(193.) B. carnifolia, C. M. & Kindb. (n. sp.) 



Stem very short, 2-3 mm. high. Leaves lingulate, not margined, 

 blunt ; margins recurved below and above the middle at one side ; cells 

 finally sub-pellucid, the upper sub-quadrate, also the median, the lower 

 basal near the costa large, rectangular and hyaline, the marginal 

 shorter and narrower, costa red, thick, and sub-percurrent or rarely 

 short excurrent. Inner perichetial leaves smaller and shorter 

 Capsule longer than the straight lid ; pedicel about 1.5 cm. long. 

 Probably dioecious. 



(194.) B. subcarnifolia, C. M. & Kindb. (n. sp.) 



Smaller than B. carnifolia, differing principally in the leaves being 

 short, suboblong, short-apiculate, the upper pellucid at the flat margins, 

 the costa green. Probably monoecious. 



Differs from B. amplexa in the capsule being longer than the 

 oblique lid.

(195.) B. platyneura, C. M. & Kindb. (n. sp.) 



Dioecious. Tufts compact subpulvinate, light brown. Stem scarcely 

 1 cm. high. Leaves suberect, when dry imbricate and contorted r 

 short, ovate or ovate-oblong, subacute, papillose ; margins strongly 

 revolute ; basal cells short-rectangular, the other subquadrate ; costa 

 thick, short excurrent or per current. Barren. 



Nearly allied to the European B. revoluta, Schrad., but clearly dis-
