Hab. On the ground in wet springy places and margins of swamps in 

 the Southern States; not uncommon. 



Allied to B. rigida, a European species, which has less linear leaves 

 with only the lower surface papillose, reflexed margins, a thicker shorter 

 pedicel, and an oblong-globose capsule with a thicker outer membrane. 



B. WiLSONi, Muell., is reported in Rau & Hervey's catalogue as found 

 in New Jersey by Austin. We have seen no other mention and no speci- 

 mens of it. It is a small plant, with soft subsecund leaves; capsules ag- 

 gregated in the same perichsetium, very soft, on arcuate pedicels, globose- 

 pyriform, without peristome. 



76. CONOSTOMUM, Swartz. (PI. 3.) 

 Plants erect, in small compact tufts, fastigiately branching, 

 tomentose-radiculose. Stem-leaves equal, the comal longer, 

 densely crowded, imbricate in five ranks, the stem aj^pearing 

 pentagonal ; areolation of the leaves the same as in J^artramia. 

 Flowers dioecious, the male discoid. Calyptra cucullate, per- 

 sistent. Capsule long-pedicellate, cernuous, inflated, obovate 

 from a short collum ; lid small, straight-beaked. Peristome 

 simple, of 16 solid linear-lanceolate teeth, joined into a cone 

 and agglutinate at the apex. 



1. C. boreale, Swartz. Tufts glaucous-green above : lower 

 leaves lanceolate, costate to below the apex, the upper narrowly 

 lanceolate, longer cuspidate by the excnrrent costa, all carinate, 

 serrate above, opaque and brittle ; pericha^tial leaves numerous, 

 larger, thinner, Avith a slender costa ; outer perigonial leaves 

 lanceolate from a broadly concave base, the inner gradually 

 shorter : capsule sulcate when dry, cernuous ; teeth latticed,
