(499.) B. Vancouveriense, Kindb., Bull. Torr. Bot. Club, XVI., 

 95 ; Canadian Musci, No. 457. 



Differs from B. ccespiticium in the leaves being longer acuminate, at 

 the base red, and reflexed only below the middle ; cells small, upper 

 very narrow ; costa very thick, excurrent in most of the leaves ; capsule 

 not pendent and not constricted below the mouth, lid deplanate ; 

 spores larger, about 0.015 mm, ; stem indistinct with gemmiform 

 innovations ; pedicel very long, 4-5 cm. 



On wet slopes of Mount Finlayson at Goldstream, Vancouver Island, 

 June 28th, 188*7. (Macoun.) 



(500.) B. microglobum, C. M. & Kindb. (n. sp.) 



Tufts compact, green, radiculose below, small and about 1 cm. high : 

 branches very short, bearing small buds. Leaves narrow-margined, 

 subentire : stem-leaves ovate-oblong and short-acuminate, faintly 

 revolute at the borders, branch-leaves ovate-acute and not revolute ; 

 upper cells short except the narrow marginal ones ; costa more or less 

 short-excurrent. Capsule small, inclined, pale, globose-pyriform 

 small-mouthed ; peristome perfect ; teeth pale ; cilia short but appen- 

 diculate ; lid convex with a conical mammilla ; pedicel arcuate at apex, 

 about 3 cm. long. Dioecious. 



This species has the habit of Bryum Warneum, also in the shape of 

 the capsule, but it is a true Euhryum with appendiculate cilia. 



On earth, near London, Ont. 1889. (J. Dearness.} 



(501.) B. oligochloron, C. M. & Kindb. (n. sp., ad interim) ; 

 Canadian Musci, No. 554. 



This species is still doubtful, being only found in a barren state. It 

 is peculiar in the upper leaf-cells being very narrow (as in the section 

 Anobryum), the leaves are ovate-lanceolate, long-acuminate, nearly 

 hyaline and the costa long-excurrent. 



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

 Musci. No. 519. 



Tufts compact, olive green, very radiculose to the innovations. 



' Stems about 2-3 cm. high. Leaves appressed when dry, concave, 



obtuse, the lower oblong, the upper ovate, forming small buds, 



chlorophyllose and not yellow nor hyaline, rarely reddish ; borders 



revolute and narrow-marginate nearly all around ; upper cells wide ;
