320 BRVACE^:. 



when dry an obtuse rounded tuft ; all very concave, widely 

 elliptical or sub-orbicular, obtuse or shortly and obtusely 

 apiculate, not bordered, margin entire or faintly sinuose at apex, 

 plane or very narrowly recurved below ; nerve strong below, 

 vanishing below or more rarely just reaching apex ; cells shortly 

 and widely rectangular-hexagonal, hardly altered at margin; 

 comal leaves of the fertile stem narrower, ovate-oblong, 

 acuminate. Seta i-iyi inches long, firm; capsule exactly 

 pendulous, oval-pyriform with a short, sometimes almost 

 obsolete neck, the mouth rather narrow ; lid conical, mamillate ; 

 peristome teeth yellow, darker at base ; cilia rudimentary. 

 Autoicous ; male flower gemmiform, just below the fertile flower. 



Hab. Sandy shores and damp places, rare. Fr. summer and autumn. 



This species and B. Marratii are very distinct in the extremely concave, obtuse 

 leaves, of very different outline from the typical Bryum leaf. The capsule of B. 

 Marratii, sub-globose pyriform and acuminate with the pointed lid, and the 

 narrower, oblong, more obtuse leaves easily separate that species from the present ; 

 B. Wariteum differs in the longer, cuspidate, serrate points of the leaves, and in the 

 distinct structure of the peristome teeth. The fruit ripens over a long period of the 

 year. 



5. Bryum Marratii Wils. (Tab. XLIII. D.). 



Resembles B. calophyllum, but differs in the narrower, 

 oval-oblong leaves, which are more obtuse, entire, very concave, 

 somewhat cucullate at apex, the nerve rather narrower, vanishing 

 below apex. Seta shorter, more slender, capsule small, globose- 

 pyriform with a very short, tapering neck, apiculate with the 

 rostellate, acuminate lid, sub-pendulous, small-mouthed, dark 

 reddish brown ; annulus broad, persistent ; peristome teeth 

 narrow, deep orange-red; cilia rudimentary. Autoicous; male 

 flower gemmiform. 



Hab. Sandy sea-shores. Rare. Fr. late summer and autumn. 



Readily known from B. calophyllum by the characters italicised, and also pointed 

 out under that species. The deep red colour of peristome is also characteristic, and 

 the capsule is of a very different form from that of any of the allied species. 



6. Bryum purpurascens B. & S. (Pohlia purpurascens R. Br.) 



(Tab. XLIII. E.). 



In tufts, brown or purplish red above. Leaves resembling 

 those of B. inclinatum but rather wider, more shortly acuminate , 

 margin less recurved, bordered with several rows of narrow, 

 yellow cells, slightly denticulate at apex, nerve yellowish,
