Review (by Malcolm Storey)

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.

The first part starts with a key to 14 sections based on vegetative characters. A key to genera for each section follows.

The second part examines each genus, commencing with the Charophytes, followd by the other genera in alphabetical order. In a few cases there is simply a reference to other literature (especially the Plant Crib, 1998). Otherwise the treatment varies from hints on how to distinguish the plants to a full key to the New Forest species.
