One of the botanists first to grow fern gametophytes from spores whicch were sown on moist clay was Farlow (1874), a student of the famous botanist, DeBary, professor of Botany at the University of Strassburg in Germany. Farlow sowed the spores of Ptteris cretica var. albo-lineata on moist clay placed into small flower pots. Watering was accomplished from the top. There was no sterilization of the culture medium. The gametophytes of this fern were also grown under the same conditions by DeBary (1878). Steil (1919a) grew the prothalli of Ptteris sulcata and Ptteris cretica var. albo-lineata in the same manner as Farlow and DeBary and observed that those of the former were somewhat larger.
