          Although I don't buy plants now, I would give him $10 cash for
200 Southern plants lacking in my herbarium, and would buy $50 worth
if he would take Books or plants in exchange.  As to his grapes, I must have
yet a copy, if he can spare it, when complete, the unbound set at $3 p [per]100
and will give him some Books on plants in exchange.  500 grasses & cypereceae
will come to $15.  I have many rare Botanical Books to spare you know
Annals of Botany, flora greca prodromus, Aiton hortus Kewensis, Gmelin
Linneus Opera miscellanea, etc.  Try to make this bargain for me, but I cannot
pay cash for grasses now.

I have added to my plants, som pamphlets, my Principles of Somiology
which pray read again (if ever you did).  Some copies of my herbar Rafinesq
which you may distribute to your correspondants - and several msts
Papers.  1.  Botanical Remarks on Criticism, which you may use or
publish, and avail yourself of in any way.
2.  Catalogue of my 80 plants from Oregon, almost all new, Descr. [description] sent
to France, Specimens yet with me.  we went over them together last fall.
Communicate this to the Lyceum if you like.
3.  Catalogue of the 50 Crucifera in my Herbarium, several are new.
My N.G. [new genus] Platoptera you saw.  I have made the N.G. Oclerosis from the
Hesperis pinnata of West & have 4 Sp. [species] or varieties as you would call them
in sessile, and entire.  My Dileptium of 1817 is a good genus 2 stamina
instead of 6, is quite generic and anomalous in the family.  I have 3
Sp [species].  My Discoreum is good G [genus], you saw it.  Myagrum argenteum is perhaps
a 2d Sp, but I have no seed, have you?  Send me or ascertain it.
The G. [genus] Kernera of Miench is old & good.  The G. Arabi, Cardamine,
Turritis, & Solynchium are yet obscure to me & I have many doubtful specimens
if not species.  If you want some of my Crucifera for your study
I will lend them to you, as this is a family I have yet surveyed to my
satisfaction.  If you have any Sp. [species] not in my list to spare I will thank
you.  I have also a N.G. [new genus] from Asia & Palestine!  Iondra arabica
the Thlaspi arabicum of books, the G. [genus] Thlaspi is yet very uncertain even
after Decandolle labours.  It requires revision & also Iberis, Sisymbium, etc.

I have been revising my herbarium over again this winter & worked
upon it, particularly on the Genera Lobelia, Polygonium, Polygata, Potamogeton,
Plantago, Ranunculus, Lonicera, Triosteum, Harpalyce, Lactuca
Prunus, Amphicarpa, Parietaria, Asarum, Sagittaria, etc, their monographs
are much increased.  Our 2 Triosteum are now increased to 7 distinct
Species, & the rest in proportion, upon which I depend on much as you do upon
your 150 Carex & 150 Cyperacea! which I might deny just as easily by
a sweeping denunciation as you might my own long studied species.

I have had the pleasure to find in my herb. among doubtf [doubtful] Leguminosa a N. Sp [new species]
of my G. Browburya of fl. ludov, 1817 which thus become confirmed.  I hope
there is no other Browburya, altho' I think I saw one somewhere since.
Now tell me is not this a good G. [genus].  Cal. bibract. camp. 5 fido. corina & stylus
incurvis hamatis.  Scandens fol. termatis.  It is neither a Galactian nor Dolichos
nor Glycine.  Say then what is it?
