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

 cylindric; pedicel not very long ; calyptra nearly naked. 



On small trees in thickets, Black's Farm, alonj^ the Coquhilla Eiver, 

 near New Westminster Junction, B. C, April 26th, 1889. {Macouni) 



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

 TJ. 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 sublin'ear, 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 Z7. 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 Eiver, Kent Co., N.B. (Fowler's Gat.) On rocks 

 at Truro, N.S. ; and at Madeline Eiver, Gasp^ Co., Que. ; quite com- 

 mon on rocks along the north shore of Lake Sapei'ior, especially 

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

 Lake Superior. (Drummond.) Pictou, IST.S. (McKay.) Lake , 

 Huron. (i)r. Todd.) British America. (Brummond, No. 153), 

 with TJ. 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 Drummond's ticket may throw 

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

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

 Eiver). 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. & James, 

 Bay V. crispa var. minor. I have never observed a species of Ulota that
