NOTES ON THE FLORA OF PERTHSHIRE 165 



and Saxifraga cernua were not less plentiful than they were 

 twenty years ago ; but S. rivularis is so scarce that a single 

 collector might easily eradicate it. The rich rocks of Creag- 

 an-Lochain had one day allotted to them, when Hieracium 

 insulare, vwc.petrockatis, was in especially fine flower. Another 

 day was devoted to the Perthshire side of Beinn Laoigh. 

 Mr. H. N. Dixon has already elsewhere given an account of 

 the mosses he found on his expedition to Beinn Heisgarnich, 

 which was first alluded to as a botanical hunting-ground in 

 Lightfoot's "Flora Scotica " of 1774, where it is called Ben 

 Teskerney. It took some considerable time, for a Southron 

 unversed in Gaelic, to identify this with the mountain on the 

 Ordnance Maps spelt Beinn Heisgarnich. This hill is 

 situated about ten miles from Tyndrum, on the south-eastern 

 side of Loch Lyon ; and the walk to it from Tyndrum, which 

 we shortened by taking a machine for three miles, is at the 

 best a long and wearisome approach by the Allt Chonoglais, 

 although Beinn Doireann rears its finely shaped mass boldly 

 up to the north, and the south-eastern side is blocked by 

 the bold cliffs of Beinn a Chaisteil. Afterwards there is 

 little to interest one as one passes by the south of Beinn 

 Vennoch to Loch Lyon, at the head of which there is con- 

 siderable marshy ground worthy of systematic investiga- 

 tion. We made the ascent of the western shoulder of Ben 

 Heasgarnich, on which, and in the corrie, there is a large 

 deposit of peat ; and eventually, after a rough climb, were 

 rewarded by a sight of the magnificent cirque with a grand 

 rocky coronet, which would require many visits to work with 

 any degree of finality. The summit, 3530 feet high, is not 

 particularly interesting, and the descent to Allt Foinn-a- 

 Glinne is down a grassy slope of a very considerable degree 

 of steepness. Although there is no loch in the corrie, a 

 multitude of small watercourses offer some very interesting 

 botanising. Another day was spent on Glas Thulachan, 

 which we visited from the Spital of Glenshee, and this also 

 necessitates a rather wearisome walk by the Allt Ghlinn 

 Thoilneicht to its junction with the stream issuing from Glas 

 Thulachan itself. The corrie is rather extensive, but the 

 rocks are not very bold at any rate they did not seem so 

 to ourselves, just fresh from the precipices of Lochnagar.
