 it above Pitmain, in the Highlands, about 750 feet ; Dr.

 Petermann saw it in flower, in a garden, at Carour, West 

 Inverness, which he calculated to be 1740 feet.

 and Mr. Petermann says even up to 1 740 feet at Carour. 

 Though not enumerated by Balfour and Babington, in 

 their list of Hebridean plants, I have ventured to include 

 that group of isles in the comital census, and so take it at 

 the full number, instead of 81.
