr. Gray

Yours truly
Wm. S. Sullivant
