In the previous paper (1953), TANAKA reported about the growth peroid and the germination of spores in Digenea simplex (WuPL.) C. AG. The present writers have here ascertained the younger stages during the period of about 36 days or 6 months since the end of the first spore germination. 1) The younger stages of the frond observed cn the 36th day after the spore germination show the following items : the frond is just discernible by the naked eyes, and the distinctions among the disc, axis, ramulus are dubious: the ramulus grows not only from the disc but from the axis: trichome is attached at the top of the ramulus, but soon falls out. 2) In the case of the young frond observed on the 6th month, the distinctions among the disc, axis, ramulus are clearly discernible, while some fronds sprout 2 4 axes from the same single disc. 3) Beyond the period of 6 months the frond reaches the maximum length of 1.5 cm with axes not branching at the top.
