Engelmann, George Mar. 9, 1843 [3] (seq. 80)

I have received a letter from Hooker, written after he had seen
my Cuscuta paper. He requested me to send him specimens
of Cuscuta, encouraged me to go on in that way and asked wether I
would not undertake a monography of the family; and offered the
loan of his herbarium! — He appears to have not known any thing
of {Jacques Denis} Choisy's monography. I answered him, after that it would
probably
be a superfluous undertaking now, but if he wished it, I thought
it still useful I was very willing to do it — as I feel a great
interest in that genus now. — He asked whether I myself or any
body else would go up the Missouri and collect — and in that
way he prepared the way for my propositions of Lindheimers and
Geyers (and Lüders perhaps) collections. I wrote him of
their plans. — I sent him also a description of my Lindheimeria
as I wanted to have an interesting, remarkable genus dedicated to
my friend. — — In the parcel for you is a small package of
Cuscutae which I request you to forward to Hooker.

I hope to get an early answer from you; and learn from you
that you got the seeds safe, and that they begin to germinate.
The roots collected for you appear to be all killed by our extraordinary
long and hard winter. Then is still snow in the streets to day,
When the Erigenia ought to be in bloom!
I will try to get roots again when the ground opens.

Yours entirely!
G. Engelmann
