Barbary, and the Levant. (Olive.) 



A small grey evergreen tree, with hoary rigid banches. Leaves lan- 

 ceolate, or ovate-lanceolate, mucronate, short-stalked, green above, 

 hoary on the under side. Racemes short, axillary, erect, very much 

 shorter than the leaves. Corolla white, with broad ovate segments. 

 Fruit the size of a damson, purple, with a nauseous bitter flesh en- 

 closing a sharp-pointed stone. From the pericarp is obtained by 

 pressure the well-known substance called Olive oil ; the medical pro- 

 perties of which are demulcent, emollient and laxative. It enters 

 extensively into the preparation of plasters, liniments, cerates, oint- 

 ments and enemas. As an external application, accompanied by long- 

 continued friction of the skin, it has been found beneficial in preventing 

 the contagious influence of the plague. The bark is bitter and astrin- 

 gent, and has had a great reputation as a substitute for Cinchona, 

 according to De Candolle. It also yields a kind of gum, or rather a 

 gum-like substance, once in repute as a vulnerary; this has been 

 found by Messrs. Paoli and Pelletier to contain a peculiar substance 

 which those chemists have named OlivUe. 



ORNUS. 



Calyx very small, 4-cleft. Corolla divided to the base into 

 linear segments. Pericarp a winged key not dehiscing.

A small tree 20 or 30 feet high, with a close round head. Leaves 

 unequally pinnated, in 3 or 4 pairs ; leaflets stalked, oblong, acute, 

 serrated, very hairy at the base of the midrib on the under side. Pani- 

 cles dense, terminal, nodding. Petals narrow, white, and drooping.

 Manna in the shops, well known as a useful gentle laxative.
