shape when seen from above (Fig. 394^4), more rectangular in 

 transverse section (Fig. 394 B). 



On the inner side of the wall we find the vertical filaments 

 (Fig. 394 5, D). These are often in quite close connection with 

 the wall-cells, sometimes even somewhat immersed in their thick 

 membrane (Fig. 394 C}. The filaments run from the apex of the 

 branches to the bottom and pass through the diaphragms (Fig. 

 394 A, B). The cells of the filaments are about 16 ^ thick and

about ten times as long. They bear one, or sometimes, two oppo- 

 site gland-cells placed about the middle of the cell. The glands 

 are nearly spherical or somewhat ovate (Fig. 394 C). As a rule 

 the filaments are not ramified, but once a side-branch was found 

 connecting the filament with one of the adjacent filaments. 



Among the larger wall-cells some smaller ones, rather regularly 

 distributed, are generally present (Fig. 394 E) ; like the large cells 

 the small ones, too, are connected by means of pores with the
