Synoicous or heteroicous, in loose tufts, dull green below, purplish 

 at apex. Stems slender with innovations from below the perichsetium 

 which are sometimes flagelliform, with a few small leaves. Lower 

 leaves ovate, acute, upper oblongo-Ianc, patent, twisted when dry, 

 mucronate with the excurrent yellow nerve, concave, narrowly limbate, 

 margin slightly recurved, entire or with i — 2 irregular teeth at apex ; 

 cells at base rectangular, above rhombo-hexagonal. Perich. bracts 

 lane, more acuminate ; seta red, bent suddenly at top. Caps, pendu- 

 lous, oblong-pyriform with the neck shorter than sporangium, regular, 

 pale fuscous, rufescent at neck ; annulus large, lid small hemispherical, 

 mammillar, of the same colour as caps., peristome yellow, processes of 

 endostome free, lane. — subulate, cleft, cilia imperfect. 



Hab. — Crevices of limestone rocks, very rare. Fr. 7. Near Litton, Yorks. 

 {Whitehead 1879) ! 



The single plant sent by Mr. Whitehead quite agrees with Norwegian 

 specimens of this scarce moss, except that it is more stunted and 

 consequently the stem, leaves and capsule are shorter. Another closely 

 allied species (Br. arcticum R. Br.) is more frequent in Scandinavia than the 

 present one and is not unlikely to occur here ; it has more acuminate leaves, 

 with longer points, and a ferruginous border.
