Scouler. This plant varies much in its stem-leaves, which are more or less oval and oblong, elliptical or
lanceolate, or sagittate, pubescent or quite glabrous. It is remarkable for its numerous, erect, shining, very
strait pods. I do not see how A. sagittata is to be distinguished from it. My European specimens, under
that name, quite agree with the British, and with my American A. hirsuta.

—Authentic specimens of Arabis lyrata, from Dr. Schweinitz and Professor Torrey, and from Dr. Richardson,
I have compared with our European A. petrcea, and find them to be in all respects the same. The plant
is doubtless liable to much variation, being sometimes, indeed generally, quite glabrous; at other times the
root-leaves and base of the stem are hispid with branching hairs. The pods are mostly nearly erect, but sometimes
almost patent; generally scarcely an inch long, at other times full two inches long; mostly with an
inconspicuous style, at other times with a very apparent one. Flowers white or lilac. It comes exceedingly
near to some states of A. arenosa; and I fear cannot specifically be distinguished from it.
