Brachxthccium salebrosum Hoffm. Belt Mts. (78); Co- 

 lumbia Falls, Oct. and April (345). Apparently a younger 

 state of this species, growing on earth over stump is (344). 



Brachxthccium acutum Mitt. Columbia Falls, May (385). 



Brachythecium albicans (Neck.) Bry. Eur. Columbia 

 Falls, April (347). 



Brachythecium turgidum (Hartm.) C. Hartman. Near 

 Birch Cr., Blackfeet Ind. Reservation. Leaf-cells somewhat 

 thickened and pitted below. Both stem and branch leaves 

 are minutely serrulate in the slender point (scarcely visible 

 under a magnification of 30 diameters) and the perichaetial 

 leaves have a few coarse teeth at base of subula. Sept. 21, 

 fruiting ! (401). 



Brachythecium rutabulum (L.) Bry. Eur. Columbia Falls, 

 in swamps or very wet places, April (258). 



Brachythecium platycladon C. M. & K. Belt Mts., Two- 

 medicine Lake, Columbia Falls, April. I believe this is dis- 

 tinct from any form of rutabulum. It grows in very soft, 

 loose mats on damp, shady ground, not in water. The leaves 

 on the average are broader, shorter, more spreading and often 

 complanate, the capsule shorter, larger toward the base and 

 lid lower, also distinctly dioicous plants seem to be the rule

Brachythecium Starkei (Brid.) Br. & Sch. Columbia Falls,

Brachythecium vclulinum intricatum (Hedw.) Br. & Sch. 

 Columbia Falls, April. Western plants undoubtedly average 

 somewhat larger than eastern or ordinary European speci- 

 mens. I have found the stem leaves of Montana plants up
