ferent ridges of the mountains, and found in drier situations than 

 D. incana usually inhabits. July. 



Melampyrum sylvaticum. Burn above Finlaria; : very sparinoly. Au- 

 gust. 



Dry as octopetala. Rather plentiful upon Craig Calliach. July. 



Arbutus Uva-Ursi : usually found upon rocks and broken places in 

 subalpine situations : upon Mael Ghyrdy it is plentiful upon the 

 ground, intermixed with Vaccinium Vitis-Idcea and V. MyrtUlus. 

 May and June. 



Cherleria sedoides. Ben Lawers, Mael Greadha. June, July. 



Calyx one-leaved ? yet deeply divided into five segments. Stamens 

 from a glandular disk : those opposite to the segments have, on 

 each side of their base, a yellow gland (not " on the inner side") ; 

 the other filaments are placed between these lateral glands, not 

 at their back. 



Arenaria verria. Mael Duncrosk : a very small distance from Craig 

 Calliach; where, at nearly the same elevation, A. rubella occurs, 

 and where A. verna is not found. 



Filaments from a glandular disk ; those alternate with the petals 

 have at their exterior bases a single nectariferous pore. 



A. rubella. Mael Greadha, very sparingly : rather plentiful on the 

 east side of Craig Calliach, at a considerable distance below the 

 summit of Ben Lawers, towards the south-west, in considerable 

 plenty : it prefers the bare declivities at the foot of projecting rocks 

 thinly covered with soil. July. 



Anthers generally quite white. Nectary very similar to that of 

 Cherleria. Styles 3, 4, or 5 ; frequently 4. Stem sometimes two- 

 flowered, mostly single-flowered. 



Sedum villosum. Ben Lawers, very sparingly, near the sources of 

 rivulets halfway up the mountain. June. 



Spergula saginoides. Craig Calliach, Ben Lawers, Sec. not uncom- 

 mon. July, August. 



Vaccinium uliginosum. Craig CaUiach, upon the rocks in wet situa- 

 tions : on Ben Lawers it is found with V. Myrtillus, halfway up 

 the mountains. June. 



Epilobium alsinifolium. On the east side of Mael Greadha, below the 

 rocks ; not observed elsewhere : E. alpinum very common. July.
