tending from Alaska to California, and eastward to the Belt Moimtains of Mon- 

 tana, but not yet found fruiting. The finest specimens come from the vicinity of 

 Mt. Rainier, those of J. A. Allen's having stems up to 20 cm. long. 1 incline to 

 think it will stand as a species quite distinct from H. niolle. In general appear- 

 ance it more resembles dilaiatum, but is distinct from both these species in hav- 

 ing no central strand to the stem. H. dilatatuni also has a more rounded leaf, 

 with a distinct conve.x cluster of alar cells not found in Besfii, while this last is a 

 stouter plant than moile, with stiff, wiry stems, rough below with tlie broken-off 

 bases of the secund leaves. 



tfON LiriNOBIUM BESTII Ren. & Bryhn, 



Bv J. M. HOLZINGER. 



In The Bryologist of January, 1901, the writer published a brief notice 

 regarding this moss, promising there a more detailed description, some figures 

 and explanations that would do justice to all concerned. Simultaneously with 

 this note there appeared from the pen of M. F. Renauld a discussion and de- 

 scription of this plant and related European forms in the Bulletinf de L'Acad^mie 

 Internationale de G^ographie Botanique, January i, 1901; also in Revue Bryo- 

 logique of the same date. It was the knowledge that these articles were to 

 appear which seemed to justify the brevity of my own note. It has seemed best 

 for various reasons to translate M. Renauld's more full note from the Bulletin 

 above referred to. The accompanying figures were drawn by M. Renauld, and 

 are here published with his consent. 



" Hypnum (Limnobium) molle Dicks. Subspecies *H. Bestii Ren. et Bryhn. 

 Cushions soft pale olive-green. Stem stout, firm, 6 — 8 cm. long, at the base 

 generally stripped of leaves, divided above into several erect branches. Leaves 

 distant, everywhere spreading, sometimes squarrose at the ape.x, rather large, 

 as much as 3 mm. long and 2 mm. wide, ovate-elliptical; above the middle dis- 

 tinctly narrowed, broadly and bluntly acuminate, at the ape.x indistinctly dentic- 

 ulate. Costa very strong, two-forked, the longer branch extending to the mid- 

 dle or a little beyond. Areolation very loose, consisting of linear-rhombic or 

 fusiform cells, the upper ones shorter, those in the middle up to 80// long, at 

 the apex frequently subacute, those at the base more loose, the alar ones few, 

 indistinct, lengthened, rectangular, hardly inflated, forming rather indistinct 

 auricles.

 Holzinger, July 29, 1898. 



"The robust appearance of this plant, its color, its very large, distant leaves, 

 spreading in all directions, give at first the impression of a distinct species; and 

 yet the comparison with numerous specimens of H. molle Dicks, shows the 

 more close affinity with this species as it is understood by Schimper, Syn. ed. II.
