222 Messrs Gray and Hinxman on [sess. lit. 



Gnaphalium supinum, Sieracium holoscriccum, Ardostaphylos 

 alpina, A. Uva-ursi, Loiseleuria procumhens, Veronica humi- 

 fusa, Oxyria reniformis, Betula nana, Salix herhacea, and 

 Juniperus nxtna. Of the Juncace*, Luzula arcuata, found by 

 Barry in 1833 on Ben More and Foinaven, was obtained 

 on Ben Loyal, and Lnzula spicata, Juneits trifidus, and J. 

 friglumis on Ben ]\Iore. 



With the exception of C. rigicla, from Ben More, no alpine 

 Carex was obtained, though C. rupestris, rarifiora, vaginata, 

 fulva, var. speirostacliya, and piilki are recorded by Watson 

 and Campbell. The alpine Lyoopodiacese include L. alpinum, 

 L. Selago, and Selaginella selaginoides. 



The whole of this district is included in the superagrarian 

 zone of Watson, and consequently many plants of an alpine 

 and subalpine character, such as Silcne acaulis, Sedum BIwdiola, 

 Thalictrum alpinu7n,Alchcniilla alpina, Br aha i7icana,SindBryas 

 octopctala descend to the shore-line; while Buhus Chammmorus 

 and Saitssurea alpina are found respectively as low as 800 

 and 400 feet iibove sea-level. 



The most important discovery made by Mr Gray is the 

 occurrence of Arenaria norvcgica near Inchnadamph. This 

 plant is recorded from Unst, in Shetland ; but Mr Gray has, 

 as far as I am aware, been the first to discover it on the 

 mainland of Britain. 



It remains to notice a few of the more noteworthy plants 

 in the list, which have not been hitherto mentioned : —
