Hab. Common on rocky places of the Columbia, near the sea; and at Puget Sound, Douglas. Chamisso 

 found it on the coast of California. — I regret that I do not possess £he fi-uit of this plant ; but there can be no 

 question of the accuracy of Chamisso and Schlecbtendal, who assure us that the cotyledons are accmnhent. 

 It must therefore be separated from Erysimum, with the species of which, and especially with E. lanceolatum, 

 as is well observed, it bears a very close affinity. It is quite a different plant from the Erysimum asperum^ 

 De Cand., the Cheiranthus asper of Nuttall, and which is also supposed to be the Erysimum lanceolatum of 

 Pursh; but I know not upon what authority. I am indebted for specimens to M. de Chamisso, which agree 

 in every respect with those from Mr. Douglas : both are remarkable for the great attenuation of the base of 

 the leaves. It has been found by no other of our North American travellers : but is now cultivated in the 

 gardens of the Horticultural Society, from seeds sent by Mr. Douglas from the Columbia.
