DISCOVERED at the falls of Moness by Aberfeldy, in the
Highlands of Scotland, in 1808, by Mr. W . Borrer and Mr.
W . J. Hooker, but without fructification. That deficiency
we have supplied from East Indian specimens, exactly agreeing
with the British ones, which we have the authority of our
intelligent friend last named to say, are what is called by mistake
B.fontana in his paper on Nepal Mosses, Tr. of L. Soc.
v . 9 . 3 1 7 .
This species has extremely the aspect of B.fontana, (Bryum
fontanum,) t. 3 9 0 , but when examined with a common magnifying
gla.ss, the leaves are found much more closely imbricated,
ranged in 4 or 5 spiral rows, lanceolate, with longer
more taper terminations^ and when more highly magnified
they prove to be finely serrated, which Mr. J. D. Sowerby has
first detected, for Hedwig represents them entire. Several
young, short, leafy, angular branches are clustered round the
base of each fruitstalk, which rises much above them, being
near 2 inches long, red, rather stronger than in the fontana.
The capsule is somewhat smaller and more globular, but
scarcely any difference is observable in the lid.
