terized by the leaves not falcate-secund, imbricate or homomallous and 

 pointing upward, and the capsule erect and symmetrical or very slightly 

 curved or inclined. It is connected with the type by many intermediate 

 forms. 



Hypnum molle Dicks, var. Schimperianum Sch., Syn. 775 (ed. 2) {H. Schim- 

 peria7ium Lorentz. Moost. 123, 5, 7?^^. c). 



Northwestern Montana: In the vicinity of Lake MacDonald, Flathead 

 Co. (J. M. Holzinger and J. B. Blake, 1898). 



Differs from the type by the longer and more slender stems naked below 

 and by the leaves smaller and with a shorter acumen. 

 DiCRANOWEisiA suBCOMPACTA Card. & Ther. 



In densely tufted cushions. Stems simple or sparingly branched, 

 6-8mm. high, densely foliate. Leaves suberect when wet, crispulate when 

 dry, i-i.5mm. long, oblong-lanceolate, acuminate, subacute or somewhat 

 obtuse, slightly channeled above, nerve attenuate at base, extending to the 

 apex or vanishing a little below. Margin pale below, inflexed above, very 

 entire, cells irregularly quadrate or subrectangular, the lower ones laxer, 

 linear next to the costa, the alar cells distinct, subinflated, fuscous. Other 

 parts unknown. Plate XI. 



Very nearly allied to the European D. coinpacta Sch. from which it dif- 

 fers by the leaves being more narrowly acuminate and generally subacute, 

 the cells of the areolation larger and with thinner walls and chiefly by the 

 costa narrower, attenuate below (16-25// broad; it is 55/^ in D. coinpacta). 

 Along the trail from Holzingers Basin to the Rim. 

 Barbula rufipila Card. & Ther. 



In habit and shape of leaves closely resembling B. aciphylla, differs 

 only in the cells which are twice as large and more distinct "(the upper 

 20-30// in B . rufipila, 12-15// in B . aciphylla) and in the hair point which is 

 often less toothed and sometimes entire. Described from sterile specimen. 



Avalanche Basin ; Holzinger s Basin. 

 Grimmia mollis B. & S. 



This European alpine moss is reported from Greenland, and should be 

 found at intermediate stations in Canada. Base of Sperry Glacier, 

 Grimmia suBSULCATA Limpr. in Rabenh. Cryptog. Fl. Laubm. .757. 



New to North America. Cardot det. Mt. Trilby. 

 Webera carinata (Brid.) {W. cucullata carinata Husnot; Bryum navicu- 

 lar e Card.) 



New to North America. Cardot det. Base of Sperry Glacier. 

 Bryum alpinum L. var. denticulatum Card. & Ther. 



Differs from the typical form in the more slender habit, shorter ovate- 

 acuminate leaves, with scarcely revolute margins, distinctly sinuate-denti- 

 culate above and in the costa vanishing in the apex. 



On the way from Holzinger's Basin to the Rim. 

 Pseudoleskea radicosa (Muell.) Lesq. & James. 



This species was distributed as P. rigescens Lindb : it is the P. atro- 

 virens of European authors. Best det. Holzinger's Basin ; Mt. Trilby.
