Keceptacle and vesicle unknown. 



Remark on affinity. A good number of the specimens of the 

 jiresent jjlant were sent from the Marine Experiment Station of 

 Akita Prefecture. But none of them was either fertile or vesi- 

 culiferous. The exact systematic position can not be ascertained 

 at present. The scale-like leaves, their disposition on the ramules 

 and the general characters of the root, suggest a close affinity 

 to Coccopliora Langsdorfii, from which, however, it may at once 

 be separated by the dotted filiform leaves. 



If referrable to Coccopliora, which is highly probable, the 

 specimens at hand are a vegetative form of the plant, being 

 parallel to the Phyllamphora stage of CoccopJiora Langsdorfii. 

 The lateral ramules with the scale-like leaflets may grow to be 

 the receptaculiferous branches. Further discussion is reserved 

 until we shall have been able to examine a fertile specimen. 



The densely foliferous ramules at the upper portions of tlie 

 stem remind us of the paniculate inflorescence of Imperaia. 

 Hence the specific name.
