This richly illustrated book contains 24 scientific articles on plants and molluscs written by 38 colleagues and former students of Wim Kuijper. The majority of these articles deal with one or a few species found on archaeological excavations, from corncockle via Glycymeris shells to forget-me-nots. A member of staff of the Faculty of Archaeology at Leiden University for 40 years, Wim has supervised students and advised colleagues in the fields of plant and mollusc remains with great enthusiasm and success. They are very grateful for this help and this compilation is the result. The book contains both Dutch and English text. English contributions have a Dutch summary and Dutch articles have an English summary. All captions are in Dutch and English.
