356 Botanical Excursions into the Highlands. 



tance on the same mountain. It grows on a bare, dry, stony summit, 

 or in the edges of the immediately adjoining peat, at an elevation which, 

 judging from the heights ascertained by Mr Watson, I suppose may be 

 about 3200 feet above the sea. The rock in both stations is a mixture 

 of felspar and talc, is much weathered, has a deep cream colour, and is« 

 quite different from any thing around. We observed that in the same 

 spots grow Armeria vulgaris^ Cochlearia officinalis, and Cherleria sedoidesj 

 and there only at this elevation. A shepherd whom we met upon the 

 ground told us he had seen the plant growing on a mountain top, either 

 between the Glen of the Dole and Bachnagairn, or between this and 

 Lochnagar, I am uncertain which, because, as he evidently did not dis- 

 tinguish between the Armeria and Lychnis, I paid little attention to his 

 report at the moment ; but reflecting since on the one never having 

 been seen without the other on these mountain tops, I think the shep- 

 herd's accuracy should have been inquired into. The capsule of Lych- 

 nis alpina is defined as unilocular. Our plant, which is certainly that of 

 Linnaeus, as I learn from Mr D. Don, who has compared it with the 

 Liinnean herbarium, is most distinctly 5-locular when far advanced to 

 ripeness. Whether the dissepiments ultimately disappear, whether the 

 Swiss plant is in this respect different from ours, or whether the des- 

 cription of its capsule be incorrect, I am unable, from want of ripe fruit, 

 to determine. 



Malaxis paludosa, 1, 2 — This we found in many situations, and in large 

 quantity, in the bogs and by the sides of the rills in the valley of Clova, 

 or a few feet up the mountains on both sides. 



Molinia depauperata, 2 Extremely vigorous, and in large quantity, on the 



cliff near the Oxytropis campesiris. 



Nasturtium terrestre, 1, 2 Not a common plant in Scotland, but found by 



the first party near the Loch of Forfar, and by Dr Wight near Loch- 

 leven. 



Nupliar pumila, 1 In various stations. 



Poa alpina, 2 In large quantity in Glen Isla, and not in a viviparous state. 



Potentilla alpestris, 2 Widely distributed on the rocks to the south of the 



Fee, and in Glen Isla. 



Primula scotica, 1 Found by Mr Watson in various stations from Thurso 



to Farr. Some of the specimens have several long single-flowered scapes, 

 the same variety of form which separates Primula vulgaris from P. elatior. 



Pyrola rotundifolia, 1, 2 — ^Very sparingly in Glen Dole. 



secunda, 1, 2.— Much more common than the last on rocks in various 



places in Clova.. 



Salic lanata, 1, 2 Both male and female plants in great perfection on many 



rocks in Glen Dole, Glen Isla, and Glen Callader. 



rosmarinifoliaf \ Probably from the same bush as that seen by Dr 



Greville two years ago, and in no better condition. 



Saxifraga ctsspitosa, 1 Picked by Mr Barry, but sparingly, in the same si. 



tuation as that in which it was seen by him last year. 



— niv(^is, 1, 2 In tolerable quantity in Clova, but much more abundant- 

 ly, and in better condition, in Glen Isla. 



Salix rivularis, 1 On the old stations on Lochnagar and Ben Nevis.
