Native. Sylvestral. If it be a correct suggestion (N. 

 B. G.) that " C. strigosa," so marked in the Ross Cata- 

 logue, really intended C. sylvatica, the North Highland 

 province may be added to the area. But until it shall be 

 fau-ly ascertained to occur in the North or West High- 

 lands, its distribution will approximate it towards the 

 English type. I do not know of its occurrence farther 

 northward than Lanarkshire, on the western side of 

 Scotland ; but the county of Dumbarton might perhaps 

 be assumed, on account of the species being given as 

 " frequent " in Flora Glottiana. In England, it may have 

 a comital generality, or nearly so. Rare on the moun- 

 tains of the Highlands, but I possess a specimen gathered 

 on the Clova mountains in 1832, at " 2000—2500 feet," 

 according to my note at the time. Supposing no mistake 

 to have occurred about the station of that specimen, it 

 helps to sanction an indication of the British t^^e, by 

 extending the zonal and climatal range of the species.
