Native. Ericetal. Not enumerated by Mr. E. Forbes 

 among the plants of the Isle of Man ; but the omission of 

 various willows from many local lists may frequently be 

 attributed to uncertainties regarding their nomenclature. 

 Possibly S. fusca, in some of its various forms, may be 

 found in the midarctic zone, since it really does attain the 

 lower level of some truly alpine plants in peculiar situa- 

 tions ; as, for example, that of the Sibbaldia procumbens 

 in the pass from Glen Shee towards Castletown in 

 Braemar.

Native. Rupestral. Said to grow on the Clova Moun- 

 tains, and on the banks of the Nith, above twenty miles 

 from Dumfries. The name occurs in Lowe's or Barry's 

 Orkney list ; but it is impossible to say what species was 

 there intended. The shrub is unknown to me, and I can 

 only give a rough and imperfect approximation to its 

 distribution, grounded on these very few records of its 

 localities.
