Remarks : Now, by putting Herpochondria in Ceramiacece., the ex- 

 istence of that genus btriinics doubtful and 1 am inclint^l to bring it under 

 Microclo'dc <>!i the -round that the structure of frond, and character- of 

 apical cells, tetraspores, as well as cystocarps are all identical m 

 the latter genus. The structure above stated will be found to be as just 

 same as that described under Mivrochi'H,, yhuuhilow {?). Tin- sli-hm 

 incurved growing ai>ex of shoots terminated by two apical cells is also saun- 

 as it is in the plant just mentioned, in which the terminal cells are also 

 two and are either incurved or parted. The mode of ramification whirl! 

 is dichotomo-alternate and tetraspores which are arranged at the beginning 

 in a subregular order, are also similar, and as so many characters are com- 

 mon to Microcladia, I thiuk it is proper to refer this plant to that genus.

In doing these studies, I have consulted with the conspectus of genera 

 of Ceramiacece given in ' Pflanzenfamilien ' and have known that Carpo- 

 blepharish separated from subfamily Vera mint- chiefly by having verticillately 

 arranged cortical filaments. Fortunately, I have a few specimens of Car- 

 poblepharis flaccida Kutzung in my herbarium and had chance to study 

 the structure of its frond. In cutting a cross-section, there is observed a 

 central axis and, of cells of the intermediate layer, those disposed along the 

 longer axis of the section are larger than the rest ; and surrounding the 

 central axis there are six cells, of which the two placed towards each surface 

 are a little smaller than the cell on each side. In studying the longitudinal 

 sections, there is found six verticillate branches arising from the axis, of 

 which the two standing on the plane parallel to the surface of frond arise 

 from the middle portion of the cell of central axis, while the remaining 

 two, from a place a little above. For the sake of convenience of descrip- 

 tion, I shall call the former the lower branches and the latter, the upper. 

 Cells forming the lower branches are slightly larger than those of the upper, 

 and these larger ones are those stretched between margins, as is seen in a 



All those cells cut off minor ones toward periphery and thus "cortical 

 cells for that portion are formed. Again, the three proximal cells 

 of the upper branch run parallel to the axis and come in contact with 

 those of the series next both above and below. Each of these cuts oft 

 cells towards periphery, which give rise by further divisions into cortical 

 cells for that portion. All the cells are firmly coalesced together and
