Page 19* — Ipecacuanha Plants. 
Believing that I may tend to prevent the Ipecacuanha plant of the 
Brazils from being again confounded with the Ipecacuanha plant of New 
Spain', by contrasting their descriptions, I shall annex Brotero’s description 
of the former plant, as contained in the 6th volume of the Linnaean Trans •

Humboldt and Bonpland in Plantes Equinoxiales. Livraison 16. p. 142.
