THE BIRCH TRIBE. 



Fine timber trees, or shrubs, referred to 2 genera. Of these, Spreng. 

 syst. assigns 12 species to N. America; 8 to Europe; 2 to Siberia; 2 to 

 S. America and Mexico ; and 1 to Terra del Fuego. In the E. Indies 

 have been discovered 11 forms, viz. 8 of Betula; and 3 of Alnus ; all natives 

 of Nepal. 1 (or perhaps 2) species of Alnus has been found in S. Africa. 

 {Harvey.) 



" Their bark is astringent, and sometimes employed as a febrifuge ; but 

 they are chiefly valued for their importance as ornaments of a landscape. 

 Their vv^ood is often light, and of inferior quality, but that of the Black 

 Birch of N. America is one of the hardest we know." {Lindl.)
