NEW SPECIES OF MUSCI. 51 



elongated cone. Peristome of filiform twisted teeth. In the 

 dry state the twisted leaves give to the shoots the habit of 

 Racopilum tomentosum, Swartz. 



7. B. crassinervia ; caule aggregate, simplici, humili ; foliis 

 in rosulam congestis, obovatis, obtusiusculis, apiculatis, 

 margine recurvis, nervo incrassato, siccitate eontortis 

 atque incurvis ; capsula erecta, aequali, elongate ovata ; 

 operculo-conico rostellato. — Swan River, Mr. James 

 Drummond. 



Stems minute. Leaves pale green, the nerve thickened 

 above. Setae slender, pale red. Peristome short, twisted. 

 From Barbula rigida, Hedw., the present species is at once 

 distinguished by the nerve incrassated above, and by the 

 reflexed margins of the leaves. 



8. B. rufiseta ; caule caespitoso, brevi, subsimplici, erecto ; 

 foliis linearibus acuminatis integerrimis, margine reflexis, 

 siccitate intortis ; capsula cylindraceo-ovata, erecta ; oper- 

 culo subulate — Swan River, Mr. James Drummond. 

 Stems 1 or 2 lines long, crowded. Leaves linear, acute, 



pale olive-green, when moistened opening in a stellate 

 manner, twisted and variously incurved when dry. Capsule 

 narrow; peristome of sixteen filiform, bipartite, twisted teeth. 

 Setae about | inch long, red, flexuose. The very narrow 

 iinear leaves, twisted when dry, separate this species from its 

 described congeners. 



Bryum, Linn. 



"' tobolifervmi caule fertili (seu pericheetio) brevissimo, 

 foliis congestis; sterili elongato filiformi erecto, foliis 

 distantibus, omnibus lanceolatis, margine planis, subser- 

 rulatis ; capsula elongate pyriformi nutante, operculo 

 eornco ; ciliis solitariis inter peristoma interni lacinia inter- 

 jectis. — n. 328. On Pichincha, near Quito, Prof. Wil- 

 tiam Jameson, It 42. 



Dioecious. Tufts loose, brownish-green. From the base 

 the fertile shoot (or perichsetium) rootlets are sent down ;
