Studies in Platanaceae

The present investigation has been executed in the Botanical Laboratory at Utrecht at the suggestion of Professor A. P u 11 e. The intention was to investigate the general life-history, the development and the anatomy of the inflorescence and the flowers and the fertilization of the Platanaceae. Researches on this subject were of great interest because R. von Wettstein in his “Handbuch der systematischen Botanik” has given a leading systematical place to the Platanaceae on account of the very old typus which they seem to represent. The intention of this communication is only to give a brief statement of methods and of the principal results of the investigation; more extensive accounts are contained in my dissertation titled “Onderzoekingen over de Platanaceae”, which has been published in July 1923 and is illustrated by 86 figures.
