most enjoyable one.  The weather was ideal. I had opportunity
to note the difference between Barbarea vulgaris and B. praecox.
The flowers of vulgaris seem to be in denser racemes; the pod of
vulgaris are less than an inch long, those of praecox are nearly 2 inches
long.  The leave of vulgaris are courser and of a darker green; the leaves of praecox
are more divided.  The taste of vulgaris is not as sharp as that
of praecox, and is slightly bitter.  Paulownia, Staphylea, [Aurinia], Aralia
nudicaulis, Fraxinus Americana, Juglans cinerea and Quercus were
found in flower.

Botany Class.  Veratrum viride and Trillium cernuum were found
in flower.  At the station we found Lonicera Tartarica.  Here too
we saw a boy with some Cornus florida, the involucre of which
was a beautiful shade of pink. At the Shepherd Asylum
while looking for yellow violets, Ginseng, etc.  I found a floral
shoot of Podophyllum peltatum without the leaves.  The bud
was on a shoot 4 or 5 inches long and came directly up from
the ground.  It was 9 o'clock before we got home.
