Summary: Common Marsh, Underwater & Floating-leaved Plants of US & Ca
Review: Hotchkiss has provided a practical, easy-to-use guide to identifying underwater and marsh plants to species level. This information is useful to wetland scientists, aquatic biologists, and others who need to accurately identify and characterize submerged plant communities. Line drawings are easy to read and distinctions between common species are clear. Drawbacks: incomplete when it comes to rarer species.

Summary: Has a permanent place on my bookshelf
Review: I've used this book for more than 20 years, starting as college student, and still use it regularly, for myself and as a good overall reference for others with a growing interest in marshes and wetlands. I agree it offers little on rarities, but I've never felt that this was its aim. There are other more specialized texts to help you with these. But for a good guide to take along on a field trip to learn about marshes and their plants, it's ideal.
