(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, shortapiculate, 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. 



On earth at the base of trees, Pelee Island, Lake Brie, 13th June, 

 1882. {Macoun.) 



(e.) SENOPHYLLUM, C. Muell. 



(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, 

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

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

 thick, short excm'rent or per current. Barren. 



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

 tinct in the always shorter, and less obtuse leaves.
