Dicranum Howellii Ren. & Card. This seems to inter- 

 grade with the preceding and be rather a variety of it. 

 Columbia Falls, Oct. (365). 



Dicranum Bonjcani De Not. Apparently rare in Mon- 

 tana. South Fork Cut-bank Cr. (416). 



Dicranum Bcrgeri Bland. In swampy places. Mac- 

 donald Lake, Columbia Falls, Aug. (195). 



Dicranum undulatum Ehrh. Highwood and Belt Mts., 

 sterile; Columbia Falls, common, April (162). 



Fissidcns bryoides (L.) Hedw. Tenderfoot Cr., Belt Mts., 

 July ; Columbia Falls, Aug. (209). 



Fissidcns adiantoides (L.) Hedw. On old stumps and logs 

 in swamp. Nov. 26, Columbia Falls (238). 



Fissidcns grandifrons Brid. Giant Spring, Great Falls; 

 North Fork Sun River, Columbia Falls (5). 



Octodiceras Julianum (Savi.) Brid. Apparently rare in 

 Montana. Giant Spring, Great Falls (115). 



Ceratodon purpureus (L.) Brid. Common. Grows in 

 rather tall, hemispherical tufts, sterile, on rock, with rather 

 different aspect from the common form on earth (36). 



Disticliium capillaceum (Swartz.) Br. & Sch. Common 



(38). 



Distichium inclinatum (Ehrh.) Br. & Sch. Often growing 

 with the preceding but much rarer. Sun River Canon, 

 Columbia Falls (37). 



Scligcria campy <lopodaK.mdb. (Plate 35.) Tenderfoot Cr., 

 Belt Mts., July, and near Columbia Falls, Oct., on rock 

 partly calcareous. The specimens from the Belt Mts. were 

 never observed to branch but those from Bad-rock Canon 

 occasionally send out a branch from near the base of the 

 stem. This branch from a fertile plant may bear an an- 

 theridial bud, thus the specimen becomes autoicous although 

 usually dioicous ; I have even found a synoicous flower with 

 the long archegonial and the short antheridial bracts mixed 

 in together (131). 



Blindia acuta Br. & Sch. On wet, shaded rock, Nyack, 



G. N. Ry., Aug. (239).
