A journey through diatom taxonomy. The enduring legacy of Luc Ector. 2023. (Nova Hedwigia, 171). illus. 421 p. gr8vo. Paper bd.

This volume honours Luc Ector as a diatom scientist with 17 contributions, discussing one of Luc's favorite passions. diatom research. Luc was an inspiring mentor motivating many young (and not so young) colleagues worldwide. This is reflected in the subject of many contributions in this volume. A new genus. Lureciorea gen. nov. (Tudesque et al.),
and numerous new species such as Pinnularia ectorii sp. nov. (Potatova et al.) and Rimonemis ectorii sp. nov. (Marquardt et al.), are named after him.

This Memorial volume includes important revisions and additions to our current knowledge of several freshwater diatom genera (e.g. Abarca et al.). Luc was a keen diatom taxonomist and ecologist who fully understood the value and importance of historic diatom material as a tool for our modern understanding of diatom species. Several contribu-tions in this Memorial volume such as those on Stauroneis actia (Wadmare et al.), Brachysira
vitrea (Van de Vijveret al.) of Frustulia saxonica (Jüttner et al.). start with the
analysis of historic type material to disentangle difficult and confusing complexes.
