cologia Britannica.” One of these species is now presented to
of thfrwork
Grimmia torquata, which I had the pleasure of receiving
two years ago from my friend M. F r e u c h e n , as a MS. species
of M . H o r n s c h u c h , has never, I believe, been found
m fruit. It IS therefore only from the habit and structure
of the plant that it has been placed in the genus Grimmia.
On the rocks of our own mountains, it preserves its barren cha-
lactei, but IS so conspicuous from its large masses, and its stems
so remarkably spiral, from the twisting of the leaves, that there
IS no chance of any other moss whatever being confounded with
ri. Another peculiarity attending it is, that, though growing
in a remarkably compact manner, its stems, when gathered, separate
of their own accord, as if they had no other connection
than that of mere juxtaposition. In the Breadalbane district,
there are few mosses more plentiful; and, as may be supposed.
It has been in the herbaria of Dr H o o k e r and myself for some
years. We have never, however, succeeded in finding the least
vestige of fructification, though for several seasons we have
made a diligent search. Dr H o r n s c h u c h ’s specimens were
gathered on the Carinthian Alps.
