The anthers are shown in the next figure, but on an enlarged 
scale. 
Fig, 25._STAMENS AND ANTHERS, 
The anther cells, instead of being close together, are at the 
two ends of a long connective, which is attached by a sort of 
pivot joint at about one-third of its length to the stalk of the 
stamen. The lower anther cells contain very little pollen, 
sometimes none at all, while the upper ones are fully developed 
as shown in the figure. When the bee thrusts its head into 
the tube, it presses against the lower cells and pushes them 
back; the connectives revolve on their axis, and the upper 
anther cells are brought down on the bee’s back, the hairs of 
which brush off the pollen which the bee carries away, and as 
soon as it meets with an older blossom, in which the pistil is 
fally developed as seen in the next figure, it is evident that

Older Lower, with pistil developed. 
upon entering the tube of this blossom, the pollen already on 
the bee’s back must be rubbed against the stigma, and the 
cross-fertilization be thus effected.
