 leaflets ovate, obscurely sawed, equal 

 at the base ; the petiole round and de- 

 void of prickles; prickles in the situation

 (Dec. Prod., i. p. 726, 727.) A low 

 deciduous tree, a native of North 

 America, from Canada to Virginia and 

 Kentucky, in woods near rivers ; culti- 

 vated in England since 1740, and flow- 

 ering in March and April. In its 

 native country, this tree is seldom 

 seen higher than from 12 ft. to 15 ft.; 

 but its stem is decidedly that of a tree rising to the height of from 

 3 ft, or 4 ft. without side shoots, and then branching out, and forming 

 a regular head. The flowers are yellowish, with red anthers. The bark and 

 capsules are of a hot acrid taste, and are used for relieving the pains of the 

 toothache; whence the popular name. A tincture of the"!)ark is also used 

 for curing rheumatism. This tree is common in British collections, but is 

 never seen of any great size. There is one at Syon, about 13 ft. high ; in 

 the Cambridge Botanic Garden, one about 10 ft.; and some at White 

 Knights, from 10 ft. to 13 ft. high. In the Edinburgh Botanic Garden, 10 

 years planted, it is 6 ft. high. It is generally propagated by seeds or by 

 cuttings of the roots. Plants, in the London nurseries, are 1*. 6d. each ; at 

 BoUwyller, 1 franc and 20 cents ; at New York, 25 cents, and seeds 1 

 dollar a quart.
