the Flora of Glen Lyon. 483 



environments was discovered. A little tarn filling a hollow, 

 and supplied with water from a large snow wreath about 

 60 feet above, had its margin bordered with a dense growth 

 of Caliha palustris, whose flowers formed a rich yellow 

 carpet. Such a striking local climatic effect, seen in the 

 height of summer after broiling days of heat, impresses 

 on one the importance of noting local conditions as bearing 

 on tlie flora and fauna of any district. 



What proved to be the best " find " of our party was 

 made by Mr Brebner while botanising along the face of 

 the corrie. In 1810 Don reported that he had found 

 Carex ustulata, Wahl, on the Breadalbane mountains, but 

 as it had never since been confirmed, it was classed by 

 Hooker, in his appendix to the Student's Flora, as " ono 

 of Don's reputed discoveries"; but three specimens, gathered 

 by Mr Brebner and forwarded to Dr Buchanan White, have 

 been identified by him, and confirmed by Mr A. Bennett 

 of Croydon, as Don's plant. The smaller and more slender 

 liabit, nodding head, and different hue, all separate it in 

 appearance from C. atrata, with which it might be at 

 first confounded. And here we may be allowed to do 

 honour to the memory of that most indefatigable of all 

 our early Scotch alpine botanists, whose "finds," once 

 regarded as doubtful or mistaken, are being all verified, 

 year by year, as a more perfect knowledge of our hill flora 

 is obtained.* 



We reached our headquarters about 7 p.m., thoroughly 

 satisfied with our day's botanising, and convinced that this 

 hill, which has received so little attention from botanists, 

 is worthy of all praise. 



On Friday, an accident happening to one of our number, 

 we were prevented setting out for the hills till twelveo'clock, 

 when it was resolved to circle Ben Vannoch, 3100 feet 

 high. Nothing of importance was gathered. On the 

 succeeding morning an early start was made for Tyndrum 

 station, which was reached after a tough walk under a 

 burning sun. 



* Note. — Qth October 1886. — Mr Brebner, along with two accomplished 

 botanists, revisited the spot during the past summer, and were gratified to find 

 that Carex ustulata was pretty plentiful. Specimens of it are now deposited 

 in the Herbarium at the Royal Botanic Garden.
