Northern Bee Books published this facsimile edition of the original book published in 1981. Rex Sawyer wrote the book for the observation and identification of the many varied forms of pollen grains, and for the students, naturalists, beekeepers, allergists and others who need a practical guide for pollen identification. The identifying features of the main pollen types found in the UK are described, forming a key by which they may be recognised. The set of punched cards referred to in the preface has not been reprinted this is now replaced by the CD Pollen identification for beekeepers.
