an heirloom of primitive European medication, trans- 

 planted to the settlers of the American wilderness, who 

 added the stramonium to hyoscyamus. 



IPECACUANHA (Ipecac) 



Official in every edition of the U. S. P., from 1820 to 1910. 

 The U. S. P. 1910 makes official the root of Cephaelis Ipecac- 

 uanha (Rio Ipecac of commerce) or of Cephaelis acuminata 

 (Cartagena Ipecac). 



The plant which produces this drug, Cephaelis Ipeca- 

 cuanha, Richard, belongs to the large natural order of 

 Rubiaceae, which includes a large number of our medic- 

 inal plants, for example cinchona, spigelia and mitch- 

 ella. Different authors have successively assigned 

 the plant to different genera, (Index Kewensis, 1894), 

 as follows: Uragoga, Linnaeus, 1731, Psychotria, Lin- 

 naeus, 1759, Cephaelis, Swartz, 1788, and Callicocca, 

 Schreber, 1789. The following synonyms now exist: 



1. Uragoga Ipecacuanha, established by Baillon in 

 1879, (Baillon, Nat. Hist. Plants, Vol. VII, p. 280, 

 London, 1881), evidently by right of the priority 

 claimed for the generic name, Uragoga. 



2. Psychotria Ipecacuanha. This is the name now 

 recognized by the Index Kewensis, in which Stokes, 

 Bot. Mat.Medica, (1812), is credited as introducing the 

 name of the species. The name was again author- 

 itatively proposed in 1881 by Miiller Argoviensis 

 (Martius, Flora Brasiliensis, fasc. 84, 1881). 



3. Callicocca Ipecacuanha, Brotero, 1802. 



4. Cephaelis Ipecacuanha, Willdenow, 1804. 



5. Cephaelis Ipecacuanha, De Candolle, 1804. 



6. Cephaelis emetica, Persoon, 1807. 



7. Cephaelis Ipecacuanha, Tussac, 1813. 



8. Cephaelis Ipecacuanha, A. Richard, 1820.
