This species is closely allied to N. translucens (Pers.) Ag ; 
from which it differs by its smaller size, and especially the much 
smaller oospore (and its locality). 
This species was collected in Sagami, Kodsu, and distributed 
as No. 16 of my Japanese exsiccatae. 
17. Chara gymnopitys A. Br. var. “alpha” A. Br. 
This form, though not exactly corresponding to gymnopitys 
gemdna A. Br., seems to be on the border between that and var. 
{beta) dunuscula A. Br., both from Australia; and as A. Braun 
has left var. “Alpha” blank, it may well be occupied by this 
variety. The stems are about 306 in diam., with small, conical, 
broad-pointed spines ; leaves about 8, stipules 16, the cortex cells 
double, alternately large and small, often with additional, partially 
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.
