SOMERSET RARE PLANTS GROUP www.somersetrareplantsgroup.org.uk 2012 Newsletter Issue No.13 Editor: Caroline Giddens December 2012 This is the last Newsletter compiled and edited by Caroline Giddens. Caroline has done this task each year since our first modest issue in 2000 - a slim 4-page document comprising short accounts of the field meetings. Each year we have increased the content, which has reflected the variety of activities of the Somerset Rare Plants Group. We now include not only more extensive notes of our meetings but also plant notes, new Somerset and vice-county records, surveys that members have undertaken and other botanical news of interest to Somerset botanists. We thank Caroline for all her hard work over the last 12 years.
