METHODS OF POLLINATION. 



of the ovary, just within the innermost stamens, and 

 the bee standing on the flower burrows down among 

 the stamens to get in. 



Once more, examine the flower of the common 

 RocUla (Fig. 11). The top of the ovary (which is 

 united to the " cup " as in the last) secretes the honey ; 

 but it is carefully covered over with the broad bases 

 of the five filaments, which make a dome over it.

The way in which bees secure the honey is by 

 entering the tiower head downwards, clinging to the style 

 in the middle. Now, the anthers were at first pressed 

 against the style, the hairs of which " collect " the rough 

 pollen (III.). The anthers then shrivel and fall down, 

 as shov/n in I. The stigmas are not yet ready to 

 receive the pollen ; but as soon as the style is well 

 covered with pollen, the stigmas spread out, as shown

 dusted with pollen on its underside, now flies to the
