Material from enjoyed a good year with thanks due to all a wide range of species was available but the who had led the various excursions and emphasis was on identifying those that are meetings which were reported in the commonly planted and found naturalised in Newsletter now being distributed. We were the wild. Help was given with pleased to welcome Emma Koblizek from understanding the botanical terms used in the SERC and she was asked to convey our key. The features used in the key are, as thanks to the Record Centre for their help expected, vegetative but it is useful to use with funding for a further supply of cone features for confirmation of Recording Cards, ten hand lenses and the identification so these were also available. In promise of a grapnel for help with the study addition to the species used for identification, of water plants. She also offered to look into material was available from similar species the possibility of MapMate training sessions for comparison. It is hoped the attendees if members required these.
