THE MYRTLE TRIBE. 



Trees or shrubs, of 45 genera, amounting to 670 species, the greatest 

 number of which belong to S. America, New Holland and the South Sea 

 Islands and the E. Indies. The latter contain, according to our materials, 

 about 131 forms ; viz. 2 of Melaleuca; 3 of Metrosideros, (Roxb.) ; 1 of 

 Fabricia, (Roxb.); 1 of Bdckea ; 3 of Sonneratia ; 1 of Nelitris ; 1 of 

 Psidium; 1 oi Jossinia? ; 1 oi Myrtus ; 1 of Monoxera ; Wight, (Myr- 

 tus spectabiHs, Bl.) ; 110 of Eagenia, ( Wight, ill. 2, p. 13 ;) — , of Rho- 

 damnia ; 2 of Glaphyria, and 2 of Myrtus ? Wall. Three have been found 

 in Cochin- China, but are nearly unknown ; 14 in Madagascar, Bourbon, 

 Mauritius, and the Sechelles ; 2 in Guinea and Senegal ; 3 in S. Africa, 

 {Harvey) ; and 1 (Myrtus communis, L.) in S. Europe. — Backea frutes- 

 cens, L., a Chinese shrub has been discovered on Mount Ophir, near 

 Malacca, by Dr. Oxley. 



" The pellucid dotting of the leaves and other parts indicates the 

 presence of a fragrant aromatic or pungent volatile oU, which gives the 

 principal quality to the produce of the order." {Lindl.) The properties 

 of the Indian Myrtacese will be adverted to under the diflFerent species.
