    Research output: Thesisexternal PhD, WU


    <p/>A review and an analysis is given of flowering and sex expression in <em>Acer.</em> The process of sex differentiation was studied in physiological experiments and could be influenced by accelerated flowering and by removal of female.gif flower buds just after bud break. The paper further includes notes on the morphology, mainly of the reproductive organs, and a study of floral morphogenesis. A taxonomic study led to the division of <em>Acer</em> into 15 sections, partly subdivided into 2-3 series. Of these series, two, <em>Ukurunduensia</em> and <em>Wardiana,</em> are described for the first time. A key to the sections and series is added. The evolution of <em>Acer,</em> especially of its flowering and sex expression, and of its morphological characters, is discussed. Notes on sex expression in related genera are included.
