The Phylogeny and Classification of the Ferns. 1973. (Supplement No. 1 to the Botanical Journal of the Linnean Society, Volume 67, 1973). Reprint 1984. illustrated. XIV,284 p. gr8vo. Bound. (ISBN 978-3-87429-218-4)

The book is based on a symposium on The Phylogeny and Classification o fthe Filicopsida held jointly by the British Pteridological Society and the Linnean Society of London in April 1972. The aim of the symposium was to bring together scientists of various disciplines whose research could be employed to simplify various fern phylogenies. The publicationis not, however, merely an account of the symposium, but has been enlarged, especially in the bibliographies, to form a reference book to the cytology, anatomy, palynology, chemistry and gametophyte studies in the Filicopsida. - Contents: Foreword/ List of contributors/ Preface/Symposium programme/ Holttum, R.E., Posing the problems/ Pichi Sermolli,R.E.G., An historical review of the higher classification of the Filicopsida/ Harris, T.M., What use are fossil ferns?/ Bierhorst, D.W.,Non-appendicular fronds in the Filicopsida/ Van Cotthem, W.R.J.,Stomatal types and systematics/ Atkinson, Lenette R., The gametophyteand family relationships/ Walker, T.G., Evidence from cytology in the classification of ferns/ Swain, T. & Cooper-Driver, Gillian: Biochemical systematics in the Filicopsida/ Mickel, J.T., Position of and classification within the Dennstaedtiaceae/ Tryon, R.M. jr. & Tryon,Alice F., Geography, spores and evolutionary relationships in the cheilanthoid ferns/ Sen, U. & Sen, Tuhinsri: Anatomical relationships between the Oleandra and Nephrolepis groups/ Holttum, R.E., Classification of the Thelypteridaceae/ Wood, C.C., Spore morphology in the Thelypteridaceae/ Sledge, W.A., Generic and family boundaries in the Aspidiaceae and Athyriaceae/ Lovis, J.D., A biosystematic approach to phylogenetic problems of the Polypodiaceae/ Wagner, W.H. jr., Some future challenges of fern systematics and phylogeny/ Manton, Irene,Closing address/ Group photograph and key/ Index.
