This is a memorial volume for Albert Ehrman. The contributions of this Gedenkschrift testify to his scholarly excellence in the field of Judaic-Semitic lexicography and etymology, and do full justice to the richness and thought inspiring qualities of his publications. Besides the papers in honour of Ehrman the volume contains four reprints of the Aramaic 'Fucus, Red Lichen', and a full bibliography of the works of Albert Ehrman.

This catalogue, which integrates nearly 35,000 records of benthic marine algae from the Indian Ocean into a taxonomic classification comprising 3,355 specific and infraspecific taxa in 629 genera, will greatly facilitate future work in this region. The bibliography of 4,000 references is the largest list of phycological literature ever published. The extensive taxonomic and nomenclatural notes are of paramount importance.
