 is emitted,' which takes place by 

 two short clefts of variable extent. 

 The inner surface of the filaments 

 is often prolonged into a kind of ac- 

 cessory collarette applied to the 

 ovary. The ovary is free, superior, 

 formed of five oppositipetalous cells, surmounted by a style with stig-
