Hab. Arctic America, from the East to the West coast. J)r, Richardson. — To the above excellent de- 

 scription, 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 tubers, in which particulars it differs from Dentaria heterophyHa, a plant in other respects very 

 nearly allied to it. This species has been found by Chamisso in the GuK of St. Lawrence, on the Asiatic 

 side of Behring's Straits.

Hab. Banks of the Columbia. {Herb, Lewis.) Mr. Menzies. — Mr. Menzies' specimens agree precisely 

 with my Siberian ones from Dr. Fischer and Professor Ledebour, They scarcely differ from Dr. Richard- 

 son's Cardamine digitaiaj 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 Car- 

 damine.
