          has the [?] smooth opening regularly by 2
[?] and leaving the partition or the receptacle
cells 2 parallel, both fertile without aobut two
dozen seeds in rank - cotyledons angular, often
nearly rhomboidal, resembling the granulations
of the mineral caccolite. It is certainly 
an araba or the diagnosis of that genus is very
imperfect. You might question the stigma's
being sessile. But it is sessile, and the appearance
of a style in the prolongation of the partition,
as in the Sinapis, dissepimentum prominens.
You ask whether I ever saw a yellow
flowered Draba. Persoon says the Draba 
nemoralis is yellow. This may not be the
[Arabijons?] but Persoon says the silicle of the
[Arabijons?] is rendered accuminate by means of
the styli. He would have been more consistent
with his generic description to have [?]
by means of the elongated partition. But
we know what he means, and this character
is found in my Draba. As he give 
[Arabijons?] as a synonym or Arabis, I think
our is a new species. It may be called 
Araba lyrata. Its diagnosis may be thus:
stem leafy branched; [?] leaves lyrate, 
upper ones sub-pinnatified. The Draba you
sent me is certainly as much like it
in habit as we can suppose, since it is
under a different section; which is far 
from an artificial difference.

Yesterday I collected several additional
specimens of [added: our] Muhlenberg & [?]
for you. Have you the Staphylea [trifoliata?]
