" A very ornamental bush or small tree which will grow in the very driest po- 

 sitions — for instance, in a fissure of a vertical rock. The wood of this plant 

 Is very strong and can be used for making excellent handles for pickaxes and 

 such tools which have to resist heavy wear." {Proschowsky.) 



A small tree which is found along the coast of the Mediterranean Sea, where 

 it forms a bushy thicket. The evergreen, pinnate, shining leaves exhale a 

 strong aromatic odor when bruised. The tree is particularly ornamental when 

 in flower ; the pistillate flowers are purplish green, and the bright purple, very 

 small staminate flowers are clustered in the axils of the leaves. The fruits are 

 the size of lentils and are black when ripe. They are eaten by the natives. The 

 fruits contain an edible, green oil, which is preferred by the Turks to olive oil. 

 In Tunis this oil is largely used for lighting. (Adapted from Bulletin Soci4t6
