Abstract

THE general conditions for the preparation and growth of sterile cultures of the heterosporous fern Marsilea have already been described1–3. It was shown3 that, with glucose as carbon source, much better growth was obtained in liquid than on agar media. During further work on this subject an unusual phenomenon was observed in the root system of the agar cultures.
