A peculiar form of Xitophvllum has been known among us 

 to occur on various parts of Japan. The plant is found epiphytic 

 on Amphiroa, Corallina, Symphiocladia, Gclidium, or other flabel- 

 late alga;. The principal part of frond is prostrate on the host, 

 frequently extending on or enveloping a larger portion of the 

 latter. The terminal segments of frond arc generally free and 

 often erect, and divided in various ways. The frond gets hold 

 to the host by means of minute rhizoidal processes issued Irom 

 the under surface. In the free segments these processes are also 

 richly found. Cross sections of the middle part of frond show 

 five layers of cuboidal cells, the middle one being composed of 

 colourless large cells and the two on both sides, of chromoplast- 

 containing smaller ones. A surface view of frond shows micros- 

 copical nerves running through the elongate, angulate, epidermal 

 cells. Sori arc found as roundish patches on small ovate seg-
