Within the British Isles, Cornwall and the Isles of Scilly have a remarkably rich and varied fern flora, and Ferns, Clubmosses, Quillworts and Horsetails of Cornwall and the Isles of Scilly is the culmination of many years of study of these enigmatic plants by the authors. An invaluable guide to over 70 ferns, clubmosses, quillworts and horsetails, this book covers species (both native and introduced), subspecies, varieties and hybrids. Each account has a short description of the plant where relevant; the distribution in Europe (including the British Isles); and habitats and distribution in Cornwall and the Isles of Scilly. Maps show distribution by a 2 km × 2 km square (tetrad) basis in Cornwall, and at a finer resolution (by six-figure grid references) in the Isles of Scilly. Scanned images of actual specimens are given where these help and colour photographs are included throughout. The introduction covers the various habitats in Cornwall, the climate, soils and geology and the effects of such activities as mining and china clay workings, and the special conditions on the Isles of Scilly.

Many interesting records have been made in the last few years and are continuing to be made. This includes the very recent 2012 finds on the edge of Bodmin Moor: populations of Marsh Clubmoss, a species that has always been extremely rare in Cornwall and is now Nationally Scarce and Endangered, together with Stag's-horn Clubmoss, a species previously considered extinct in the county. Ferns, Clubmosses, Quillworts and Horsetails of Cornwall and the Isles of Scilly will no doubt spark new appreciation and interest in ferns and encourage more people to record this often overlooked group.
