52 NEW SPECIES OF MUSCl. 



from nearly the same point arise sterile very slender shoots 

 which bear young perichsetia with their rootlets ; on different 

 sterile shoots perigonia occur. Leaves erecto-patent. Sterile 

 shoots nearly 2 inches long. 



2. B. pungens ; caule laxe casspitoso, erecto, surculis subfas- 

 tigiatis, apice incrassatis ; foliis arete imbricatis, erectis, 

 cordato-triangularibus longius atque tenuiter acuminatis 

 integerrimis, nervo percurrente ; capsula elongate pyri- 

 formi, subhorizontali. — On dry banks, on Pichincha, near 

 Quito, Prof. William Jameson, (Dr. Greville's Herba- 

 rium). 



Stems scarcely | an inch high ; shoots several from near 

 the base of the perichaetium, pale-olive, slender below, in- 

 crassated above. Leaves crowded, their setaceous points 

 only standing out from the stem, sometimes striated, their 

 margins plane. Perichaetium very short. Setae nearly 2 

 inches long, thickened above and bent nearly at right angles. 

 Capsule large compared with the stems, sometimes as long 

 as an entire shoot, the apophysis elongated and longitu- 

 dinally wrinkled. A single filiform process interposed 

 between each pair of lacinise of the inner peristome. The 

 closely imbricated, shining, yellowish-green leaves with seta- 

 ceous points, and the slender stems compared with the large 

 fruit, keep this species distinct from its congeners. 



3. B. tenuissimum ; caule laxe caespitoso, erecto, tenuissimo, 

 subramoso; ramis filiformibus, simplicibus, micantibus j 

 foliis arete imbricatis, erectis, oblongis, obtusissimis, rupti- 

 nerviis, concavis, integerrimis, margine subrecurvis, peri- 

 chaetialibus nervo excurrente longius apiculatis. — Swan 

 River, Mr. James Drummond. 



Scarcely § an inch high, pale yellowish-green, shining; 

 leaves tumid, closely adpressed to the stems. Perichaetiuni 

 axillary, ovato-lanceolate. This has the habit of Brytna 

 julaceum, Schrader. It is slenderer, and more yellow, 

 and has more obtuse leaves. The fruit is unknown, 



4. B. campy lot hecium ; caule caespitoso, erecto, ramoso, basi 

 tomentoso, apice incrassato; foliis in rosulam aggregatis,
