Article 1. OLEA Auct. Many Sp. have been 

 improperly united to this Genus, and many real 

 Sp. blended as varieties, the common Olive is 

 the type, all others must be again examined. 

 The nat. family OLEINA of R. Brown of which

 varieties with different shaped. leaves or fruits, 

 are real species, whether primordial or devia-
