The buds examined were soaked in 70% alcohol and free-hand sections cut and mounted in balsam. On account of scarcity of material, the buds of several species were not sectioned but dissected on the growing plant. Such are marked with an asterisk (*). As far as possible living material was taken, mostly from native plants. Those species not native were studied from specimens growing in the University Botanic Garden. In a few cases dried specimens were resorted to. About one hundred and twenty-five plants belonging to the following species and varieties were examined. Salix nigra Marsh. S. amygdaloides Anders. S. triandra L. *S. undulata Ehrh. S. lucida Muhl. S. pentandra L. S. fragilis L. S. alba L. S. alba vitellina (L.) Koch. S. babylonica x fragilis. S. babylonica L.
