Sta. 2, arising from the corolla and included within its tube. 



Ova. free, 2-celled, each cell with l erect ovule. Sty. l. Stig. 2-lobed. 



Fr. either a double berry, or a capsule separable into 2. Sds. 2. 



Genera 5, species 100, ornamental shrubs abounding in tropical India. The essential oil which pervades 

 the order, residing chiefly in the flowers, is exquisitely fragrant. On this account, as well as for their 

 beauty, many of these plants are cultivated.

ORDER CIY. OLEACEJE OLIVES. 



Trees and shrubs, with opposite, simple, sometimes pinnate leaves. 



Fls. perfect (sometimes dioecious). Sepals united at base, persistent. [vation ; rarely 0. 



Cor. Petals 4, united below, sometimes distinct but connected in pairs by the filaments, valvate in aesti- 



Sta. 2. alternate with the petals. Anth. 2-celled, bursting longitudinally. 



Ova. free, 2-celled. Ovules in pairs, pendulous. Style 1 or 0. Stigma entire or bifid. 



Fr. drupaceous, baccate or samara, usually 1-seeded by abortion. 



Sds. Albumen dense, fleshy, abundant, twice as long as the straight embryo. 



Genera 24, species 130, natives of temperate climates. The ash is very abundant in N. America. The 

 Phillyreas and the Syringas are all Oriental. 



Properties. Olive oil is expressed from the pericarp of the olive (Olea Europsea). The bark of this 

 tree, and also of the ash, is bitter, astringent and febrifugal. Manna, a sweet, gentle purgative, is the 

 concrete discharge of several species of the Fraxinus, particularly of the European F. Ornus. The spe- 

 cies of the ash are well known for their useful timber.
