This little book is a distinct innovation in the category of wildflower guides, because, while we have had numerous works dealing with the plants of the northeastern United States “and adjacent Canada,” this is among the first to be written for eastern Canada “and the adjacent northeastern United States.” About 400 species of native wild flowers of the region can be identified from the text, and the families for many others can be determined. Four full-color plates illustrate 25 species and there are 298 black-and-white sketches.
