SALIX— PINUS. ots 
Salix repens L. British type. Native. Area general. 
Range 0-550. Common in heathery ground, ascending to 
Cronkley Scars. Salix rosmarinifolia has been reported from 
Semer Water and Saltergate, probably in error for this species. 
Salix herbacea is mentioned as a North Yorkshire plant by 
R. Teesdale, but is not known to me as stich. 
Myrica Gale L. British type. Native. Area6.43. Range 
0-200. Plentiful in Askham Bogs and in the Vale of Pickering 
in swampy fir woods one mile south-west of Ayton. It occurs 
also in several of the dales of the eastern arenaceous hills, in 
Eskdale south of Castleton, and is plentiful in Goathland dale, 
Newtondale (Fen Bog), and Harwood dale. In the Scotch 
Highlands it ascends to an elevation of 560 yards, but it is not 
known to me as a plant of our western hills, and in the east its 
known stations are all clearly within the lower zone.

Pinus sylvestris L. Scottish type. Denizen. Area 
general. Range 0-450. This is a tree of the post-glacial peat 
Swamps, and at the present day is frequent both in the low 
country and amongst the hills. Entire woods of it are not un- 
frequent, as between Gilling and Helmsley, and a clump or row 
of trees may often be seen upon the north and east of houses in 
exposed situations. Whether any of the trees now in existence 
are the descendants of the aboriginal possessors of the soil may 
be doubted, and it is quite impossible to decide confidently. 
Larix europea is still more frequent than the Pinus, and forms 
extensive plantations in the dales and in exposed sterile tracts 
both in the low country and amongst the hills where no other 
tree succeeds. Abies excelsa is frequent in plantations both in 
the low country and amongst the hills, and will prosper in 
damper situations than suit the two preceding, but is not so 
hardy ; and Adves pectinata, though not nearly upon a par as 
regards frequency with the other three, is occasionally to be 
seen. ‘There is a considerable quantity of it in Deepdale woods. 
Taken together, these planted Conifere are doubtless as plenti-
