36 GEOLOGICAL AND NATURAL HISTORY SURVEY OF CANADA. 



(210.) B. cylindrica, Schiinp. ; Lesq. & James, Mosses of K Ame- 

 rica, 125 ; Canadian Musci, No. 81, in part. 



On rocks, Deer Park, Lower Arrow Lake, Columbia Eiver, B.C., 

 June llth, 1890 ; on damp rocks at Spence's Bridge, Yale, and Agassiz, 

 B.C. ; also wet rocks, Cadboro Bay, Vancouver Island. (Macoun.) 



.(211.) B. robustifolia, C. M. & Kindb. (n. sp.) 



Barbula rubiginosa, Canadian Musci, No. 75. 



Very nearly allied to Barbula tortellifolia. Differs in the dark 

 "brown or olive-green color of the whole plant, the leaves being more 

 crowded, shorter with an ovate-oblong base, borders reflexed nearly to 

 the middle at one side, upper cells larger and sub-pellucid, the basal 

 ones hyaline subquadrate, costa thicker and not excurrent, linear and 

 distinct to the apex. Barren. 



Abundant on rocks at Cedar Hill and other localities near Victoria ; 

 ^Iso on rocks on Mount Erskine, Salt Spring Island, Gulf of Georgia, 

 B.C. First collected at Victoria, May 5th, 1875, and then named B. 

 rubiginosa by Austin. (Macoun.) 



<212.) B. tortellifolia, C. M. & Kindb. (n. sp.) 



Barbula cylindrica, Canadian Musci, No. 81, in part. 

 B. flexifolia, Canadian Musci, No. 399. 



This species very much resembles Barbula horridifolia in its habit 

 font is found in a well-fruiting state. It is generally more robust, often 

 4-5 cm. high and finally sometimes quite red. The stem is more 

 divided, the leaves broader, less distinctly decurrent, the comal ones 

 larger and crowded, short-pointed by the excurrent costa ; the 

 perichetial ones suddenly attenuate to a long narrow acumen, but the 

 costa is faintly excurrent. The capsule is large sub-cylindric, reddish 

 doubly longer than the beak ; peristome long, once loosely contorted 

 whitish. Dioecious. 



On wet rocks on the North Arm, Burrard Inlet, B.C. ; on rocks, 

 by the sea, Telegraph Bay, near Victoria, Vancouver Island ; also on 

 rocks by the sea, Vesuvius Bay, Salt Spring Island, Gulf of Georgia, 

 B.C. (Macoun.') 



(213.) B. circinnatula, C. M. & Kindb. (n. sp.) 



Nearly allied to Barbula cylindrica or rather intermediate between 

 Barbula elata and B. virescens. Differs in the upper leaves being green, 

 circinnate-twisted in the dry state, the peristome paler and the annulus 

 simple ; the areolation of the leaves is also more distinct.
