THE VIOLET TRIBE. 



Perennial, rarely annual herbs, under-shrubs or shrubs (sometimes climb- 

 ing) or small trees, amounting, under 17 genera, {Lindl.,) according to DC. 

 pr., to 66 species for S. America, Mexico and the W. Indies ; 34 for N. 

 America ; 27 for Europe ; 6 for Siberia ; 6 for N. Holland ; 7 for Madagas- 

 car ; 3 for Senegal ; 2 for Caucasus ; 1 for Altai ; 1 for Persia ; 1 for Arabia ; 

 and 1 for Manilla. S. Africa contains 3 species ; {Harvey) and the E. Indies 

 27, viz. 1 1 from Nepal ; 2 from the Khassya Mountains ; 2 from the Neel- 

 o-herries ; 1 from Kunawur ; 1 from Ceylon ; 2 from Java ; 2 from Penang ; 

 1 from Oude ; 4 from the plains of India ; and 1 from Cochin- China ; 

 19 of them belong to Viola; 3 to lonidium; 3 to Alsodeia; and 1-2 to 

 Pentaloba. 



The roots of nearly all of the section Violese, have an acrid, nause- 

 ous taste, and possess the property of acting as emetics, in a great- 

 er or smaller degree. This is especially the case with Pombalia Ituba, 

 Gin"-., a S. American under-shrub, which with lonidium parviflorura, Vent, 

 is considered to form part of those plants that produce Ipecacuanha. In 

 Europe, Viola odorata, canina, tricolor and arvensis are among the emetic 

 plants, though not acting powerfully enough to be of use in medicine.
