On Flowers and Insects. 



some of the pollen adhering to the under side of its 

 body. The upper part of the pistil terminates in 

 two branches (fig. 45, sf), each of which bears a little 

 brush of hairs. These hairs serve to brush the pollen 

 out of the tube; while in the tube the two branches 

 are pressed close together, but at a later stage they 

 separate, and thus expose the stigmatic surfaces (fig. 

 45, sf), on which an insect, coming from a younger 

 flower, could hardly fail to deposit some pollen. 

 The two stigmas in the ray florets of this White 

 Daisy have no brush of hairs ; and they would be 

 of no use, as these flowers have no stamens.
