126 GEOLOGICAL AND NATURAL HISTORY SURVEY OP CANADA. 



rather nodose ; annulus broad ; lid nearly flat and apiculate ; pedicel 

 red, flexuous, about 2-5 cm. long ; spores small, about 0.018 mm. 

 Dioecious. 



This remarkable species is a true Bubryum, although the pei'istomial 

 cilia are not distinctly, or only at the base, appendiculate. It resembles 

 Bryum alpinum in the color of the capsule, but is very different in the 

 shorter, margined leaves and their wider ai'eolation, the tomentose 

 tufts, &c. 



On damp rocks on the mountain between Pass Creek and the 

 Columbia River above Sproat, June 19th, 1890. (Macoun.) 



(491.) B. pygmseo-alpinum, C. & M. Kindb. (n. sp.) 



Tufts dense and small, about 1 or 1.5 cm. high. Stem sparingly 

 radiculose to the buds. Leaves small, olive-green or finally reddish, 

 flaccid, not glossy, laxly areolate, hyaline ; the uppermost close, the 

 other loosely disposed, not decurrent, very much smaller, all subovate 

 or oval obtuse, the uppermost sometimes subacute ; borders not 

 margined nor revolute ; upper cells short-rhomboidal ; costa broad, 

 pui-plish, percurrent or in the uppermost leaves slightly excurrent. 

 Barren. 



This species is probably allied to Bryum calophyllum or to Bryum 

 obtusifolium, Lindb. On wet rocks, summit of Mount Arrowsmith, Yan- 

 couver Island, alt. 5,700 feet, July 17th, 1887. (^Macoun.) ■ 



(492.) B. percurrenti nerve, Kindb. 



B.percumcentinerve, Kindb., Bull. Torr. Bot. Club. XVII., 274 ; Canadian 

 Musci, No. 505. 



Tufts compact, dull green above, decolorate below, about 2 cm. high. 

 Leaves, when dry, appressed and corrugate, when moistened sub- 

 patent, crowded and slightly decurrent, ovate obtusate (only the upper- 

 most ovate-oblong and subacute), narrow-margined and revolute at the 

 entire borders to the greater part ; areolation pellucid, upper cells 

 wide, sub-rhomboidal ; costa l-ed and percurrent, in] the uppermost 

 leaves pale. 



Allied to Bryum MuehlenhecHi, but differing principally in the color 

 of the plant, the leaves thinner, broader and shorter, at the apex 

 patent or sometimes reflexed, not cucullate. 



On dripping rocks on the face of a small waterfall in a brook just 

 west of the ferry at Kamloops, B.C., June 18th, 1889. {Mdcoun.) 



(493.) B. miniatum, Lesq.; Lesq. & James, Mosses of N. America, 

 233. 



On wet rocks on Sproat Mountain, Columbia Elver, B.C. {Macoun.')
