          four plants which my hasty
examinatiton did not suffice to
determine. Do inform me what they
are; I have short notes sufficient to
recal the plants to mind, if your
information is early. C appears to be 
a Phacelia, certainly one of the
Hydrophyllaceae; a new Phacelia?
or Hydrophyllum Canadense? with
which I am not acquainted.

I have selected and retained
Hypnum two species
Atrichum?
Barbula
Tiarella cordifolia, in fruit. I obtained
it in flower near the N.C. & S.C. line last
April (1852). The first time (as far as I 
am aware) that it has been found so
far south.
Phacelia bipinnatifida? correct me
if wrong specific name.
