 1 7. Root creeping, annular, brown or greyish, and is the Ipeca- 

 cuanha of the shops of Europe, and the Poyas of those of Brazil. 

 Leaves crowded at the tops of the stems, which are simple, and 

 obscurely tetragonal. Flowers white, downy outside. 



Although the root of ipecacuanha has been long employed as 

 a valuable article of the Materia Medica, yet the botanical cha- 

 racters of the plant which produced it remained unknown till 

 Professor Brotero, of Coimbra, determined the genus to which 

 it ought to be referred, with the assistance of observations made 

 in Brazil, on living plants, by Bernardo Gomez, a resident 

 medical botanist. The plant is a native of moist woods near 

 Pernambuco, Bahia, Rio Janeiro, and other provinces of Brazil. 

 It is called Ipecacuanha by the natives of some parts of Brazil ;
