88 TRANSACTIONS AND PROCEEDINGS OF THE (Sess. xxix. 
cernua, found in this country only on the top of Ben Lawers ; 
of the latter method, Polygonum viviparvm is a common 
example. Poa alpina, a rare grass, is generally viviparous. 
Canness Glen is a branch of Caenlochan. Their united 
streams form the river Isla. JLactuca alpina has been 
recorded from Canness, but I have never visited it. A mile 
or two farther east is the knoll called Little Culrannoch, at 
the head of Glen Doll, where the rare Lychnis alpina is 
associated with the sea-side plants, Armeria maritima and 
Cochlearia officinalis, 
Due north from this, and on the other side of the water- 
shed, lies Corrie Ceanmor, whose loch drains into Loch 
Callater and thence into the Dee. It is impossible to do this 
Glen and Caenlochan in one day—to Corrie Ceanmor and back 
is about twenty-four miles. We are now in Aberdeenshire, 
and the rocks are granitic. They are very precipitous. Flower- 
ing plants are scarce. Swussurea alpina grows luxuriantly on 
some of the ledges. Thalictrum alpinum and Rubus saxatilis 
are plentiful, and there are a number of willows—myrsinites, 
reticulata, and lapponum, lanata perhaps being the most 
noteworthy. The Cyperacee are more common, as Carex 
vaginata, atrata, panicea, capillaris, and rupestris, the rarest 
of all) Many years ago Sadler found Carex frigida, and I 
suppose it has been found by no one else. Last year we 
spent an hour or two looking for it, without success. I have 
seen Sadler’s specimen in the Botanic Garden herbarium 
here. I am not in a position to say whether it is a good 
species or not; but I have gathered plants of binervis, which 
very closely resemble it in general appearance. Juncus li- 
and tri-glumis frequently occur; castanevs has also been 
recorded, but I have not come across it here. There is a 
large quantity of the parsley fern growing among the debris 
of one of the screes. The holly fern and the green spleen- 
wort are plentiful everywhere ; and on many of the grassy 
ledges the moonwort may be seen, as well as Athyrium 
alpestre,on the slopes. Saxifraga hypnoides—a common plant 
on our rockeries—has its home high up on the rocks; and 
festoons of oppositifolia are on every hand, though blooms 
are generally scarce in the month of July. The variety 
Drummond-Hayi of Rhinanthus Crista-galli, named by Dr. 
Buchanan White after his friend, is also found here.
