Platygyrium repens ramulis elongatis Bryol. Eur. pl. 256. f. 3. 
Glossy, yellowish green. Branches much larger and longer; 
leaves larger, 1.2X0.4 mm., loosely imbricate, shortly bicostate. 
Type from Skeads' Farm near Ottawa (Macoun). 
ExsiccATr.— Sauter in Breut. Musc. Frond. Exsic. 296; 
Macoun, Can. Musc. 259 in part. 
This variety seems to me to be only a robust loi of a vari- 
able species. It was not considered by Schimper as worthy of 
varietal rank, although he figures the form. I have seen 
Dr. Sauter's type and also Kindberg's and they are without doubt 
the same.  Kindberg's criticisms in Macoun's Catalogue on the 
descriptions and plates of this species are entirely without point. 
The Columbia College specimens of Macoun's no. 259 contained 
no fragment of Platygyrium, but consisted of Pylatsia polyantha. 
Every character that has been supposed to separate this species 
from the genus £xtodon, is possessed by some other member of 
the genus as here constituted, hence, in spite of its unlike appear- 
ance it seems best to place it here.
