Leaves dark green when dry, flaccid, oval-oblong, broader at 

 the middle. On the rocks in Glacier Creek, above the railway 

 bridge at the Glacier Hotel, Selkirk Mountains, B. C. 1885. 



(/?) nigrescens. Kindb. 

 Leaves blackish green when dry, rigid ovate-oblong, broader 

 below the middle. On rocks in the bed of Nanaimo River, be- 

 low the railway bridge, Vancouver Island. Collected 1887. 



Merceya latifolia, Kindbcrg. n. sp. 



Densely caespitose. Plants 1-2 cm. high, brown ferruginous^ 

 below, green at the tips, divided, at the base radiculose. Leaves 

 quite smooth, spathulate-lingulate, obtusate or sub-acute; entire, 

 slightly reflexed at base, plane above, broad bordered with 

 greater, orange-colored cells; basal cells narrow, upper small and 

 round costa percurrent, or scarcely excurrent. Habit of Bar- 

 htilba ruralis. 



The systematic position of this genus is not quite definite. 

 Prof. Boulay unites It to the Weissiese; Schimper considered it 

 allied to Encalypta ; we suppose that it is more nearly related to 

 Barlmla. The allied European Scopelophila ligttlata^ Spruce, 

 {^Merceya ligulata, Sch.) differs in the leaves, smaller, narrow 

 and rounded above, and the abbreviated costa; the capsule is 

 gymnostomous. 



Collected on the upper slopes of -Mount Finlay son, near 

 Coldstream, Vancouver Island, May 1 8th, 1 887, by John 

 Macoun. 



PlIYSCOMITRIUM MEGALOCARPUM, Kindberg, n. sp. {Gym- 



nostouniin mcgalocarptim, Kindb. Mss.) 

 Nearly allied to Physcomitnzim pyriforme ( Gymnostomnin 

 pyriforme, Lindb.) ; leaves longer, more or less acuminate, dis- 

 tinctly yellow-margined ; cells smaller, the upper narrower; 

 capsule larger, subglobose ; Hd conic, without distinct beak ; 

 calyptra unsymmetrical bilobed with long acumen; pedicel long. 



Abundant in meadows in the neighborhood of Victoria, Van- 

 couver Island. Collected May 7, 1S75, and examined by Austin, 

 who concluded it was a large variety of P, pyriforme. Lesque- 

 reux and James make no mention of it. Remarkably fine speci- 

 mens were again collected May 8, 1S87, by John Macoun. 



Bryum angustirete, Kindb. 



Differs from B. pendulum in the leaves narrow, ovate-lanceo-
