Synoicous ; sometimes also with gemmiform male infl. intermixed ; 

 densely csespitant and tomentose, dull green with short branches. 

 Comal leaves densely crowded, erecto-patent, ovato-lanc, carinate 

 concave, the nerve stout, far excurrent, margin more or less reflexed, 

 narrowly limbate, serrulate or entire at extreme apex, all rather rigid ; 

 cells dense, rhombic above, rectangular and red at base. Caps, rich 

 brown, pendulous, from a neck swollen at base shorter than the 

 sporangium, oval or ovato-globose, slightly contracted below the mouth, 

 shorter or longer, lid rather small, broadly conic, acutely apiculate ; 

 annulus broad ; teeth of peristome reddish-yellow at base, and according 

 to Husnot traversed on the back by many fine sinuous lines, endostome 

 adherent, the processes only partly free, cilia rudimentary. 



Hab. — On walls, rocks and waste ground ; not uncommon. Fr. 5, 



Very variable in size and form of capsule and differing ixom. B . inclinatum 

 by the broader leaves and more ventricose capsule with adherent endostome, 

 and from B. ccgspiticium by the small mouth of capsule, the infl. and endostome. 



6. BRYUM PURPURASCENS {R. Br.) By. Sch. 



Synoicous; plants slender dull green, purplish at apex. Leaves 

 ovato-lanc, mucronate with the excurrent nerve, narrowly limbate, 

 slightly recurved at margin. Caps, pendulous, oblongo-pyriform, lid 

 hemispherical, cilia imperfect. (T. LXXII, A.)
