This is a book on aquatic plants written in accessible language, so that anyone interested in water plants can acquire useful knowledge about them. As far as possible botanical language has been used sparingly, and then only when absolutely necessary. There are nearly half a million aquatic species in existence, and therefore it is impossible even to attempt to cover a small fraction of this in a single volume. Therefore a selection consisting of over 350 commonly known species has been described within, to kindle the interest of the plant enthusiast and give a flavour of this specialised subject area. For ease of identification, the text is accompanied by 150 line drawings and photographs
