developed cells, so that sections show about 20 cortex tubes; 
bracts at the leaf-nodes equally developed. all around, slender, 
long, acuminate-pointed, about 60 in diam. The oogonia seem to 
be distinctly stipitate, the oospores average 560 long by 365 to 390 
broad, with 8 (10-11) striae. The coronula is short, broad and 
square-shaped. Antheridia are rather rarely found, 293 in diam.; 
when present, conjoined. 
This species was collected in Mikawa, Tennu pond, and dis- 
tributed as No. 10 of my Japanese exsiccatae. 
No. 18, same species and variety as the last, collected in To- 
kio, Shinbashi pond, and distributed as No. 11 of my exsiccatae 
Japonicae. Nos. 19, 20 and 21, Nitella pulchella Allen, collected 
respectively in Chikubushima pond, Mikawa Tennu pond, and 
Tokio Shinbashi pond, and distributed as Nos. 13 and 14 in my 
exsiccatae Japonicae. 
As a matter of record it may be well to add that the following 
list of Exsiccatae Japonicae has been distributed as far as speci- 
mens would allow; of WV. sudblucens Allen only fourteen speci- 
mens could be sent out.

There are doubts whether this is a variety of 7radescantia Vir- 
ginica L. or should have specific rank. Forms are found which 
apparently connect the extremes and make it difficult to draw the
