FLORA OF FORFARSHIRE. 
440) are referred by Babington, 386, and Newman, 58, to 
Lastrcea dilatata, Presl., and are, with many intermediate 
forms, plentiful throughout the county, especially in woods 
and in rocky places on the mountains. The var. recurvum , 
Bree., has been found in the woods of Baldovan, Kinnordy, 
&c., but is not common.

The former of these is frequent among the mountains, as 
Ben Red, Bassies, Craig Maid, Canlochen, &c., with fronds 
from two to eight inches high ; the latter is abundant in 
shady dens, as those of Airlie, Glammis, Bonnington, Fuller- 
ton, Foulis, Pitairlie, &c., from three inches to upwards of a 
foot high. Both love moisture and shade, and thrive best in 
the crevices of wet rocks, yet I have found the fragilis asso- 
ciated with Asplenium Trichomanes among loose stones on 
the summits of the Sidlaw Hills. The extreme forms of 
these beautiful and- delicate ferns appear distinct enough to 
the eye, but fronds with pinnae and pinnules of all interme- 
diate shapes occur, so that one feels it often difficult which 
name to apply.

“ On rocks,” Mr G. Don. I am not aware in what part 
of the county these rocks are situated, or whether any other 
botanist has found them. Arthur’s Seat, near Edinburgh, 
and Stenton Rock, near Dunkeld, are perhaps the only Scot- 
tish stations known at present.
