 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-

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



570. Hypiium Vauclieri Lesq. — Plants resembling certain forms of J9". 

 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, 

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

 angles more numerous and smaller than in H. cu2'>ressiforme, walls 

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

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



571. Hypnuni Reuiinldii Kindb. — Agrees with H. ourvifoUum in 

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

 Lindbergii in leaves decurreut, 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. Mao. 

 Cat. 2.38. — On earth and old logs and sometimes on rocks: British Colum- 

 bia; Canada; Newfoundland. 



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

 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: capsu 



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

573. Hypniim Patientise elatum Sch. — Extensively cespitose, tufts

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

 Syn. 758. 1876.— Miquelon Island.
