118 GEOLOGICAL AND NATDBAL HISTOET SUEVET OF CANADA. 



77. BRYUM, Dill. 



(454.) B. arctlcum, Bruch & Schimp. ; Lesq, & James, Mosses of 

 N". America, 224. 



On the summit of Mount Albert, Gasp€ Co., Que. ; House Mountain 

 south of Lesser Slave Lake, N.W.T. (Macoun.) Melville Island. 

 (JParry.') Eocky Mountains. (Bawrgeau.) Smith's Sound, between 

 lat. TS"— 82°. {Dr. Hayes.) Clavering Island, Upernivik. {Fl. Gr.} 



(455.) B. erubescens, Kindb. (n.^sp.) 



Stems short, scarcely 1 cm. high, loosely tufted. Leaves of the 

 innovations green and small ; stem-leaves few, red-brown, not decur- 

 rent, ovate-lanceolate acuminate, red-margined, not revolute at the 

 entire borders ; areolation pellucid, decolorate, upper cells narrow- 

 rhomboidal or hexagonal ; costa red, more or less excurrent ; inner 

 perichetial leaves smaller, immarginate, slightly sinuolate above with 

 a percurrent costa. Capsule small, regular, pendent, narrow-oblong, 

 constricted below the mouth ; cilia appendiculate ; lid convex, mammil- 

 late ; pedicel thin, pale red, 2-3 cm. long. Spores extraordmarily 

 large, about 0'03 mm. Dioecious. 



This species having the habit of a Webera {W. acuminata or W- 

 polymorpha), has no affinity to the other Euhrya, found in Canada.- The 

 small reddish leaves and the large spores distinguish it at once. It 

 grows mixed with Amblystegium porphyrhizon. 



On the roots of a turned-up tree close to the discharge of Lake 

 Louise, Eocky Mountains (No. 178). August 18th, 1891. (Macoun.} 



(456.) B. heematophyllum, Kindb. (n. sp.) ; Canadian Musci, 

 No. 555. 



Stems short, about 1 cm. high, loosely tufted or solitary. Leaves 

 small, red, densely crowded, not deeurrent, ovate or ovate-oblong, 

 acute, indistinctly margined, reflexed at the entire borders ; areolation 

 red, nearly uniform and loose ; costa very broad, not, or very short, 

 excuiTent ; perichetial leaves oblong-lanceolate. Capsule (not ripe) 

 regular, pendent, obovate ; lid convex, short-apiculate ; pedicel thin, 

 1-2 cm. long. Spores small. Dioecious. 



This species, probably belonging to the section Eubryum, is peculiar 

 in the thick and broad costa of the red and short leaves. 



On wet rocks in the " Dry Caiion " near the discharge of Devil's 

 Lake, Eocky Mountains (No. 104). August 10th, 1890. {Macoun.) 



No. 164. collected in the same locality seems to belong here, but the 

 single unripe capsule has a mammillate lid.
