not of Michaux, (which is indeed a nonentity made of frag- 
ments of several species.) He found it growing in valleys, 
near springs, on the West side of the Rocky Mountains, 
near the sources of the Columbia. We also met with it in 
a lofty ravine on the 3 Butes, tw’o days march to the west 
of Lewis’s River. The real Sugar Maple is said by Torrey 
and Gray, to grow as far west as Arkansas and the Rocky 
Mountains.

This fine species of Maple was discovered by Drum- 
mond and Professor Carpenter, in Louisiana. It is found 
exclusively in very low swamps, generally subject to inun- 
dation, and flowers in February, 3 weeks earlier than any 
other species in the same country, according to Professor 
Carpenter; he met with it more particularly in the swamps 
of Opelousas. 
This tree, though allied to the Red Maple, appears to be 
sufficiently distinct from that species, as well by its general 
appearance as its geographical range, as yet being only 
known to the swamps of Louisiana. I have also been told 
of its existence in the province of Texas.
