Native. Ericetal, Pascual. Apparently very rare in the 

 Peninsula, for which I find only one locality on record ; 

 namely, in Devon. At the opposite extremity of Britain, 

 or the province of the North Isles, two or three localities 

 are known in one of the groups ; namely, in Orkney. In 

 1848, Mr. C. C. Babington wrote me to this effect : " I never 

 saw specimens of Gnaphalium norvegicum, as I now find, 

 before receiving some good ones from ' a lofty craig at the 

 head of Canlochen Glen, above Glen Isla, Forfarshire,' — 

 Mr. James Backhouse." The habitat thus indicated would 

 carry the species up to 800 or 900 yards, and into the mid- 

 arctic zone, in the East Highland province ; unless the G. 

 norvegicum should be geographically treated apart fi-om 

 G. sylvaticum. A specimen is preserved in my herbarium, 

 collected in Glen Isla, in 1834, by Mr. Brand, which I 

 presume to be the G. norvegicum ; but which appears so 

 linked to the G. sylvaticum or rectum of English botanists, 

 by intermediate forms, as to render discrimination very 

 difficult and unsatisfactory. A doubt is attached to the 

 existence of Gnaphalium sylvaticum or rectum in the Isle 

 of Wight ; Dr. Bromfield having been unable to find it in 

 the locality where Mr. Joseph Woods reported it as being 

 frequent.
