W. albicans var. deflexa, Bull. Torr. Bot. Club, XVII., 273. 



Allied to Webera nutans. The median and comal leaves are longer- 

 attenuate, denticulate sometimes below the middle, narrow-areolate, 

 their costa is thick, canaliculate and excurrent ; the comal ones 

 revolute at the borders ; only the lowest shorter and short-decurrent \ 

 the peristome is pale ; lid low and flat.

(437.) W. subcucullata, C. M. & Kindb. (n. sp.) 



W. gracilis, Canadian Musci, No. 424. 



This species which has the habit of Mielichhoferia nitida, seems to be 

 intermediate between Webera cucullata and Webera pycno-decurrens. It 

 resembles the last in the small compact tufts, the geniculate pedicel 

 and the dioecious inflorescence, the small, (unripe; short-necked 

 capsule, and the mammillate lid ; but the stems are subjulaceous, and the 

 dull green leaves are densely crowded and not decurrent ; the lower 

 leaves are short and subobtuse, nearly as in Webera cucullata but the 

 ar eolation is narrower. 



Crevices of rocks, Mount Queest, Gold Eange, B.C. ; alt. 6,500 feet. 

 July 27th, 1889. .(J. M. Maeoun.') Among debris near perpetual 

 snow on mountains north of Griffin Lake, Gold Eange, B.C. ; alt. 7,000 

 feet. August 8th, 1889. (Maeoun.)
