I purcased this book last year and am very please with it. It includes all 1,564 herbaceous species recorded in Indiana. It does not iclude grasses, sedges or rushes. There are 640 photographs with at lease one representing each species and drawings of individual species.
Each entry includes scientific name, common name, habitats, general distribution in the state, months blooming, size of plant and a brief description. Species that are introduced to the state or are on Indiana's Endangered, Threatened, and Rare List are marked with a notation about their status.
The book is easy to navigate and it is complete. There are enough photographs included so that you can identify what you have. The illustrations and descriptions easily aid in narrowing down the individual species that you are looking for. I have been able to identify everything that I have looked up using this book. It even includes water plants, bog plants and native orchids.
I love this book and highly recommend it if you have an interest in identifying native plants in Indiana or the Great Lakes Region.
