about Aberarder, where I was much interested in observing that 
at Glen Marson it grew plentifully, when protected by the shel- 
tering canopy of the fine old junipers (which are abundant there), 
and nowhere else than beneath their shade : it was on the 13th 
September, 1842, and all the Dryopteris was of an autumnal 
browm hue. On the 17th of the month, in a more open locality, 
about the waterfall of the Nairn, the plant was in the highest 
perfection, displaying its lovely and tender green fronds.” Mr. 
Watson found it on Ben Aulder and at Dalwhinnie.
