          I have specimens of P. purp. [Paspalum purpureum] which I at first referred to P. plicat [Paspalum plicatulum]
on the strength of a very singular fold running across the flat valve
of the Calyx each way (thus [a cross inside a circle]). I examined several specimens of it
and all agreed in this character, but it has disappeared in drying.
Is not P. debile Mx [Paspalum debile Michaux] a var. [variety] of P. setaceum [Paspalum setaceum]?I once found a specimen
near the sea coast agreeing with the former in all but the pubescent
stem, but it was evidently a stunted P. setaceum. I rather think
I have lost the specimen. The Silphium, which I set down
to S. pinnatifidum E. [Silphium pinnatifidum Elliott] because it came nearer to that than any other,
I had intended to offer as a new species previous to my plan of
resorting to your aid. You do not decide positively upon it. I should 
like to have your opinion. Coreopsis (a), in your list "C. lanceolata [Coreopsis lanceolata]?",
has give me a good deal of trouble. It differs very materially
from my specimens of C. lanceolata [Coreopsis lanceolata] which agree exactly
with the description of Ell. [Elliott]. The flower & seed comes nearer to
C. gladiata [Coreopsis gladiata], than to any other species which I know, but differs in
every other point. It is always erect, smooth, leafy, nearly to the top,
where two or three peduncles diverge; while C. lanceolata [Coreopsis lanceolata] is procumbent,
often having no proper stem, with remarkably long, axillary
peduncles; & is thicker in all its parts, more pubescent, and with
different shaped leaves. I describe from memory. But I shall call
it C. lanceolata [Coreopsis lanceolata], unless you alter it. Gerardia (e) & [partially erased: G.]
G. [Gerardia] (c), which you consider "uncertain", I find marked
the first, G. [Gerardia asciculata]; the other G. setacea [Gerardia setacea] of Ell. Sketch [Elliott's A sketch of the botany of South-Carolina and Georgia].
G. [Gerardia] (b) = G. linifolia N. [Gerardia linifolia Nuttall]. I have a specimen of Gerardia
from this vicinity (G. tenuifolia [Gerardia tenuifolia?] Bw??) with the leave & peduncles 
in threes, verticillated like a Lysimachia. This is a novel character
to me, have you ever found it? Have you got
Elliott's Gratiola acuminata? I have fallen into a great error
if Le Conte has not a very reckless remark upon this plant and 
the Herpestis cuneifolia of Ell. [Elliott]. I never had any doubt of Ell's [Elliott's]
correctness until I saw Le Conte's article, & I do not know whether 
to regard his assertion as sufficient authority to change my opinion.
I have no means of ascertaining the original G. acuminata [Gratiola acuminata]
so that E. [Elliott] may be wrong for all I know. But I believe his H. cuneifolia [Herpestis cuneifolia]
is right. What is your opinion of G. acuminata Ell [Gratiola acuminata Elliott]?
You mention two specimens of Ludwigia under one letter (b). If you 
find the leafless one different I should like to know its name, as
I have no memorandum of any by that No, [number] except, L. virgata Ludwigia virgata], 
Andromeda (a) you refer with uncertainty to A. ligustrina [Andromeda ligustrina], 
but if you can possibly arrive at any certainty upon it, I shall
be very glad, as I have become utterly confused in that class] of Andromedas
which Nuttall calls Lyonia.
