1. Germination of the Seeds on Pot-Plants. 
were laid on the roots of several pot-plants. 
The experiments were made in July and the germination took 
place within two weeks. The plants used comprised several 
species of Phanerogams and Cryptogams, two pots being prepared 
for each. 
a. Pteridophytes: Selaginella involvens Spring. (Iwahiba) and 
Aspidium rhomhoideum Wall. (Kanawarabi) have rather weakly 
developed roots. After two weeks some of the seeds laid on them 
were seen to have produced a few globular cells outside the testa 
but no further development took place even after four weeks 
or more. 
b. Gymnosperms: Cryptomeria japonica Don. (Sugi) and Thu- 
jopsis dolabmta S. et Z. (Asunaro) were used. Although the roots 
are not very vigorously developed, yet a few of the seeds pro¬ 
duced globular cells. Further development remained uncertain. 
c. Monocotyledons: Keeping in mind that Aeginetia grows in 
the field exclusively on plants of this group I have used for my 
purpose several species from various families, comprising also the 
well-known hosts for controD). 
Juncaceae. 
Luzida campestris De. var. capitata Miq. (Suzumenohie). 
Cyperaceae. 
Carex japonica Thunb. var. chlorostachys (Don.) Kük.

of roots.

not vigorous.
