acute or cuspidate, usually all similar in seedling stage, at any rate 

 up to the sixth pair. 



Olea cuspidata belongs to the type with ovate cotyledons, which 

 closely resemble those of Forsythia suspensa. They are remarkable 

 although by no means unique amongst the Phanerogamia in being 

 broader than the first six pairs of leaves. Other instances of this 

 relation of the cotyledons to the primary leaves may be found 

 amongst the Cactese, AsclepiadeaB and Proteaceae. 



Ligustrum japonicum, Thunb. 



Fruit a globose, one- seeded berry. 



Seed obovate or globose, conforming hi shape to the fruit, 

 slightly flattened laterally, 3-4 mm. in diameter ; hilum rather con- 

 spicuous ; testa brownish. 



Endosperm copious, surrounding the embryo, greyish-white or 

 colourless. 



Embryo straight, embedded in the endosperm, colourless ; coty- 

 ledons suborbicular or oblong, obtuse, entire, closely adpressed ; 

 radicle, terete, obtuse, situated with its tip near the hilum. 



Seedling.

 green or almost colourless, 2-3 cm. long. 



Cotyledons broadly oblong, obtuse, entire or minutely emargi-

Stem erect, terete, covered with minute hairs, herbaceous, ulti- 

 mately woody ; 1st internode 6-10 mm. long.

Fruit and Seed. The ovary is superior and free, or more 

 rarely half immersed in the receptacle, consisting of two carpels 

 united by their edges, forming one cell with parietal placentas, 

 or completely uniting to form axile placentas, while in a third 

 type they are connate by their bases only or quite separate, 

 with the placentas on the middle of the ventral suture. The
