          My investig. [investigation] of the G. [genus] Amphicarpa is very curious.  I have 6 species, 3
are 3 sp [species] & 3 are 2 sp. with acute calyx & no petals! forming sub G [genus] or G Lobomon
Not 2 Amer. [American] botanists agree in their characters, some having see &
descr. [described] 2 of the 6 & another the others, all differ in leaves!

Many of the species described in the books are in a state of great confusion
because the character assigned to them are of very little value.  These are yr [your]
wond words in y [your] letter of the 1st ab [about] Cyperacea & applies to 100 other genera.
Then why don't give me credit when I investigate deeply a Genus or several.
Since you offer to lend me some plants, do lend me those of the genera above mentioned
if you cant spare them.  Also Gentiana, Commelina, Rudbeckia, etc.

I will gradually lend you all my doubtful & unpublished species as you
proceed in your work, provided you give me credit for the name & discovery
& I will allow you to describ [describe] them & figure them, but not to destroy them
by analysis of seeds.  The Genus I will always determine too well without it.

You are aware the Commelinas like Orchis must be seen alive for the 
generic character, thence our 4 Sp. [species] belong to 3 different Genera, Nephralles,
& Larnalles & I have 10 species out of the 3 genera, besides the Ananthopus
of fl Ludov. which must be a 4th genus of Commelina.

Nuttal has 113 plants of Oregon & I have 80 [added:nearly] all different, my collection
dates of 1825 & ought to have been published before his yet we do not interfere
having but few similar Sp. [species] Lupinus sericeus, [Polemonium mexicanum] etc but his Oxytropis
lagopus is my Ox. bradburri fl. mandanensis 1817 & Autokon 1833.

Among the 83 Rare plants he has described from all parts I claim a dozen as
mine, long known or described.  1. Jeffersonia lobata Raf 1830 Etc.
Cynthia lyrata & [Cynthia griffithii].  N. my Krigia lyrata & heterophylla known
since 1818 & 1802!  Why is the G [genus] Krigia abolished I can't tell, can you?  It
as made by Schreber on our Hyoseris virginica!

Rhamnus shortii N. appear diff [different] from my Cardiolepis by fl. 4 ands apet.

Physalis walteri N is my [Physalis floridana] Autikon 1833

Is it not shameful in Nutal to have a G. Malvaviscus instead of Achania
and pray what does he mean by Rudbeckia apetala!  Torrey, is it a blunder of
yours, Rudbeckia has no petals but rays!  and if no rays it is no Rudbeckia.
All the Bidens with rays are Auradium G all Senecio with rays, Jacobea G.

I have called all the Euphorbias with a 5 lobed corolloid Invol. Petaluma
may adopt this fine G [genus].  I have 6 Sp. of it.  [Euphorbia leucoloma] & graminis belong to it
the old genera Chamexyce, Erula, Characias, Tithymalus, Paralices etc
must be restored as G. or subgenera.

My N. G of Orchidaen Tulotis 3 Sp type O. herbiola, 2 other N Sp [Tulotis fragrans]
& [Tulotis albiflora] find Sp from the White Mts [mountains] found by Dr. Stevens.  All have odorous
flowers, labellum with a gland or nectary shaped thus
[sketch] Tulotis herbiola
[sketch] Tulotis fragrans
[sketch] Tulotis albiflora

The Orchis spectabilis is also a peculiar G.  I am
convinced of it.  I call it Galearis.

When can I visit your herbarium?  if ever.
When will you be fixed in N. Yk [New York] & disengaged.  I want to spend 3 days on it.

I hope this letter will satisfy you & prove you again my zeal & activity in
Botany if nothing else.  I want another Letter from you, or write me from
Princeton & make it a long one, answering enquires & give me some solid matter.

Keep this letter for reference.  I hope that when yr [your] correspts [correspondence] write you have this
& synonyms you make an entry in your memoranda.

Respectfully, as usual, your sincere friend, C.S. Rafinesque
