being just visible), and also commanding the full length of Loch 
Lomond. On the occasion of the Society’s visit, although the day 
was fine, a dense white mist obscured the view of the surrounding 
mountains, but the beauty of the landscape was still sufficiently 
evident. The yellow mountain saxifrage (Saxifraga aizoides, L.) 
was seen on the banks of the streams in fine bloom, and other 
plants of interest observed were the rose-root (Sedum Rhodiola, 
L.), the stone bramble (Rubus saxatilis, Z.), and the lesser 
club-moss (Selaginella selaginoides, Gr.). 
On 8th April, tg01—the Glasgow Spring holiday—an excursion 
to Ardlui (head of Loch Lomond) was arranged with the object of 
ascending Ben Vorlich. Rain falling heavily throughout the day, 
the greater number of the party abandoned the idea of making the 
ascent. Six members, however, attempted the mountain, three of 
whom succeeded in reaching a small cairn at an altitude of 2,600 
ft., at which point the further ascent was abandoned. Snow was 
encountered at an altitude of about 1,500 ft., all above that limit 
being covered to a considerable depth, rendering the search for 
alpine plants impossible. ‘The wind was very high, and the snow 
was being driven in great clouds, rendering progress difficult. 
Owing to the heavy rain the streams were all in flood, and the 
numerous waterfalls in the district were seen to great advantage. 
The rocks and banks on the lower slopes of the mountain, and 
especially the wooded glen of the stream above Stuckindroin, were 
found to yield a rich moss-flora. Particularly striking were the 
great quantities of the beautiful Aypuum Crista-castrensis, L. 
The filmy fern (Aymenophyllum Wiéilsoni) was found very 
abundant. Specimens of the rare fungus, Dedalia quercina, were 
found in the woods below Ardlui.
