 parietal protoplasm. 



From the lowermost cells in the assimi- 

 lating filaments some thin filaments arise 

 (Fig. 88 c) running along and between the 

 central filaments ; they are branched and 

 consist of rather long nearly cylindrical cells

The filaments of the medullary tissue are subcylindric-barrel- 

 shaped ; their diameter reaches a length of about 100 // or more; 

 in the mucilage be- 

 tween these large 

 filaments run many 

 thin ones ; Fig. 89 

 shows a transverse 

 section of the me- 

 dullary tissue in 

 which the large cells 

 and the thin fila- 

 ments are seen, in 

 their respective pos- 

 itions. 



The carpogonial 

 branch is found 

 nearly in the middle 

 of the assimilating 

 filaments (Fig. 88 c). 

 It is placed laterally 

 upon one of the near- 

 ly cylindrical cells 

 found here. It con- 

 sists of three cells 

 and the carpogonium 

 with the triohogyne. 

 It is characterized 

 by being much cur- 

 ved, the outline of 



the whole branch forming nearly a semicircle and its cells seen 

 from the side having nearly a triangular shape ; their diameter
