propagation I cannot say; many of the plants in a tuft were so 

 loosely connected and so easily separated that one could doubt 

 their origin in this way, but the connection between the single 

 plants can of course early decay. If we consider Fig. 40 we 

 find, that each of the young plants growing up from the rhizome-

 a, b, c, tops of young plants in different stages of development, in a the 

 cell contents have newly been divided, in I the young cells have swollen, 

 the ring of warty outgrowths showing the first beginning of the filaments 

 in the head, in c the warty outgrowths have grown longer, d, shows a 

 longitudinal section through"^a somewhat older specimen in which the fda- 

 ments have begun to be divided, e, part of fdaments. / and g, young 

 filaments showing the mode of cell division. /( and i, rhizoid-like haptera^ 

 growing out from the filaments, k, chromatophores with pyrenoids and 

 nuclei, (a, b, c, d, e, about 10:1; /, g, h, i, 25:1; /.-, 250:1). 



like rhizoid to the left is separated by a cell wall in the rhizome- 

 like filament from the next young plant, each in this way 

 receiving a piece of the rhizome from which rhizoids grow 

 out downwards. Most probably the young phnnts are easily
