3GG NOTES ON THE FLORA OF BEN LAIOGH, ETC. 



The second day I drove about ten miles along the Dalmally 

 Eoad and forded the River Lochy, worked the moorland on the 

 Argyll side, and then the calcareous cliffs up the Eas Daimh 

 stream to the Perth boundary ; finding them so rich as to induce 

 one to return by them at a slightly different level into the great 

 Argyll corrie, whose cliffs, up to its head, were worked, and then its 

 southern cliffs. This gave one of the best day's botanising of the 

 season, and the day was clear and pleasant. A third and less 

 agreeable day was occupied in working the Tyndrum moorland, the 

 rocks, ravine and waterfall of Ben Chuirn, and the Perthshire 

 cliffs of Ben Laiogh parallel with the Coninish burn up to the 

 watershed. A fourth day was spent at Dalmab'y and the upper end 

 of Loch Awe, and of course has nothing to do with Pen Laiogh. 

 I have to thank Mr. Dakin, of the Geological Survey, and Mr. 

 Franklin T. Richards, for kind assistance. 



Below is a detailed list of interesting plants noticed. Many 

 critical specimens are still under investigation. Mr. Arth. Bennett, 

 Prof. Babington, Prof. Haussknecht, Dr. Buchanan White, and 

 Mr. F. J. Hanbury have rendered help in plant discrimination. 

 Supposed additions to Top. Bot., ed. ii., are marked.* Those species 

 without personal authority iu that work are marked f . Without 

 giving precise localities, I may say that I gathered in Argyllshire 

 Cijstopteris mmtana Bernh., which occurred in great profusion and 

 luxuriance.

drains )><>tr<ea Lamk. This is entered in Top. Bot. for Mid 

 Perth on the authority of Lightfoot's Flora. In the Perthshire 

 corrie and on the cliffs in both counties occurred a form of this 

 species very distinct in appearance from the Cairngorm plant. It is 

 well marked by its very much larger size, by its much larger, I 3 

 deeply-cut leaves which are of a thinner texture and different colour. 

 The flowers are larger and with more spreading petals. It appears to 

 be worthy of varietal distinction and may be designated var. grandi- 

 folia. The leaves vary much as to leaf cutting, but are never so 

 deeply cut as in the Cairngorm plants. They vary also from 



nearly glabrous to hairy.

 the Laiogh Glen.
