CRYPTOGAMIA MUSCI. 37 



16. BRYUM. 



Margins of the leaf entire, or only obscurely serrate at the point. 



1. B. carneurriy stems short, simple, or branched with innova- 

 tions; leaves rather distant, ovate-lanceolate, reticulated, ob- 

 scurely serrulate at the point ; fruitstalks inch ; capsule turbi- 

 nate, pendulous. 



Hal. Ditch banks, not common. Spring. 



2. B. argenteum, stems short, branched at the base; leaves 

 closely imbricate, broadly ovate, acuminated, concave, nerve dis- 

 appearing below the point ; fruitstalks less than an inch ; capsule 

 oblong, pendulous. 



Hab. On walls, thatched roofs, and gravel walks, very 

 common, and conspicuous from its remarkable silvery 

 appearance. Spring. 



3. B. caspititium, stems short, branched ; leaves ovate, acumi- 

 nate, the nerve excurrent ; fruitstalks 1 inch ; capsule obovate, 

 pendulous. 



Hab. On walls in cushion-like tufts, common. Spring. 



The small variety which SMITH describes as B. bicolor, Fl. 

 Brit. 1355, occurs occasionally in moist clay spots on our 

 sea-banks, where it is conspicuous in spring by its large 

 dark red capsules. 



4. B. capillare, stems branched ; leaves obovate, twisted when 

 dry, the nerve produced into a hair-like point ; fruitstalks up- 

 wards of 1 inch ; capsule oblong, pendulous. 



Hab. On trunks of old trees in woods, in large dense even 

 patches ; also on turfy banks in moors. 



5. B. turbinatum, stems short, branched with innovations; 

 leaves ovate-acuminate, the nerve excurrent; fruitstalks 1| inch; 

 capsule elongate, pyriform, pendulous. 



Hab. In sandy moist places on moors. Spring. A va- 

 riety of this species, I presume, with the leaves of a 

 rose-red colour, is of frequent occurrence on stones and 

 rocks by the sides of rivulets, but it does not bear cap- 

 sules. Distinguished from B. ccespititium more by its
