The microscopic anatomy of plants

A review of the main treatises on Plant Microscopic Anatomy and their translations published along the XX century is followed by a discussion on various aspects of the structure in plant cells, methodological questions and terminology.
Problems related to using dry specimens from herbaria for microscopic studies are considered. As an example, a study has been made on a species named in memory of Prof. Dr. Oriol de Bolòs, Delphinium bolosii (BLANCHÉ & MOLERO, 1983).
