354 Botanical Excursions into the Highlands. 



Alisma ranuncvJoideSf 1, 2 — Marshes near Forfar. 



Apargia Tarajeaci, 1. 2. — Frequent on the table-land in the upper district of 

 Clova. I cannot see any good specific distinction between this and A. 

 autumnalis, and I think both pass into the A. alpina, which I found in 

 1825 and 1827 on the mountains in Sutherlandshire, and in the present 

 station last year. 



Arabis petrceoy 1 Near the summit of Ben-na-muic-dui, and at its base, where 



it had been brought by the streams, and where we observed it to have 

 established itself in 1830. 



Arbutus alpina, 1 — Found by Mr Watson on Ben Shith (so written, for some 

 good reason, I dare say, but pronounced Ben Hee), Ben Loyal, Ben 

 Hope, and the moors about Loch ErriboU, in Sutherland ; Ben Nevis, 

 and Cairn Garidh, Inverness-shire; and the hills to the north of Loch 

 Eil, in Argyleshire. 



Astragalus alpimiSy 1, 2 — This was only found in the station where it was first 

 recognised, and seen abundantly last year. The station of Oxytropis 

 campestris was most carefully examined for it by both parties, but not a 

 bit of it was found. Mr Watson is now therefore disposed to think that 

 his belief that he saw it there last year originated in a mistake, and con- 

 sequently we only know one station for the species. 



Carex aquatiliSf Wahl. 2 — Very abundant in bogs on the extended table-land 

 in the upper district of Clova. This Carea; has been many years known 

 in this station, and particularly was first remarked as peculiar in its ap- 

 pearance by Mr Watson in our excursion last year ; but though its cha- 

 racters did not well agree either with C. acuta or C. stricta^ it was hesi- 

 tatingly referred to one or other of these. On our return to Edinburgh 

 this season, Dr Greville found in his herbarium a specimen from Fries, 

 under the name here adopted. It is undoubtedly identical with the 

 Clova plant, and agrees in all material points so well with the character 

 in Flora Lapponica, that I do not hesitate to agree with Dr Greville 

 that thus another Carex may be added to the British Flora. It scarcely 

 ever exceeds a foot and a half in height, and is often much less; where- 

 as Wahlenberg describes his plant as sometimes nearly equalling the 

 height of a man. In lower ground, and in sheltered situations, I enter- 

 tain no doubt that our plant would acquire a much larger size. We ne- 

 ver observed it below the table-land, though it reached the edges of this 

 in almost every direction, filling the bogs in many places with its creep- 

 ing roots, and visible at a distance by its large foliaceous bracteae, rigid 

 slightly curved aspect, and pale green colour. I ought to add, that the 

 plant distributed by the Unio Itineraria, as Carex aquatilis, is altogether 

 different from ours, and seems to me nothing but C. ccespitosa. 



atrata, 1, 2 — Found in great abundance on almost every cliff we visit- 

 ed, particularly on the south side of the Fee, and in Glen Isla. 



pullay 1, 2 — We saw this only in one station, on wet places among 



the rocks on the south side of the Wee. Dr Wight first gathered it, of 

 such unusual size (nearly two feet high), and in all respects having cor- 

 responding proportions, that it was with difficulty I could believe in the 

 identity of the species, though the characters perfectly agreed, till I vi-
