HAB. Woods. Throughout the U. S. July. One of the largest 

 trees of our forest. Leaves alternate, 3-lobed ; the middle lobe 

 truncate. Flowers solitary, large, of a dull yellow colour. Ac- 

 cording to Dr. Darlington there are two varieties of this species, 

 differing chiefly in the colour and texture of the wood ; the one 

 being yellow and the other white. The yellow is the most val- 

 uable, but both are employed extensively by cabinet makers. 

 The bark is a valuable tonic, &c. See Big. fy Bart. Med. Bot. 

 Dr. P. K. Roger's Inaugural Thesis, PhUad. 1802. Dr. Emmet 

 has found its virtues to reside in a principle which he denomi- 

 nates liriodendnne. See Jour. Phil. Coll. of Phar.
