As reported in a recent email update, in September 2015, Professor Mark Seaward kindly donated his Herbarium (a collection of pressed plants mounted on good quality paper) to the Sir Joseph Banks Society.
This collection of flowering plants and ferns, assembled over the past half century, comprises about 858 sheets (excluding duplicates) of specimens amassed by numerous collectors over the period 1888-1991, but mainly in the 1950s, 1960s and 1980s. In all, more than 608 taxa (species & varieties) in 287 genera are represented from c. 330 British, c. 203 Irish, 19 Channel Island, c. 302 Foreign & 4 non-localized areas. Mounted specimens in folders are housed in boxes and filed numerically according to the generic and specific numbers provided in Dandy, J.E. (1958, List of British Vascular Plants, London). Most of the British material has been collected from Lincolnshire and Yorkshire, but specimens from 23 other English counties are represented (Cambridgeshire, Cheshire, Cornwall, Cumbria, Devon, Dorset, Durham, Essex, Gloucestershire, Hertfordshire, Huntingdonshire, Lancashire, Leicestershire, Middlesex, Northamptonshire, Nottinghamshire, Rutland, Shropshire, Somerset, Staffordshire, Surrey, Wiltshire & Worcestershire), as well as from five in Wales (Cardigan, Carnarvon, Merioneth, Montgomery & Pembroke), from five in Scotland (Dumfries, Fife, Lothian, Perthshire & Stirlingshire), and from the Channel Islands (Guernsey, Herm & Jersey). There are also specimens from 15 Irish counties (Carlow, Cavan, Clare, Cork, Dublin, Fermanagh, Galway, Kerry, Kilkenny, Leitrim, Mayo, Tipperary, Westmeath, Wexford & Wicklow). In addition, there are specimens from 29 other countries/regions/islands (Africa (NW), Australia, Austria, Bosnia, Bulgaria, Carpathians, Chagos Archipelago, Corsica, Croatia, Crete, Czechoslovakia, France, Germany, Hungary, Israel, Italy, Japan, Liechtenstein, Madeira, Montenegro, Morocco, Poland, Pyrenees, Romania, Sardinia, Serbia, Slovenia, Spain & Switzerland). A catalogue of the contents has been prepared.
