PLATE 2. 



Fig. 1. 382. 1. Arthrophycus harlam. (P^g- 5.) 



1 a. A fragment, showing the base of a large stem which diverges into numerous branches. 

 1 6. A similar fragment, showing a second bifurcation above the first. 



Specimens like the above are of rare occurrence. 

 1 c. A fragment of a branch somewhat spirally twisted and flattened. This specimen gives evidence that the 

 plant grew in an erect or a suberect position, and that the pressure from above cau.sed it to assame its 

 present form. The fragment shows also two broken stems with bifurcating branches.
