Dr.N.D.Britton,
Columbia College, New York City;
Mr Dear Doctor:-
I have your letter of Dec. 1, and will say
that within a few days I can send you a packet containing a number of
species of Psoralea, and some of Lupinus. As to Astragalus I am not
so sure whether I can furnish you with material which can be of value
or not. That species is such a bad one that I dislike to work with
it. Our species of Psoralea are in need. I am sure, of a thorough
revision. A student of mine, Mr. Rydberg, who made some collections
in the section part of the State during the summer, has been studying
over out species, and I will enclose in the packet the notes he has
made, Mr.Rydberg is a Swede who graduated from one of the Swedish
colleges, and hs been for several years in this country. He is now
spending a year with us, and is devoting considerable time to botany.
You will find his notes quite instructive.
I am quite confident that, in some cases at least, species have
been combined where they are, in fact, distinct. The notes by Mr.
Rydberg, however, will bring this out, and I need to speak of it par-
ticularly here.
