Captitalization of genus and species names is inconsistant and has been left as in the original. Hyphenation of some plant names and use of apostrophes in some names is inconsistent and have been left as in the original. Modern spelling of common and Latin names differs in some cases but spelling of names has been left as in the original. Obvious type-setting errors and punctuation have been corrected without note. Other corrections have been noted below.
Plates for this book were used for previous publications by the same authors, one being Canadian Wild Flowers. The plates were used in a different order in this book and as a result some numbers printed on the plates did not match the Table of Contents. Therefore, some plate numbers in the text have been changed to match the Table of Contents. Those changes are noted below.
