The way in which bees secure the honey is by 

 enteriog the flower head downwards, clinging to the style 

 in the middle. Xow, 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 shown 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 

 in 11. A bee which has visited Xo. I., and got well 

 dusted with pollen on its underside, now flies to the
