The problem with books for identifying pollen is that the darn authors never
seem to have taken pictures of the pollen entering *MY* hives.
 
I finds the best way to identify pollen is to wander about on nice days
smelling the flowers and watching for bees.  When I see a bee gathering
pollen, I check out the color of the pollen pack, then I identify the flower
that she's on.  Voila--I now know the pollen color of one more local flower.
 
This technique also has the advantage of helping me determine honey plant
 bloom cycles.  Only in beekeeping can we wander aimlessly about the fields
(or neighborhood gardens) looking at flowers and legitimately call it work.
 Who wants to read a musty old book, anyway?
