places, and if not native, is at least thoroughly well- 
established. In a damp wood great masses of the broad¬ 
leaved bellflower (Campanula latifolia) were very con¬ 
spicuous, the tall erect stems with their large blue or white 
bells being very handsome. The white-flowered form was 
nearly as abundant as the normal blue one. In a ditch a 
large bed of a plant that is very local in Perthshire—the 
bladder sedge (Carexvesicaria) was growing abundantly. A 
considerable quantity of this plant was seen in the course 
of the day, so that it is really more abundant in the county 
than was thought to be the case. 
A marsh near Tayfarm produced a number of interest¬ 
ing things. The rarest of these is the great water-dock 
(Rumex hydrolapathum), a very handsome species 4 or 5 
inches high. This species is confined to three or four 
localities in Perthshire. Along with it the Spear-wort 
(so-called from the state of the leaves), a kind of buttercup 
with large yellow flowers, grew in considerable masses; 
while the dark green leaves and chocolate brown heads of 
the mace-reed (Typha latifolia) filled the centre of the 
marsh, and formed an admirable background for the other 
plants. 
A laige shingly field, called the Inch, was next visited 
and was found to be equally productive, but of course of 
quite a different class of plants. The greater or less 
abundance of the sea campion (Silene maritima), sea thrift 
(Armeria maritima), and sea rib grass (Plantago maritima), 
gives these shingles the aspect of a sea-shore. Amongst 
them grew several local species, such as Teesdalia nudi- 
caulis, which is very rare in Perthshire; Sagina subulata, 
and S, nodosa. In addition to these large patches of a 
stone crop, probably Sedum rupestre, grew abundantly 
amongst the stones. This plant is not admitted as a 
Dative of Scotland, and is most likely an accidental intro¬ 
duction in this place; but, wherever it has come from, it 
is now well established. Like the lupin (Lupinus per- 
ennis), which was seen in abundance, the stone crop in 
question has probably been brought down by the river 
from some garden. 
The river bank was next explored and produced another 
rare Perthshire plant, Astragalus glycyphyllus, along with 
some others of less rarity, such as Calamintha clinopodium, 
Origanum vulgare, and Malva moschata. In a sandy field 
some perplexing forms of the creeping Tormentil were 
found. Possibly these may be Potentilla mixta. 
In the old course of the river near Delvine several good 
things were discovered. The best of these was Poly¬ 
gonum minus, which here reaches its most northerly point 
(so far as is known) in Britain. The discovery of Subul- 
aria aquatica in one of the “ backwaters ” was a surprise. 
This little white-flowered water-plant is not uncommon in 
the Highland lochs, as well as in those near Dunkeld and 
Blairgowrie, these lochs being all either on the Silurian 
formation or on the Conglomerate, which lies close to it. The 
pool in which it was found at Delvine is on the Bed Sand¬ 
stone formation, and, so far as is known, is the only spot 
on that formation in Perthshire where it occurs. The 
other plants found here were Peplis portula, Apium 
inundatum , &c. 
After this nothing very remarkable was found, and the 
party, proceeding to Caputh Ferry, crossed to Murthly 
Station and dispersed.

8. Excursion to Longforgan and Invergowrie. 
This, the last excursion of the season, was fairly well 
attended. Starting from Longforgan Station, the party 
proceeded to examine the Huntly Burn or Pow in its 
lower course. A number of interesting forms of willows 
were observed here, some of them being kinds which had 
not been seen in other parts of the district. Where the 
burn joins the Tay various maritime plants began to make 
their appearance, such as Scirpus maritimus, Aster tri- 
folium, &c. Also specimens of a sedge that is rare in 
Perthshire—Care* vulpina. Along the shores of the Tay 
various other maritime plants were noticed, but none of 
any particular rarity. The various quarries near Kin- 
goodie were examined with interest and profit. Amongst 
the plants found here were Ranunculus confusus, R . 
sceleratus, Malva sylvestris, Senecio viscosus, Sedum re- 
flexum, Rumex crispus var. trigranulatus, &c. Several 
mollusks were also obtained, including Helix aspersa 
(which is local and rare in Perthshire), H. nemoralis in 
several forms, H. hispida, and Succinea sp. Nearer Inver- 
gowrie Station some other local plants were seen, such as 
Potentilla replans, Fumariadensiflora, and, as an “escape,” 
Linum usitatissimum. After spending a short time in 
inspecting the ruins of Invergowrie Church the party
