REPORT ON THE EXCURSION OF EAST OF SCOTLAND UNION OF 

 NATURALISTS' SOCIETIES TO KILLIN IN T887. 



By R. H. Meldrum. 



This excursion occupied three days (Thursday, Friday, and Saturday, 

 14th, 15th, and 16th July). On Thursday the party proceeded from 

 Perth by rail to KHlin Pier ; and thence ascended Cam Creag, a 

 spur of Meall-nan-Tarmachan. Here Kohresia caricina was found, 

 along with many other interesting alpine plants, including the rare 

 Gentiana nivalis, Sesleria ccerufea, Carex atrata, Salix reticulata, Draba 

 incana, Tofieldia palustris, &c. From Cam Creag the party proceeded 

 towards Craig-na-Caillich, gathering on the way Juncus bigUanis, 

 Carex capillaris, Saussurea alpina, Saxifraga nivalis, Poteiitilla macu-

 na-Caillich the way was taken to Meall-dun-croisg. Here, in a 

 marshy spot, Carex limosa, Carex pulla, and Carex pauciflora were 

 gathered ; and on the rocks Arenaria verna was seen m its only 

 Perthshire station. The shortest road to Killin was now taken ; and 

 the best plant seen during the descent was Kobresia. 



On Friday Ben Lawers was visited, the ascent being made frpm 

 the west side. The rocky ledges near the top were blue, in many 

 places, with the beautiful alpine forget-me-not, Myosotis alpestri*, 

 while dense cushions of Arenaria sedoides clothed the slopes, alter- 

 nating with equally dense cushions of Silene acaidis, which however 

 was past flowering. Here also were observed Gentiana nivalis, Rhin- 

 anthus Cristagalli var. Drummond-Hayi, Arenaria ridjclla, Draba 

 rupestris, Veronica saxatilis, &c. Still nearer the top, Saxifraga 

 cernua was seen in its only British station ; one or two specimens 

 were in flower. From the top the steep slope was descended towards 

 Loch-na-Cat, and in marshy places near the base several fine speci-
