ON A NEW SPECIES OF HORKELIA. 341 
and other débris, loosened from the cliffs above by the rains; while 
every now and then the descent of some huge mass, at no great dis- 
tance, thundering from crag to crag, afforded a rather broad hint, not 
at all difficult to understand, that danger was not far off. 
The day thus passed on: I had only at intervals picked a few speci- 
mens of the more common plants, and had nothing else to do but ad- 
mire the “warring elements,” the “rending rocks,” and the foaming 
streams, till about five o'clock p.m., when I resolved to attempt a 
homeward march. I had just reached the foot of Glen Fiadh, when 
dark spots began to appear in the dense canopy overhead; the mist, 
which had hitherto rolled down the hills, began to roll upwards, and 
sweeping over their tops was out of sight in an instant. Ina few 
minutes the whole scene was changed: the clouds began to break away 
from the zenith, and the bright sky appeared between; the wind had 
again settled in the west, the sun burst through in full splendour, and 
the whole valleys were speedily in a blaze. It was now however too 
late to return, and I proceeded homewards, reflecting, that if the day 
was lost to botany, I had, as a native of Scotland, not only “loved her 
mountains, but enjoyed her storms.”

This was discovered and sent to me in 1844, and I have never seen 
the same very distinct species from any other source. It is distin-
