Glamorgan has a rich and diverse flora with over 80% of the vascular plant flora of Wales being recorded in the county. This is the first account for 86 years of the flora of the old county of Glamorgan and the first to treat fully its lower plants. It draws together information on the ecology, abundance and distribution of higher plants, mosses, liverworts and lichens that has, up to now, been largely inaccessible. Maps are provided for all but the rarest of plants and attention is drawn to notable sites worthy of conservation. A novel feature is the inclusion of details of floral biology, including insect visitors, for many species. The flora, as well as being of interest to the naturalist, is of considerable value to conservation organisations and local authorities in formulating conservation strategies and offering advice on all matters concerning the wild and naturalised flora of Glamorgan. This book is a digital reprint of ISBN 0-11-310046-9 (1994).
