21. FissiDENS BusHii, Card, et Ther. 



Owen Sound, Ont., 6th Sept., 1890. New to Canada. 



22. FiSSIDENS RUFULUS, LiNDB. 



On rocks b}' a small waterfall in a brook near the Biological 

 Station, Departure Bay, Vancouver Island, Juh^ 3rd, 1908. 

 New to Canada. 



23. FiSSIDENS (Conomitrium) Julianus (Savi), var. ameri- 



CANUS. 



Leaves tapering to an acute, often subulate acumen. 

 Ontario, Hastings Co., Canadian Musci, n. 54 ("Conomi- 

 trium Hallianum," not so, named by me). 



24. Tetraplodon urceolatus (Brid.) Bruch. & Schimp. 



* t. submnioides, new subspecies. 



Capsule small rufescent, scarcely reaching above the tufts; 

 its neck scarcely longer; annulus none; pedicel thick yellowish, 

 about 6-8 mm. long, not exserted. Leaves entire oval-oblong, 

 often long-acuminate; costa strong, excurrent in a long point; 

 as in T. mnioides. Tufts somewhat lax. 



In the true European T. urceolatus the leaves are oval and 

 obtusate, abruptly narrowed to a shortish point; costa not 

 distinctly percurrent, capsule blackish-brown; pedicel nearly in 

 its whole length exserted above the very compact tufts. 



Although the habit of the present plant is very much 

 different from European specimens, the characters are scarcely 

 sufficient to distinguish it as a proper species. It needs also 

 further observation. 



Collected in Labrador in 1891 by the late Rev. A. C. 

 Waghorne. 



25. Tetraplodon mnioides (L. fil.) Br. & Sch * Breweri 



(Hedw.) 



It seems to be a subspecies of T. mnioides; its leaves are 

 narrower with a very long-excurrent costa. The tufts are not 

 always "loose" (Limpr.) 



Collected on Hunker Creek, Yukon (No. 141), barren and 

 loosely tufted; also (No. 143) fruiting and densely tufted; both 

 in July, 1902. Coll. John Macoun.
