Hab. Arctic America, from the East to the West coast. Dr. Richardson.—To the above excellent description,
made by Dr. Richardson from recent specimens during the First Expedition, I have nothing to
add, (since the perfect fructification has not even now been detected,) except that the root is creeping and
destitute of tqbers, in which particulars it differs from Dentaria heterophylla, a plant in other respects very
nearly allied to it. This species has been found by Cham\sso in the Gulf of St. Lawrence, on the Asiatic
side of Behring’s Straits.

Hab. Banks of the Colombia. (Herb. Lewis.') Mr. Menzies.—Mr. Menzies’ specimens agree precisely
with my Siberian ones from Dr. Fischer and Professor Ledebour. They scarcely differ from Dr. Richardson’s
Cardamine digitata, except in the tubercled root, and in having fewer leaflets; and that plant should
probably be referred to Dentaria, a genus, indeed, which Mr. Brown only considers as a section of Cardamine.

H ab. Found during the Second Land Arctic Expedition, and then only by Capt. Sir J. Franklin and
Capt. Bach, to the west of the Mackenzie River. Frequent on the shores of Kotzebue’s1 Sound, and the
adjacent coast. Lay and Collie in Capt. Beechey's Collection. Island of St. Lawrence. Ghamissol— This is
a noble species of a beautiful and well marked genus, worthy of bearing the name which Mr. Brown has
applied to it, in compliment to an officer of the most distinguished merit, who has, in every voyage, particularly
to the Arctic regions, by his own exertions, and by those of his officers, contributed mainly to our
present accurate knowledge of the botany of those countries; and whose friendship to myself I am here
proud to acknowledge. Capt. Sir John Franklin only met with the plant in flower. Capt. Beechey’s collection
contains many fine specimens in fruit, from which the figure of that state is represented in this work.
