12. J. sgtiarrosula, Tayl.; caule brevissimo, caespitoso, ad-

 reflexis, subdentatis. 



Hab. No. 54. On charcoal. Swan River; Mr. James Drum- 



mond. 



Tufts wide, forming low olive green cushions. Stems 

 scarcely exceeding a line in length. Leaves amplexicaul, 

 concave, their tops recurved, their sinus acute. This species 

 is far more minute and erect than Jung. Francisci, Hook., 

 and the leaves are distantly denticulate, and have a deeper 

 sinus. In the dry state it has a squarrose habit. 



13. J. asperifolia, Tayl. ; caule sparso, exili, adscendente, 

 vage ramoso ; foliis laxis, basi patentibus, apice erectis, 

 concavis, subquadratis, bifidis, segmentis acutis, margine 

 dorsoque celluloso-dentatis ; stipulis minutis, ovato-acu- 

 minatis, dentatis ; calyce terminali, oblongo, subcompresso, 

 subplicato, ore subintegro. 



Hab. On Dicranum clavatum, Schw. No. 10. Madeira; 



Dickson. 



Excessively minute, purplish-brown, ascending, scattered 

 or in very loose patches. Stems very slender; branches 

 short. Leaves bent forwards at an angle. Stipules rarely 

 bifid, ciliato-dentate. Perigonia large, ventricose, forming 

 an obtuse spike. The two lateral perichsetial leaves subtrifid, 

 ciliate, segments acuminate, the ventral oblong, sometimes 

 emarginate, seldom bifid. Calyces purplish below, the 

 colour discharged from their tops. The margins and backs 

 of the leaves are celluloso-echinate as in Lejeunia calcarea, 

 Libert. In size and habit it resembles Jung, byssacea, 

 Roth, differing essentially by the concave celluloso-dentate 

 leaves. 



14. J. glaucocephala, Tayl. ; caule caespitoso, exiguo, erecto, 

 subraraoso ; foliis laxis, ex angusta amplexante basi oblon- 

 gis, inaequaliter bifidis, segmente dorsali erecto, minori, 

 ventrali reclinato, utroque obtusiusculo, sinu obtuso.
