This book could have been a gem for people interested in botany and healing plants, but it does not manage to fill this void. The text is not read by a professional botanist (I assume) and incorrect or dubious facts are common. Furthermore, the text is filled with typos and misspellings that could easily have been caught in a simple spell-checking program. The figures are from older literature and are not well reproduced. The aim with this book, to explain botany in a day, is highly recommendable, but I cannot recommend this book in its present shape and quality-level. A completely corrected, re-formatted, and revised edition of this book is needed. For people interested in the plant families of North America I instead recommend the high-quality work of Zomlefer: Guide to Flowering Plant Families.
