(942.) B. pseudo-rigidula, KiDdb. (n. sp.) 



B. rigidula, Canadian Musci, No. 412, in part. 



Agrees with Barbula rigidula in the tufts being fuscescent, the leaves 

 from a short erect base patent or recurved, contorted when dry, long- 

 lanceolate, revolute below, nearly smooth, basal cells pellucid and 

 rectangular, costa brown, nearly filling the narrow acumen ; differs in 

 the leaf-borders not being thickened, the inner perichetial leaves from 

 an oblong base, narrower acuminate with a long excurrent costa ; the 

 peristonie pale and distinctly contorted. 



On earth by a brook at Lytton, B.C., April 17th, 1889. (Macoun.) 

 (See No. 205.) 



(205.) B. spadicea, Mitt. 



On rocks along the Fraser Eiver at Yale, B.C., December 9th, 1872. 

 (Macoun.) 



(207.) B_ brachyphylla, Sulliv. var. angustifolia, C. M. & 

 Kindb. 



Tufts compact sparingly radiculose to the greater part, rusty-red, 

 bright-green at the summit, 1-2 cm. high. Leaves shortly ovate- 

 lanceolate, acute or subobtuse, indistinctly papillose, densely disposed, 

 when dry appressed, borders reflexed nearly all around ; cells small, 

 round-quadrate ; costa broad, reddish and percurrent. Barren. 



(210.) B. cylindrica, Schimp. 

 Ounalaska Island, Behring Sea, 1891. (J. M. Macoun.} 



(943.) B. decursivula, Kindb. (n. sp.) 



Tufts rusty-red with green tops, about 2 cm. high. Stem radiculose 

 below, not rigid ; branches long and filiform. Leaves small, when 

 dry loosely appressed, open when moist, very broad at the base, 

 subovate or ovate-oblong, acute or subobtuse, nearly smooth or faintly 

 papillose at back, loosely disposed, long-decurrent ; borders reflexed 

 nearly all around ; cells pellucid, subquadrate, only the alar elongate ; 

 costa reddish, broad and percurrent. Barren. 



This species, resembling Barbula brachyphylla in the short-leaves, &c., 

 differs in the thinner branches and the leaves smaller, loosely disposed 

 and loug-decurrent. 



On earth, on rocks at Hector, Rocky Mountains, August. 15th, 1890.
