BOTANICAL NOTES OF A TOUR IN CAITHNESS AND SUTHERLAND. 337 



the road to Badcall, about half-way between it and Scouric, is Locban 

 Dubh, in which Potanioi/eton nit ens was growing; and a low hundred 

 yards further a piece of marshy ground, in whicli Carer, liinosa and 

 Vtricularia interi)icdia were abundant, tiie latter without a trace of 

 flower. On rocks south-west of Scourie Asplenluiii iinirinum wag 

 growing scantily, Litiusticuin scotictim and Sediwi Hhoiliuhi plentifully, 

 and on crags at Badcall was Hieracium pallidum. 



The long drive to Lairg yielded nothing of special interest. 

 Birch-trees clothe the lower parts of the hills. Populns Ireinnla and 

 Horn spinosissima cling to the rocks. A few hollies and an occasional 

 stunted oak give variety to the higher foliage. 



To those who could give longer time than our hurried tour 

 allowed us, and could include some of the higher mountains, as 

 Morven, Ben Hope, Foiniven, and Ben Arkle in their search, the 

 two counties would doubtless yield many other plants of interest ; 

 but our notes are enough to show that there are few districts in 

 Great Britain where a walk of ten days would bring within reach 

 of the botanist so rich and varied a flora.
