Head, and in a rivulet north side of the Western Mountains, at an 

 altitude of about 2000 feet, Mr. Archer. 



Notwithstanding the observations of M. C. Miiller, there appears to 

 be no real difference between these and European specimens.

 Hab. Tasmania, east side of Ovens Creek, Mr. Archer. 



B. FRAGiLis {Mitten). Dioica? dense caespitosa, caule erecto sub- 



simplici, foliis densis fragillimis erecto-patentibus e basi appressa laxe 



vaginante oblonga superne paululum dilatata ibique tenuiter hyalino 



marginata laxe areolata subito subulato longe lanceolatis cellulis ob- 



scuris densis nervo percurrente margine dorsoque serrulatis, perichae- 



tialibus lanceolatis inconspicuis, theca in pedunculo breviusculo rubro 



globosa plicata erecta, operculo brevi conico, peristoraio externo nor- 



mali interno processibus brevissimis rudimentariis. 



Hah. On rocks, rivulet behind Cumming's Head, Western Mountains, 



Tasmania, Mr. Archer ; New Zealand, Mr, Kerr. 



More densely and compactly caespitose than B. papillata. Hook. fil. 



et Wils. The subulate portion of the leaf wider, less papillose, and not 



so obscure. The inflorescence appears to be dioicous. The leaves are 



so densely congested that the vaginant base is not erect, but only ap- 



pressed to those above it, and the slightest touch suffices to detach 



them from the stem.

 P. pusilla. (Conostomum, Hook. fil. et Wils. in Fl. Nov. Zeland.)

Bartramia {Philonotis) curvirostra, Mitten, collected in Victoria, Au- 

 stralia by Dr. F. Miiller j belongs to the same section as the two fore- 

 going species, but is much smaller.
