apex this is the stem-node : from it a pseudo-whorl 

 of leaves arises, and, as a lateral bud, the new Chara 

 plant, which at once shows the characteristic alternation 

 of nodes and internodes : observe its position, and 

 successive stages of development. 



Lower down is a second node the root-node, 

 which gives rise to rhizoids ; these may branch and 

 fix the young plant in the mud. 



Further observations may be made on the details of 

 segmentation of the germinating oospore, and the mode 

 of origin of the lateral bud which gives rise to the new 

 Chara plant : but for further information on such points 

 reference must be made to text-books.
