dentiform, not contiguous even in the bud. The petals are the same 

 in number, alternate, much longer and valvate ; they are generally

stamens, each formed of a free filament and an introrse, bilocular 

 anther, dehiscing by two longitudinal clefts.^ The inferior ovary is 

 surmounted by a style, the base of which is surrounded by an epigy- 

 nous disk, often thick, entire, or more or 

 less lobed. The stigmatiferous summit of ^«^'««^« ^<^'- 



the style is truncate or capitate, entire or • 



nearly so. The ovary contains two, some- 

 times three, alternipetalous ^ cells. In the 

 internal angle of each is a placenta sup- 

 porting a descending, anatropous ovule 

 with micropyle primarily directed upwards 

 and inwards.^ The fruit is a drupe, the 

 summit of which bears the scar of the 

 perianth. The putamen, hard and thick,* Fig. 48. Diagram.

each a descending seed, the coats ^ covering a fleshy albumen and an 

 axile embryo, with superior cylindrical radicle and foliaceous coty-

 finally brings the micropyle on the side. It
