The (•apstile is rather shorter than usual in A. '«ir/ttsto^^?«,, otherwise it is much the 

 same.

Vancouver's Island, May, 1875, Macon n. 



Near B. (Ederi (Gtjnn.) Swartz in general appearance, but it is really a very 

 distinct species, as a comparison of the above description witii the following notes will 

 show : — B. (Eile.rL is somcwliat smaller in size and usually of a ferrugineous or fuscous 

 grccii cohir. The stems are very radiculose l)elow; leaves more distant, much shorter, 

 more rigid, strongly recurved whcnmoist, more cariuate, very stronglyrevolute on 

 the margin, still less distinctly papillose above, the cells mostly paralellogramoid ; cap- 

 sule dark colored and strongly ribbed when dry, of a much more solid and opake tex- 

 ture, the cells o\al and somewhat larger; peristomal teeth a little less solid, not so 

 closely ai'ticulated, more suddenly narrowed above the base, not so even on the margin, 

 less fragile, the cilia,' rathej- more perfect; sporangium not free; tiower larger ; peri- 

 cha^tial leaves like the stem-leaves; paraphyses many times more numerous and very 

 consi)icuous.

Peace River, 1871. Jlacotui. 



Readily distinguished from jiU its congeners by its smooth and entire leaves, with 

 a very light costa and with long and extremely narrow cells. — About the size of i>. albi- 

 C((/is and I). Simteri. — The leaf-cells are much narrower than in any other species known 

 to me. 



Dicrankli.a Canadensis (Mitt.) Cynodontimn Canade-nsis, Mitt, in tlie Jour of 

 the Linn. Soc. H, p. 17. — Size of the plant, capsule, peristome, etc., precisely as in Z>. 

 ritria (which probably accounts for its being generally overlooked) The shape and 

 position of the leaves however are (piite different — more as in D. squnrrosd. However, 

 in texture they are nearer to the former species. In D. Canadensis the iiericha?tial leaves 

 are like the stem-leaves in size, jiosition, etc., (semivaginal at the base and recurved- 

 spreading); in D. caria, on the contrary, they are diminished in size, erect, not vagiuaU
