Book review: Field Guide to the Flora of the San Gabriel Mountains

Overall, a long-awaited and very useful book with keys to all taxa in the mountain range. The keys include opening ones to families, then, within the families, to genus, species and lower taxa where appropriate. The families, genera and species are arranged alphabetically which is now common and helpful. The taxonomy is apparently based on The Jepson Manual (2012), with a couple of stated updates. There are opening discussions and photos of broad plant communities and photos of a few rare plants.  Otherwise there are no photos or illustrations of any plants in the remaining 300 or so pages. This limits the use of the flora for beginning botanists, who may not know where to look for available illustrations.

Dr. Robert Thorne is acknowledged for decades of work on the flora of the San Gabriels project and then turning it over to Mistretta.  I personally recall a visit with Dr. Thorne at the Herbarium at Rancho Santa Ana Botanic Garden in the mid-1970s and he showed me his card file (pre-computer days) of about 1100 taxa he had documented to that time.  Mistretta’s work includes 1588 taxa.

My personal feelings are that the book would have benefitted from the following additions:

References seem a bit slim for such a large area. While Dick Swinney is given credit for his most extensive collections, his 700+ page, online working list of the flora is not included in the references.

The book is attractively packaged and bound with a slick-surfaced, hard board cover, and at 6.25 x 9.25 inches, it is certainly more portable for field use than The Jepson Manual. Clearly a great deal of work went into compiling a complete listing of all taxa for the mountain range and recording locations from herbarium specimens for each.  The author is to be commended for the years of work this entailed.  The keys will simplify the chore of tracking down an unknown find and the elevational ranges, specific to the San Gabriel’s, will be helpful.  This flora will be very useful to professional botanists, environmental consultants and serious naturalists.
