          [?Wsilizenia] does to Oxystylis! He is so near it that I have
written to Dr W. if it is yet time to alter it in printing
and mention it as a second species of [?]. Is your
[Iberis?] n. sp actually V. geyeri? I thought it must be
my Drithyrea! which is very near Bisontella and not
[?].  at first glance the shape of the flat
[?iole] and the short style with the large [?date]
stigma distinguish it - one horizontal seed etc.

Where does Nuttall publish his N. Mexican and California
plants! I should like to get a copy if possible.
And what are the [obsured:principal?] works where the
plants of northern Mexico are published? I ask
in refernce to Gregg's and Wislizenus plants.
I have mentioned only a few of them as you know
principally from fear of collision with others.
I should like to learn your opinion about my
6 new pines  are they really new? The analogy
of the 5 leaved pine of [crossed out: Chihuhua] [added: N. Mexico] (your P. flexilis)
and that of Chichuahua (P. strobiformis w. [?]) with
P. strobus is very interesting, but they are very distinct.

Your propostion in relation to the Exploring Expeditions
plants is very flattering, but after mature consideration
I am obliged to decline it. If I followed my
inclinations I would accept at once, but my
botanical knowledge is [crossed out: such] [added: so imperfect] that I would have to study a good deal [crossed out] only to begin to be
able to do justice to the work. I would further
have to give up at least to a great extent
my medical practice, which now occupies my
time almost entirely, and just begins to become
lucrative. And then the necessary trip to
Europe would destroy it entirely. But still I
should like it so well! I feel very much
as I did when my old friend Nicollet 1838
proposed [added:to me] to accompany him on his north western tour.
