Harris : Anomalous anther-structure 



locelli secured by the strong invagination of the lateral wall which 

 is folded in almost to the connective. Here there is an indication 

 of a beginning of the separation of the two locules (figure 2, c). 

 The split soon extends across the connective, leaving the two 

 halves of the anther free for the greater portion of their length. 

 These conclusions are drawn from the examination of sections, 

 and it is quite probable that the two halves become disconnected

lower in the anther in the process of sectioning than they would 

 otherwise. At the same time the sharpness with which they are 

 divided along the median line and the distance to which this sep- 

 aration of the locules extends from the tip indicate a natural 

 longitudinal division. 



As 



the flower, each locule opens by an introrse 



extending for some distance from the tip. The exact form of this 



longitudinal split
