Compsonevia myrionematoides S. and G. 



Fig. 1. Six fragments of plants showing the character and position of the 

 gametangia, the basal filaments and the erect sterile filaments. X 125. 



Compsonema fructuosum S. and G. 



Fig. 2. A small part of a frond showing some abnormal developments of 

 gametangia. Two are terminal on lateral branches. Two have developed in 

 one old gametangium. One is terminal on a long pedicel growing up through 

 an empty gametangium. X 2.50. 



Compsonema sporangiifenim S. and G. 



Fig. .3. A few fragments of erect filaments showing unusual terminal game- 

 tangia and terminal zoosporangia. X 125. 



Fig. 4. A group of young gametangia and erect filaments. X 12.5. 



Fig. 5. A fragment of a plant showing zoosporangia in various positions, 

 some sessile on the basal filaments, some sessile and lateral and some terminal 

 on the erect filaments. X 125. 



Figs. 6, 7. Fragments of filaments showing lateral secund branching near 

 the apices. X 125.
