 Bryum froudei, Kindb., Ott. Nat., Vol. V, p. 180. 



Habit of Webera nutans. Agrees with Bryum inclinatum in the synoecious inflo- 

 rescence and the symmetric capsule, etc. ; differs in the leaves being long-acuminate, 

 cells long and narrow, the upper sublinear (nearly as in Webera), costa very long- 

 excurrent, peristomial segments quite free from the teeth, spores smaller, scarcely 0.02 

 mm.; the cilia are wanting. 



Crevices of rocks, St. Paul Island. (J. M. Macoun.) First collected in 1891. 



Bryum brachyneuron, Kindb., Ott. Nat., Vol. V, p. 180. 



Agrees with Byrum 'pendulum in the synoecious inflorescence, the peristomes 

 orange, the segments adhering to the teeth, the apiculate lid and the large spores 

 (about 0.04 mm.); differs in the decurrent leaves, short-ovate, the costa broad, abbre- 

 viate, not excurreut, the sterile shoots bearing globose buds (gemmae), the very much 

 broader peristomial teeth. Stem red, very short, the pedicel about 1 cm. long or 

 shorter, often scarcely emerging above the tufts ; costa of the lowest leaves red, per- 

 current only in the leaves of the shoots and the perichetial ones ; capsule ventricose, 

 short-necked constricted below the mouth. Bryum fallax, Milde., resembling it in 

 habit, is dioecious; the segments are free, the spores smaller. Bryum lacustre differs 

 in not having decurrent leaves, the capsule not being constricted below the mouth, the 

 pedicel longer, the peristome pale, etc.
