This book is not a grass identification book, nor was it intended to be such. It is a guide to the terminology of grass, sedge and rush identification. There are many specific terms used only in the technical description of the grasses, sedges and rushes. This book is a clear guide with excellent diagrams to those terms.To properly identify the grasses, sedges and rushes one needs to turn to the excellent manuals by Hitchcock or Chase. If one is going to use the keys in those books, one needs to know the terms defined in this book. As such it is an important addition to the technical literature on grasses, sedges and rushes.
