mountaiu which had not heen previously botanised by the 

 Club. On the way up to the corrie they found Kohrcsia 

 caricina, Willd., on the well-known station for this plant, 

 which is a very different part of the mountain from the 

 place where the plant was found by the Club two days 

 previously. They did not enter the great corrie, but at 

 once proceeded to examine the rocks to the south of this 

 corrie. Among the plants collected may be mentioned Arahis 

 petrcca, Lamk. ; Drdba incana, L. ; Dry as octopctala, L. ; Saxi- 

 fraga nivalis, L. ; nicraciuin lingulatum, Backh. ; II. vulgare, 

 Fries; H. Iioloscriceum, Backh.; H. Oreades, Fries; Veronica 

 humifusa, Dicks. ; Bartsia alpina, L. ; Carex vaginata, Tausch. ; 

 Asplcnium viridc, Huds.; and the moss Lcskca riifesccns. The 

 Hicracia were indentified by Bennett, of Croydon. A very 

 curious form of Arahis was obtained on the rocks, which 

 differed much from the ordinary form of Arahis pctrcca. The 

 plants were all seedlings, and they are being cultivated with 

 the view of identifying the species. These plants were 

 sent to Bennett, and he has planted some of the specimens, 

 and if the plant flowers we will ascertain whether or not 

 it is a mere form of Aixihis petrcca. 



The day was remarkably fine, and the party went in the 

 afternoon to the summit of the mountain, from which they 

 had a magnificent view of the surrounding country. 



The other party crossed the river by the bridge at 

 Coninish farmhouse, and went to Ben Oss, a mountain not 

 previously examined by the Club. It is 3374 feet high, 

 and is situated south-west of Beinn Laoigh. We found the 

 rocks very unproductive. We saw many of the more com- 

 mon alpine plants, but only those which are found on almost 

 all our Highland mountains. The best plant observed was 

 Saxifraga nivalis, L., and even this plant was rare. It was 

 very difficult climbing among the rocks, but we all reached 

 the top in safety, from which an excellent view was obtained. 

 We were anxious not only to examine the mountain, but 

 also Loch Oss, a small loch situated due east from the 

 summit of Ben Oss. It is 2084 feet above sea-level, and 

 the river from it runs into Glen Falloch, a short distance 

 above the head of Loch Lomond. The loch, like the moun- 

 tain, w^as somewhat disappointing. The two best plants 

 obtained were Callitriche hamulata, Kiitz., and Potamogdon
