Field Guide to the Identification of Difficult Aquatic Plants of the New Forest
A field guide to aquatic and some marginal/wet mud plants, including aliens, recorded from the New Forest. The coverage is wide but more detail is given for the "difficult" groups. Although restricted to the New Forest, that area is so rich, that most species found in the south of England are covered.
