(222.) B. aciphylla, Bruch & Schimp. ; Canadian Musci, No. 479. 



On rocks, Mount Queest, Gold Eange, B.C. (J. M. Macoun.) On 

 rocks, mountains north of GriflSn Lake, Gold Eange, B.C. ; diy rocks 

 at Hector, Eocky Mountains, and in Eoger's Pass, Selkirk Mountains,

(223.) B. megalocarpa, Kindb. Bull. Torr. Bot. Club, XVI. 92 ; 

 Canadian Musci, No. 79. 



Allied to B. ruralis, but differs in the capsule being very much longer 

 and cylindrical, at least twice the length of the conic operculum, the 

 peristome shorter than the tubulose base and calyptra vei-y much 

 prolonged below the capsule, the middle leaves more distant, the upper 

 leaves subacute not emarginate or rounded at the apex, and rather 

 acute ; the hair-point is red at the base, and the leaf-base narrowly 

 or not margined, with pale-yellow cells. 



On rocks. Cypress Hills, Alberta ; common on rocks at Eevel- 

 stoke on the Columbia Eiver, at Deer Park, Lower Aitow Lake, 

 and Sproat at Pass Creek ; on rocks at Sicamous and Yale, B.C. ; 

 very common on rocks at Victoria, Comox and other places on Van- 

 couver Island. (Macoun.) It exists also as a variety with a smaller 

 capsule. 



(224.) B. laevipila, Bruch & Schimp. ; Lesq. & James, Mosses of 

 N. America, 132. 



Vancouver Island. (Lyall.) May this not be B. lato-excisa, C. M. 

 & Kindb. ? (Macoun.) 



(225.) B. brachyangia, C. M. & Kindb. (n. sp.) 



Dioecious. Plants brown-ferruginous, 2-3 cm. high. Leaves small, 

 the upper close, curved, short ovate-oblong, obtuse or subacute, the 

 upper part scarcely longer than the sheathing base ; margins slightly 

 recurved in the middle ; broad cells hyaline, nearly uniform ; costa 

 rough at back ; hairpoint long, denticulate, the greater part pale red. 

 Capsule small and short, oblong-cylindric, sub-symmetric ; pedicel red 

 1.5-2 cm. long. 



This species is very distinct from Barbula ruralis in the short, 

 nearly flat leaves, the hyaline leaf-base, and the small capsule. 



On rocks along Becscie Eiver, Anticosti, September 3i'd, 1883. Has 

 been included in B. ruralis. (Macoun.)
