THE MOSSES OF ALASKA 335 



Number 1S29 resembles S. latifolium (Lindb.) Philib. by its 

 widely decurrent leaves ; but the latter is a more slender plant, with a 

 thinner costa and leaves hardly or not at all plicate. 

 Brachythecium reflexum pacificum Ren. & Card, in Bot. Centralbl. 



1S90, No. 51. 



(PI. XXIII, fig. 4""^) 



Eurhynchium pacificum Kindb. Eur. and N. Amer. br., p. loi. 



From Juneau (Trelease, 2173) ; Wrangell (Trelease, 1937); Cape 

 Fox (Trelease, 1760a) ; Yakutat Bay (Trelease, 1746, 1758, 1826, 

 2339) ; Disenchantment Bay (Trelease, 2512 ; Brewer and Coe, 634) ; 

 Muir Glacier (Trelease, 1753, 1754, i755» 3469). New to Alaska. 



This variety, which seems to occur along the Pacific Coast from 

 Oregon to Alaska, differs from the type by its stouter aspect, its stem- 

 leaves larger, less triangular, rather ovate-lanceolate, not so abruptly 

 acuminate, and revolute on the borders in the lower part, by its costa 

 thinner and generally vanishing at the base of the acumen, and by its 

 leaf-areolation composed of cells of the same width (about 9 11) but at 

 least twice longer (80-90 /x, instead of 30—35) ; those in the angles 

 longer too, rectangular, seldom quadrate. These characters seem to 

 be constant, and perhaps Mr. Kindberg is right in considering this 

 moss as a species distinct from B. rejlexufn. 



Brachythecium asperrimum Kindb. in Mac. Cat. Can. pL, vi, Musci, 

 p. 300. 

 From Cape Fox (Trelease, 2383). New to Alaska. 



Brachythecium lamprochryseum giganteum Grout in Mem. Torr. 

 Bot. Club, VI, p. iSi. 

 From Atka Island (U. S. S. Albatross Exped., 44). 



Brachythecium plumosum Br. eur., fasc. 52-54, p. 4, pi. 3. 

 From Kodiak (Trelease, 2194). New to Alaska. 



Kindberg has mentioned B. turgidum Hartm. as Alaskan. Four species of 

 the genus Scleropodium, viz : .S. illecebrum Br. eur., 5. cespitosum Br. eur., .S. 

 colfophyllum (Sulliv.) Grout, and 5. krausei (C. Miill) Ren. & Card., have also 

 been recorded from Alaska. We have not seen the first three ; the last is a Hyp- 

 nutn of the section Hygyokypnum. 



Eurhynchium myosuroides Sch. Syn., ed. i, p. 549. 



From Yakutat Bay (Trelease, 1S20) ; Hot Springs (Trelease, 2003 

 in part) ; Unalaska (U. S. S. Albatross Exped., 41). 



Forms approaching var. spiculifcrutti Card., or doubtful between 

 this and var. sub stolon if erum Card.
