Drummond.—My valued friend Dr. Boott has ascertained that the Arabis rhomboidea of Pers. is the same
as the Cardamine rotundifolia of Mich.; a much more appropriate name. Our plant differs somewhat from
the United States specimens, in having fewer1 leaves on the lower part of the stem, in the upper leaves being
somewhat broader, and in the pubescence of the foliage, and especially of the stems; but these characters
depend perhaps upon age and situation. The flowers, too, are large, the petals rose-coloured. The shape of
these petals in both is nearly cuneate.

H ab. Islands of St. Lawrence. Chamisso. Cape Lisburne, at the northern entrance of Kotzebue’s
Sound. Lay and Collie in Captain Beechey’s Collection.—Only one specimen of this very beautiful Cardamine
exists in our collection. It is distinguished at once by the 3 (5 in Chamisso’s plant) roundish leaflets
of each leaf, and the deep purple-coloured and reticulated petals, in which latter particulars I know of no
species that comes near it.

Hab. Banks of the Columbia. Scouler. Douglas.—Somewhat allied, especially in habit, to C.macrophylla,
{Gmel. Sib. v. 3. t. 62,) which differs in having smaller leaflets, from 5-7 on each leaf, and which are distinctly,
and with considerable regularity, serrated; whereas, in our C. angulata, there are few and distant
angular teeth and segments. I have seen it only in Mr. Douglas and Dr. Scouler’s collections, who observe
that it is not uncommon about Fort Vancouver, on the Columbia.

Hab. From Canada to the Rooky Mountains, and to the shores of the Arctic Sea. Drummond. Dr.
Richardson. Unalaschka. Chamisso. Columbia. Scouler.—Those who have been in the habit of observing
C. hirsuta, as it grows with ns, in different soils and situations, and at different seasons of the year, are well
aware how liable it is to vary in size and ramification, in the direction of its Btems, in the breadth and
length and toothing of the leaflets, and somewhat too in the size of its flower. :Even the style is more or
less distinct, sometimes quite obsolete. The same states occur in North America, whence have arisen the C.
virginica and C. pennsylvanica; this latter being eaten in Charleston, South Carolina, Mr. Elliott tells ns
like the garden Cress, as is our. C. hirsuta. My specimens of them quite correspond with our Enropman
states of the plant. I have placed a mark of doubt against the C. parviflora of Dim., because Sir James E.
Smith says it is clearly a distinct species; yet he refers to Gmelin’s FI. Sihirica, v. 3. t. 64, which perfectly
accords with many of my. American and English specimens, such as are but varieties of C hirsuta The
species is probably very extensively distributed over the globe. I have it from Nepal and from Chile * It
exists, too, in Persia.
