W- nutans var, deflexa, Kindb. (n. var.) 



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



Allied to Weber a 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.

(43t.) 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 

 areolation is narrower.

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

 snow on mountains north of Griffin Lake, Gold Eange, B.C. ; alt. Y,00O 

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