This freshwater alga is fairly common in Japan and is often 

 collected to prepare for food. The plant is thoroughly washed 

 in a clean water and spread on a matting in square sheets of 

 various sizes. When dried in the sun, the fronds adhere one 

 another by their own gelatinous matter and yield bright green 

 sheets which peel off easily from the matting The sheets are 

 baked on fire and eaten with boiled rice to give a flavour to it, 

 or they are cooked in a soup. 



Comparing the Japanese form, which passed under P. japo- 

 nica Yatabe, with reliable specimens of the present species, I 

 can not find any difference which justifies the separation of the 

 former from the latter. 



A specimen of this plant, collected by Mr. T. Marino in 

 Chikugo Prov., Kiushu, is found in the herbarium of the 

 Academy of Science of St. Petersburg, under Monostroma 

 quaternarium Kutz. The determination was by Kjellman. 



Localit}-. In streams on the Pacific side of Honshu and 

 Kiushu. Note that in the streams which run into the Japan 

 Sea the plant is not yet found. 



Distribution. Oregon ; Colorado ; Mexico ; South America.
