XCiv PROCEEDINGS—PERTHSHIRE SOCIETY OF NATURAL SCIENCE. 
into the sides of rocks which nearly meet overhead, whilst under the 
path a boiling torrent continually rushes. In the Glen itself we did 
not spend much time botanising, being anxious to get to the higher 
ground, and the chief plant of interest observed was Milium effusum. 
On the walls of the Castle of Gloom (otherwise Castle Campbell) 
Parietaria officinalis is abundant. Leaving the Castle, we followed 
upwards the course of the Burn of Sorrow, and, after having gone 
about halfway up, began to meet with some alpine plants. Most of 
the species observed were plants which on the Highland hills would 
not have attracted much attention, but as occurring on the Ochils, 
which possess scarcely an alpine flower, must be looked upon as rari¬ 
ties. Amongst.the first to be found was Saxifraga hypnoides, which 
occurred in far greater abundance than I have seen it elsewhere. 
Soon afterwards Saxifraga stellaris made its appearance, and was 
joined by Epilobium alsinefolium and E. anagallidifolium , Juncus tri- 
glumis , &c. On the drier parts of the banks Galium sylvestre is not 
uncommon, and on the rocks G. boreale is in small quantity. Having 
arrived at the head of the burn, we made our way to Maddy Moss, a 
tract of .peaty ground on the ridge of the hill. From this point we 
had a magnificent view both to the north and south—in the latter 
direction the gigantic cantilevers of the Forth Bridge, rising up like 
miniature hills, attracting attention. On the Moss we found Carex 
rigida, but could not discover Saxifraga Hirculus , which is said to have 
been found here. The botanists mentioned above record Saxifraga 
aizoides from the Burn of Sorrow ; but we did not see that species 
either, and I doubt its occurrence in the Ochils. From Maddy Moss 
we struck in the direction of Ben Cleuch—the highest peak of the range 
—and in a burn found a rare and interesting willow herb which is a 
hybrid, probably between Epilobium montamim and E. alsinefolium. 
Skirting the flank of Ben Cleuch, we descended Tillicoultry Glen, 
gathering on the way Sedum anglicum. From Tillicoultry we took 
the road back to Dollar; on the way there Neottia nidus-avis and 
Scirpus sylvaticus were seen near Harvieston. 
In August another visit was paid to the new railway embank¬ 
ment near Bridge of Earn, and added several additional plants 
to the former list, the most important being Lepidium campestre. 
After going nearly as far as Dron, we explored the narrow plantation 
called Paradise Wood, and found Betonica officinalis in some abun¬ 
dance. We then went by Pitkeathly to the river Earn, and followed 
the south bank up to Forgandenny, observing Saponaida officinalis 
and Spircea salicifolia (both naturalised), Nasturtium sylvestre , and 
Epipadis latifolia. At the Boat of Forgan the best plant of the day 
was found—namely, Stellaria palnstris ,—which is practically a new 
Perthshire plant, though it just enters the county near Stirling in the 
basin of the Forth. Near Forgandenny Station Potentilla reptans , 
Lepidium campestre , and Convolvu/us arvensis were obtained. 
On 28th August we went further afield, and visited the shores of 
the river Forth below Alloa. On this occasion we had the valuable 
assistance, as guide, of the Rev. J. Couper, of Menstrie, who has 
worked up the botany of the district, and who met us at Alloa 
Station. Proceeding first to Clackmannan Pow, a coaling wharf
