HAB. Moist banks and in woods, common. 



Stems creeping and branched beneath the surface of the 

 gjjund ; branches erect, three or four inches in length, 

 iSfy ; the leaves very large towards the extremities of the 

 plant. The sterile plants are procumbent. It often hap- 

 pens that many fruitstalks arise from the same point. 



22. Br. rostratum ; stems elongated ; leaves broadly ovate, re- 

 ticulated, their margins thickened, obtuse, denticulated, the 

 nerve reaching a little beyond the point; capsule ovate, 

 pendulous; lid rostrate. (TAB. XXX.)

HAB. Subalpine countries, Yorkshire. Rev. J. Dalton. 



This species approaches most nearly to Br. punctatum; 

 but the whole plant is smaller, rarely exceeding an inch in 

 height; the leaves are narrower and denticulate, of a softer 

 texture, and the nerve runs beyond the extremity of the 

 leaf, so as to form a short cuspidate point ; the lid too has 

 longer beak. Calyptra very pale coloured. Fruitstalks from 

 one to five. 



23. Er. marfrinatum; stems elongated; leav;es ovate, acute, 

 reticulated, their margins thickened, serrated, nerve reach- 

 ing a little beyond the point ; capsule ovate, pendulous; 

 shortly rostrate. (TAB. XXXI.)

HAB. Woods and shaded banks in the north of England 

 and in Ireland. 



Whole plant when growing of a very yellowish hue, 

 Stems simple, about an inch high. Leaves of a lurid green, 

 especially when dry; when seen under a microscope the 

 margin and nerve are of a deep blood colour, and the vei 

 is of a red or orange colour, which renders the moss very 

 discernible at first sight.
