P.D. Moore & J.A. Webb  book  Pollen Analysis
Rex Sawyer, book  Honey Identification 

will get you started. 

the techniques have limitations, some pollen is over represented or under represented due to its 
morphology or stickiness, etc. a correction factor can be employed. 

think of it as a tool in addition to other information you can collect about the honey, like color, 
flavor, time of season collected, and conductivity. 

here's an informative link as well

as with beekeeping in general it is a continual learning process where you become more or less 
certain of the accuracy of your analysis as time goes on.
