Hab. Island of Orleans in the St. Lawrence. Mr. Skeppard. — The only specimen of this plant I have 

 received from the Canadian possessions is destitute of flowers, but its petioles, winged with the decurrent 

 base of the leaves, admirably distinguish the species. The stipules, indeed, are not cordate, nor are they so 

 figured by Watson, nor described by Michaux, except in the young state. It were to be wished that 

 the other American species of this genus were as distinctly marked as the present. But the whole of them 

 require careful comparison, and to be described from recent specimens. 



Dr. Morrison's collections from Newfoundland contain the C oxyacantha; but it was probably intro- 

 duced into that island from Europe.

 Rapids, and at Fort Vancouver, on the Columbia, and on the high grounds of the Multnomak River. 

 Douglas. — I am sometimes disposed to agree with Dr. Torrey, who suspects this to be only a var. of the 

 preceding. "What I consider as the A. Botryapium has the young leaves slightly hairy, and the adult 

 ones perfectly glabrous, of a thin texture, and turning black in drying. In my specimen of A. ovalis, even
