collected at Ogasawara-jimu, which have basal segments 

 "united to each other by hair-like roots emitted from epi- 

 dermal cells. From structure of the frond and its habit I 

 think the Ogasawara-specimens to be young fronds of the 

 present plant ; and if this judgement does not fail the basal 

 portion of the present plant should be said to be the in- 

 tricatcd and coalesced mass. In one of specimens from 

 Ryukyu, I found fruits appearing like the same construction 

 as those of Chttoospora fastigata J. Ag. illustrated by Barton 

 in Journ. Linn. Soc. Bot. Vol. 13, p. 507-508 (1897-98) PL 

 28, rig. 4-5. Colour dull yellowish brown irf dried state. 

 Substance membranous in dried frond, and the plant does 

 not adhere to paper in drying.
