diodes C. Muell. & Kindb. Macoun, Cat. Can. Pl. 6: 194, make it 
almost certain that the two are identical. Although Prof. Macoun 
assures me that the specimens sent are identical with Kindberg's 
types, the plant from New Brunswick is not the same as that 
from British Columbia which appears to be B. erythrorrhizon. 
31a. BRACHYTHECIUM ERYTHRORRHIZON THEDENII (Br. & Sch.) 
Lindb. Musc. Scand. 36. 1879. 
Brachythecium Thedenii Br. & Sch. Bryol. Eur. fasc. 52—54. 
PL7 1253. 
Stems 5—10 cm. long, slender and creeping, often stoloniferous; 
branching regularly pinnate ; branch leaves long filiform-acumin- 
ate ; perichaetial leaves very long filiform-acuminate. Seta dis- 
tantly but distinctly papillose. 
Errol Dam, Androscoggin River, N. H. (James). 
The variety is one of the rarest of mosses, found in Europe. 
only in Finland and Sweden. 
James’ plant has been carefully compared with authentic 
European specimens and differs chiefly in the larger leaves which 
approach the typical form. The slightly scabrous seta is a charac- 
ter not heretofore noted, but it is quite conspicuous in specimens 
from Sweden which were identified by Schimper himself. 
Schimper’s figure exaggerates the serration of the perichaetial 
leaves.

irregularly divided, creeping, subpinnately branching, sparsely 
radiculose ; branches 3-6 mm. long, ascending, terete-foliate ;
