114 GEOLOGICAL AND NATURAL HISTORY SURVEY OF CANADA. 



(438.) W. pycno-decurrens, C. M. & Kindb. (n; sp.) 



Tufts dense, glossy bright green, 1-1.5 cm. high. Fertile stem 0.3- 

 0.5 cm. high. Leaves small, acute, the lower ovate-oblong, crowded 

 but short-decurrent, the comal very much longer, sublanceolate, 

 revolute at the borders for the greater part, denticulate above, the 

 inner perichetial leaves very much shorter, looser areolate ; costa not 

 excurrent. Capsule obovate, red-brown, distinctly short-necked, 

 annulate, orange -margined at the mouth ; cilia sometimes appendi- 

 culate, inner membrane broad, teeth finally dark yellow ; lid convex, 

 orange-margined, mammillate ; pedicel geniculateat the middle ; spores 

 brown, small, about 0.0 1 mm. Dioecious. This species resembles 

 Webera commutata or rather Webera Lescurii, but seems to be quite 

 distinct. 



On earth amongst rocks, near perpetual snow on the Gold Eange, 

 north of Griffin Lake, B.C. ; alt. 7,000 feet. August 10th. 1889. 

 ( Macoun.} 



(439.) W. microcaulon, C. M. & Kindb. (n. sp.) 



Resembling a small form of Webera polymorpha in the very short 

 (about 3 mm. long) stem and the leaves acute, agglomerate in small 

 buds. Differs principally in the dioecious inflorescence and the very 

 large spores, unripe about 0.03 mm. The capsules (not ripe) are short- 

 obovate, annulate, with a short neck and a low mammillate lid, the 

 pedicel straight, arcuate at the apex, 1 1.5 cm. long, the comal leaves 

 scarcely revolute at the borders, the inner perichetial much shorter. 

 The tufts are very compact; the leaves green or finally blackish. 



On Digge's Island, Hudson Strait. August, 1884. (E. Bell} 



(440.) W. micro-denticulata, C.M.& Kindb. (n. sp.) 



Tufts dense, glossy green, about 3 cm. high. Leaves small, loose 

 when dry open-erect, decurrent, short, ovate-oblong, nearly entire, 

 more widely areolate with a red and not percurrent costa, the comal 

 ones longer, lanceolate, acute or sub-obtuse, narrow-areolate, revolute at 

 the borders nearly all around, faintly denticulate above, costa pale and 

 sub-percurrent. Capsules small (not ripe) obovate, short-necked ; lid 

 low mammillate. Dioecious. 



Probably allied to Webera commutata, Schimp., but differing princi- 

 pally in the distincter decurrent, loosely disposed leaves. 



Close to perpetual snow on the Gold JRange, north of Griffin Lake, 

 B.C. ; alt. 7,000 feet. August 7th, 1889. (Macoun).
