of many of the wells and pools were caked, and the 

 best streamlets looked as if water had not run in 

 them for months. 



The following are some notes on the principal 

 alpine plants observed : 



Arabis petrcea, Lain., var. hispida, DC. — The form 

 which occurs not uncommonly on the Breadalbane 

 range must be referred to this variety. The 

 distinction between it and the typical A. petrcea 

 can be best seen when the plants are growing. 

 I have gathered specimens of the latter, which is 

 perfectly glabrous, in the Island of Midi. 



Draba incana, L. — Very abundant, and in good 

 condition. 



JD. rupestris, R. Br. — This plant appears to be getting 

 rarer, but the dry weather of June may partly 

 account for its disappearance. 



JErophila inflata, Hook. — Certainly spreading. I saw 

 more dried stems and remains of stronger plants 

 than I had ever seen before. After carefully 

 sowing all the seeds left in the dried pods, I 

 removed all traces of the plant for this year. 



Cerastium alpestre, Lindbl. ) In good flower, although 

 C. lanatum ("Lam."). /-the plants were very 



C. pubescens, Syme. J small. 



Arenaria sulcata, Schleeht. (A. rubella, Hook.) — In 

 very fine condition. 



A. sedoides, Schultz. — Also in fine condition. 



Sagina Linncei, Presl. — I am not at all sure that our 

 knowledge of this plant is completely satisfactory, 

 as I have frequently observed that S. procumbens, 

 S. nivalis, and S. subulata seem all to grow 

 mixed with S. Linncei in places where the last- 

 named is plentiful. 



S. nivalis, Fr. — I am fully convinced that I was right 

 in supposing that the snow in 1884 had nearly 

 killed this plant in its favourite station on Ben 

 Lawers. It is reappearing, however, but is much
