NATURE NOTES. 
precipices of Snowdon, where I also came upon a single plane 
of Woodsia alpina. I have searched the Clova Mountains in 
vain for Woodsia, for Oxytropis campestris , Mulgedium alpinum, and 
Lychnis alpina, though I have collected there the rare grass, 
Alopecurus alpinus and the equally rare rush, Juncus castaneus. 
I spoke, just now, of the Polystichum Lonchitis as abundant 
amid the limestone debris (Cambrian) of West Sutherland, near 
the head of Loch Assynt. Let me add that along with it Dry as 
Octopetala grows and blooms in profusion. I have never myself 
gathered this beautiful plant, excepting here, and on the sugar- 
limestone knolls of Cronkley Scar in Upper Teesdale, where it 
grows in some abundance, but does not bloom. Associated with 
the Dry as and Holly Fern in Sutherland is the rare Epipactis 
atrorubens. Further to the north of this northern county, on 
Farout or Farrid Head, I have gathered in fair abundance the 
Primula scotica, very similar to the commoner and southern P. 
farinosa, but clearly distinguishable from it in growth and habit. 
This plant I believe to be confined in Britain to Sutherland, 
Caithness and the Orkneys. 
The reference to P. farinosa carries one across the border to 
Upper Teesdale, where it grows in profusion, and, with the 
Trollius europaiis, decks the wet pastures in springtime in lilac 
and gold. Associated with this plant, often amid the short 
grass by the side of some tiny rill or stream, may be seen in 
abundance the vivid blue of the Gentiana verna, absolutely 
restricted to this locality in England, and to be found besides 
in the British Isles only in the county of Galway in Western 
Ireland, also on the mountain limestone. The Falcon Clints, 
a range of bold basaltic rocks near the Tees Head, used to be an 
English locality for Woodsia Ilvensis and Polystichum Lonchitis; but 
these have now entirely disappeared from there, thanks to the 
selfish greed of dealers or professional collectors. But Teesdale 
still possesses several plants that are unique, or nearly so. On 
the summit of Mickle Fell Myosotis alpestris ( suavcolens ), which 
we made acquaintance with on Ben Lawers, reappears. (I say 
this not from personal knowledge.) On or under Cronkley Scar 
may be found several rare Hieracia, Tofieldia palustris, Bartsia 
alpina (close to the river on the Durham bank), a very locally 
distributed sub-Alpine plant. And lower down the stream, just 
below the High Force, Potentilla fruticosa grows, on the York- 
shire side of the stream, in considerable profusion. This plant, 
though not restricted to this locality, is very sparingly distri- 
buted, yet, oddly enough, it is also met with in counties Galway 
and Clare, in Ireland. 
One Potentilla, though not an unfrequent sub-Alpine on the 
continent of Europe, has but one British habitat. This is 
Potentilla rupestris, our one beautiful white-blossoming species. 
This must be looked for on the escarped side of that picturesque 
outbreak of trap-rock that arrests the eye of the traveller by 
the Cambrian, near Welshpool — Craig Breidden. I had the
