142 BRITISH FERNS. 
me that near that town he found it growing on hedge- 
banks, exactly as Trichomanes does in this country: the 
specimens were correctly named, and I have received — 
similar information from Professor Duval-Jouve, of 
Grasse. As the climate is peculiarly mild and the alti- 
tude of Grasse but little above the sea-level, this habitat 
seems at first rather abnormal ; but this, as well as other 
facts connected with its singular habitats, may perhaps 
lead to the conclusion that the geographical distribution 
of this pretty little fern is governed by some geological 
law rather than one of climate or altitude. In England 
T have found it growing in considerable abundance on 
an old garden wall at Mickleham, in Surrey ; a fruit 
tree is trained on the wall, and the green fronds of 
the fern are intermixed with the leaves of the tree. 
_ The garden in question is occupied by a trainer of 
-race-horses well known to the dwellers in this pretty 
village: it occurs in a similar locality at Danny, near 
_ Brighton; and also formerly in Mr. Owen’s garden 
at Maidstone, in Kent. In Worcestershire, it occurs 
in a very starved and diminutive ‘state on Ham 
Bridge, near Sapey Brook, in the valley of the Teme:
