          They consist of perhaps 50 species
I think nearly all new, but as
yet have given them very little attention
I recognigze aming [among?] them, a Platanus
unlike either of the American spcs.
A Populus, also new. Alnus. Betula
etc.

[Thuja?]. Juneperus [Juniperus]. Taxodium etc.
(no Abies) , beside many [?] which
I do not recognize. some fruits & flowers

[Would?] [you not?] like to take a peep
at the botany of the N American
Continent of an Earlier age than
that which you have so carefully
studied?

If you will some time come
to Washington, You shall have that
pleasure.
