NEW BRITISH MOSSES. 175 
ton, near Manchester, growing with Br. pallens ;”* Dr. J. B. 
Wood and Mr. Buxton. “In one of the highest branches. 
of the Wythburn Beck, near the junction of Cumberland 
and Westmoreland ;" Mr. Borrer. 
This is most nearly allied to Br. pallens, Swartz, (Br. tur- 
binatum, Musc. Brit.), but may be distinguished by the fol- 
lowing characters. 
Leaves much larger, more erect, proportionally narrower 
and tapering more towards the point, very distinctly margi- 
nated, the upper of a bluish-green hue, those towards the 
base gradually assuming a tinge of red, especially on the 
nerve; but the redness of the foliage in Br. pallens is quite 
characteristic of the species. Inflorescence monoicous, (dioi- 
. cous in Br. pallens) ; male flowers much smaller and contain- 
. ing fewer antheridia, the outer perigonial leaves not recurved. 
Capsules usually larger, irregular, the sporangium propor- 
. tionally not so wide, and the collum quite equalling it in 
. length; the mouth in Br. pallens is oblique, but less so than 
. in Br. uliginosum, which resembles in this respect Br. Zierii 
and demissum. Operculum distinctly apiculate. Teeth of 
Outer peristome acuminate. Inner peristome destitute of 
cilia or with merely rudimentary ones; that of Br. pallens 
normally ciliate, yet not uniformly so. 
The capsules of Br. uliginosum vary in direction from hori- 
. Zontal to pendulous; in Mr. Ibbotson’s specimens they are 
quite pendulous, regular, and the mouth is scarcely oblique. 
. When just mature they are usually of a milk-white hue ; but 
in my Castle-Howard specimens, which grew exposed to the - 
dripping of water, they are deep brown on the upper, and 
greenish on the under surface. 
* The Bryum turbinatum of Hobson's British Mosses is a mixture of Br. 
uliginosum and pallens from this locality. 
T Instances have been found by Mr. Wilson among Dr. Wood's Pilking- 
T Specimens of Br. pallens, of capsules whose inner peristome is furnished _ 
with merely rudimentary cilia, and I have myself gathered a var. on Stock- 
ton Forest, in which they are entirely wanting. | or ue
