362 Plants observed by Dr Graham during 



Lvxulu arcuata. — Summit of Ben-na-muicdui abundantly. 



Lycopodium annotinum. — Very abundant on all the mountains in the Ben-nn- 

 muic-dui range, and on the ascent to Loch-na-gar from the north. 



Oxytrofts campestris In the old station near the Glen of the Dole in great 



abundance. 



Phleuuv alpinum On Ben-na-Buird, most abundantly ; in the corry at the 



head of Glen Callader ; and on Loch-na-gar. 



Poa alp'ma ririprtJ-a.— Ben-na-Euird. 



Polytrichum hercynkum. — Ben-na-muic-dui, abundantly. 



Polytrichum septeutrionale In profusion, and in fine fruit, on Ben-na-Buird 



and Ben-na-muic-dui. Drs Hooker, Greville, and Mr Arnott found this 

 S])ecies in fruit for the first time in Britain on the latter mountain in 

 1822, but very spax-iugly. It was never seen in Britain in such perfec- 

 tion and abundance as we now noticed it. 



Pyrola rotundifolia, — very abundant in the woods on the Dee. 



Pyrola secunda, — among the heath in the ascent to Loch-na-gar from the north. 



Rubus snberectus. — Clova. 



Salix arenaria, — in very considerable variety, head of Glen Callader ; Loch- 

 na-gar ; banks of the Esk, Clova. Among the varieties we certainly have 

 S- Stuartiana of Eng. Bot. ; but it gives me pleasure to think that we 

 have many memorials of the late excellent minister of Luss, less fleeting 

 than the sjiecific name of a willow. 



Salix Jierhacea, var. major Corry at the head of Glen Callader. This variety 



is not generally known, but is not uncommon. We have it in the Bota- 

 nic Garden, brought from mountains of Sutherlandshire in my excursion 

 with the botanical pupils in 1827. Dr Hooker remarks most justly, that 

 the common variety is not " so small as is generally supposed, for its 

 stems divide and creep below the surface of the earth, scarcely rising an 

 inch above ;" but after cultivation in the Botanic Garden, this variety 

 has acquired a woody stem, prostrate upon the surface of the ground, from 

 2 to 3 feet long, and nearly as thick as the little finger. "VVe have in cul- 

 tivation the common variety, and we have another also from the moun- 

 tains of Sutherland, with upright shoots, but both are much smaller than 

 the variety to which I now allude, and neither ever acquire the large 

 prostrate stems. 

 Sulix lanata — Corry at the head of Glen Callader. This is the second sta- 

 tion for this willow in Britain ; but it is at no great distance from the 

 first, in Clova. 

 Saxifraga rivularis, — in profusion on Loch-na-gar. 



Saxifraga ctespilosa. A single tuft only, the first that has been found in Scot- 

 land, was picked by Mr Macuab on Ben-na-Buird. 

 Sonchus cceruleus.^Spaxingly in the old situation on the White Water. Five 

 of the party only reached the spot, and one specimen for each was all 

 that was found. The plant maintains itself by its perennial roots, but 

 shows no tendency to diffuse itself by seed. 



Slellaria cerastoides Ben-na-Buird ; Ben-na-muic-dui. 



Subularia aquatica. — Loch in Glen Callader. 



Veronica alpina Corry at the head of Glen Callader ; Loch-na-gar ; Ben-na-
