Wrights’, Berlandier’s, Fendler’s and Lindheimer's
plants, which have been lying
for a long time nameless and useless on
my shelves. But still the larger part of 
all these collections still remaining in
my hands, are without names; although
no doubt many of them (nearly all perhaps) 
are embodied in your Report, but
no reference having been made to their
numbers I have not been able to identify 
them. I hope that some of these doubts
will be removed, when I recieve from
Mr. Thurber a set of his Mexican collection,
which he kindly promised me some
time ago; and I will thank you to say to
him that it would be peculiarly acceptable
to me just now, as it would aid 
me no doubt essentially in naming and
aranging these other collections.

I am much pleased to learn that
this gentleman (Mr. T.) is now engaged in
drawing up something like a synopsis of
all the collections which have been made 
west of the Mississippi for some years past,
