alar indistinct ; capsule very small, short-obovate, costate, finally sub- 

 cylindric; pedicel not very lon^ ; calyptra nearly naked. 



On small trees in thickets, Black's Farm, along- the Coquhilla River, 

 near Kew Westminster Junction, B. C, April 26th, 1889. (Macoun.) 



(316.) U. scabrida, Kindb., (n. sp.) 



U. Americana, Canadian Musci, No. 115. 



Tufts large and dense, blackish brown below, green or dark green 

 above. Stem much divided. Leaves crisped when dry, squarrose- 

 falcate when moist, very papillose and opaque, revolute from the base 

 to the middle, comparatively short (as in U. curvifolia), from an 

 enlarged base suddenly sublinear, nearly obtuse; basal cells elongate, 

 alar or marginal distinct and hyaline. Capsule sub-oblong, passing 

 into the long collum ; teeth not reflexed, pale ; calyptra very hairy, 

 lobate ; pedicel long. 



This fine species resembles U. crispa more than U. curvifolia, and is 

 not much allied to the last. The true Vlota curvifolia has the leaves 

 straight and erect-patent when moist, and faintly twisted when dry. 



Abundant on immense boulders between Cathedral Mountain and 

 Mount Stephen three miles below Hector, Eocky Mountains, July 29th, 

 1885 ; also in the same place and on boulders by the torrent at Hector, 

 Aug., 1890. CMacoun.)

On rocks at Bass River, Kent Co., KB. (Fowler's Cat.) On rocks 

 at Truro, N.S. ; and at Madeline River, Gaspd Co., Que. ; quite com- 

 mon on rocks along the north shore of Lake Superior, especially 

 above Michipicotin. (Macoun.) Upon rocks, rarely on trees. 

 Lake Superior. (Drummond.) Pictou, ]I:T.S. (McKay.) Lake 

 Huron. (Dr. Todd.) British America. (Drummond, No. 153), 

 with U. Bruchii and U. crispa. (Mitten.) Lindberg makes out No. 153 

 to be U. crispa var. minor, Lesq. & James which these authors make 

 theirs to be. The following copy of Drumraond's ticket may throw 

 some light on the seeming diflficulty. " On trees in Upper Canada, 

 and upon rocks called Hell's Gate, below Norway House " (on Hay's 

 Elver). It is extremely probable that Drummond' s No. 153 that fell 

 into the hands of Mr. Mitten had a specimen gathered at " Hell's Gate," 

 and which he named U. Americana, the other being as Lesq. «fc James, 

 say U. crispa var. minor. I have never observed a species of Ulota that
