BARNES NORTH AMERICAN MOSSES. 361 



stems creeping, densely pinnate ramulose; branches robust, thick and 

 tumid: leaves close, falcate, with elongate-ovate or oblong base and short 

 acumen, faintly or not striate, more or less denticulate all around, not re- 

 flexed on borders, larger than in H. imponens; cells very narrow, alar 

 larger and pellucid, other basal cells yellow; paraphyllia few, subulate; 

 perigonial leaves very broad-ovate, abruptly narrowed to a straight subu- 

 late point: capsule obovate, asymmetric or sub-cylindric and arcuate, 

 thick and not striate; teeth yellow; segments orange, cilia short and 

 not appendiculate. Mac. Cat. 236. Newfoundland; Alaska; on stones: 

 Nova Scotia and Quebec; on rotten logs: Rocky Mountains and Ontario. 



569. Hypnum cupressiforme Pyreniacum Ren. Closely related to 

 the variety filiforme, from which it is distinguished by the short acumin- 

 ate leaves, quite strongly dentate. Fl. Miq. 55. Miquelon Island. 



570. Hypnnm Yaucheri Lesq. Plants resembling certain forms of H* 

 cupressiforme : stems erect-fastigiate: tufts compact, dark green or 

 yellowish: leaves crowded and imbricate, more or less falciform-secund, 

 sometimes erect so as to give branches a sub-julaceous appearance, oval or 

 oval-lanceolate, entire or sinuolate, plane on borders; costa very short r 

 simple or bifurcated, one branch longer than the other; cells of basal 

 angles more numerous and smaller than in H. cupressiforme, walls 

 thickened, middle cells broader and shorter, 6-8 times as long as broad: 

 fruit unknown. Husnot, Muse. Gall. 406. Montana. 



571. Hypnum Renanldii Kindb. Agrees with H. curvifolium in 

 stem more or less pinnate, inner basal leaf cells finally yellow: with H. 

 Lindbergii in leaves decurrent, alar cells very much dilated, capsule 

 not plicate when dry: differs from both in entire leaves. H. pratense 

 differs in leaves not striate nor decurrent, and alar cells not evolute. Mac. 

 Cat. 238. On earth and old logs and sometimes on rocks: British Colum- 

 bia: Canada; Newfoundland. 



572. Hypnum Patientiae Lindb. Closely related to H. pratense: 

 differs from it by stems and branches not complanate, curved at summit: 

 all leaves falciform-secund, broad oval-lanceolate, with a larger, entire 

 acumen; costa none or double and very short; cells of basal angles large, 

 forming hyaline auricles; middle ones linear, attenuate: c 



dric, arcuate, rarely fruiting. Husnot, Muse. Gall. 406. On rocks: New 

 Brunswick; Greenland; Miquelon Island; Newfoundland; Pennsylvania; 

 Indiana; Wisconsin; Montana. 



573. Hypnnm Patientiae elatum Sch. Extensively cespitose, tufts 

 yellowish or faintly rufescent: stems 2-3 inches long, erect, sub-fastigiately 

 branched: leaves falcate and sub-hamate, narrower, long acuminate. Sch. 

 Syn. 758. 1876. Miquelon Island. 



574. Hypnum Patientiee demissum Sch. Tufts deplanate, pale or
