The Species, with us, 



Xanthqxylum fraxinifolium, AJh-leaved Tooth" 

 ach Tree. 



This grows naturally in Pennfylvania and Mary- 

 land; rifing with a pretty ftrong ftem to the height 

 of ten or twelve feet ; and dividing in many branch- 

 es, which are covered with a purplifh bark, and 

 armed at each bud with two ftrong, {harp fpines. 

 The leaves are compofed of four or five pair of lobes, 

 terminated by an odd one; which are entire and of 

 an oblong egg-fhape, placed oppofite and fitting 

 clofeto the common footftalk, which is alfo fet with 

 a few fpines underneath. The flowers are produced 

 along the branches, upon fhort rollcded footftalks; 

 and thofe of the female are each fucceeded, for the 

 moft part, with five diftind, oval capfules, joined 

 by (hort footftalks to the common receptacle, and 

 fpreading above ; each containing one roundifh, 

 fmooth feed. 



There is faid to be another Species, or perhaps 

 Variety, of this in South Carolina, differing in hav- 

 ing the lobes of their leaves lanee-ftiaped, fawed on 

 their edges and having footftalks. The bark and 

 capfules are of a hot acrid tafte, and are ufed for 

 cafing the tooth-ach, from whence it obtained the 

 name of Tooth-ach Tree : a tinfture of them are 

 alfo much commended for the cure of the Kheuma- 

 tifm.
