Book Review - Ferns, Spikemosses, Clubmosses, and Quillworts - Princeton Field Guides

 

     I am quite sure that for most naturalists the vascular plants encompassed by this field guide, collectively known as "pteridophytes," are difficult taxa to deal with. As a consequence they receive short shrift from many otherwise keen observers, and Emily B. Sessa does a masterful job in convincing us that we should put our trepidation aside and jump in with both feet; gleefully even, with the expectation that we will learn and become entranced.

     That has certainly been my reaction to the book.

     The science is impeccable, the narrative superb, the pictures magnificent.

     Ferns, mosses and their allies are all around us, and on every continent, present even on the frigid barrens of Antarctica, so it really does behoove us to to develop a more intimate acquaintance with them.

     This is not to say that getting to know them is easy, but worthwhile things seldom are, and after all who does not relish a challenge - especially one where the rewards are so great.

     The book begins with a definition of ferns, spikemosses, clubmosses and quillworts, followed by a standard "How to use this book" segment. Eleven pages are then devoted to the techniques required to successfully identify the organisms down to the species level.

     A fine glossary follows.

     Most of the rest of the book is dedicated to a species review, grouped by family, and containing a succinct description highlighting all characters needed to clinch the ID, a range map, handily colour-coded, and several pictures.

     The author wades into the minefield of taxonomy and pays due attention to hybrids, polyploids and reticulate relationships - more grist for the intellectual mill.

     A detailed checklist enables the reader to keep track of species seen and their geographic subregions.

     Many suggestions for further reading and reference are provided, including general reference books, scientific papers, and web-based resources.

     This is a very fine treatment of a complex group of plants that command our attention; indeed our affection.

     I commend this book to all who love nature in its glorious and often prolific diversity; be sure to use it well - and often!
