TITE rrCACEE OF JAPAN. 151 



Our specimen is sterile, but very well accords with the 

 descriptions of this species. The leaves in the upper portions of 

 the frond exhibit some monstrosity. The terminal parts of the 

 leaves are swollen — the remaining parts undergoing no modifica- 

 tion — to an obovate vesicle with the narrow end tapering downwards 

 to become confluent with the rib. The accompanying figure 

 (Pi. XVII, fig. 1) will explain much better than a description.

Description of the species. The present species has remark- 

 ably unique characters and is readily distinguished from others. 

 Although a fertile specimen has not yet been found, I do not 

 hesitate to give a new specific position to the plant. The root is 

 disc-shaped while yet very young, but soon spreads horizontally, 

 sending out a number of erect stems multicipitally from the 

 upper surface. The stems of the decayed fronds are cleared 

 from their bases, leaving knob-like protuberances on the prostrate
