Flower of the Salvia. 
I. Half a flower, showing the filament /, the swinging anther a b, 
b' a', and the stigma j. 2. Bee entering the flower pushes the anther so 
that it takes the position a'b', No. I, and hits him on the back. 
3. Older flower : stigma touching the bee. 
cut in half, but in the whole flower, one stands on 
each side just within the lip. Now, when the bee 
puts her head into the tube to reach the honey, she 
passes right between these two swinging anthers, and 
knocking against the end b pushes it before her and 
so brings the dust-bag a plump down on her back, 
scattering the dust there ! You can easily try this by 
thrusting a pencil into any Salvia flower, and you will 
see the anther fall. 
You will notice that all this time the bee does not 
touch the sticky stigma which hangs high above her j
