42 TRANSACTIONS AND PKOCEEDINGS OF THE [Sess. lxv. 



expected that a stranger to the country woulrl be able 

 to add much to what had already been recorded. 



The first day was an unfortunate one. I accompanied 

 a party which had for its aim the investigation of the 

 ground between Beinn Heasgarnich and Craig Mhor, but 

 our work was brought to an end by thick mist and heavy 

 rain, and, to my disappointment, I had only a very short 

 time among the crags of the latter mountain. I brought 

 away, however, a specimen of the rare Aulacomnium turgi- 

 dtmi, which was growing among Hypnum sarmentosum at 

 the foot of the crags. This is one of the few habitats for 

 Leptodontium recurvifolium, whicli I was not fortunate 

 enough to meet with. 



Craig Chailleach, and the neighbouring Ben Cruban, 

 were more accessible, and here I found most of the plants 

 for which these hills are noted, including — Plagiothecium 

 Mullcri and Thuidium Fhiliherti — both recently added to 

 our Flora by Mr. H. N. Dixon ; Plagiothecium striatellum, 

 Thuidium hystricosum (rare, I believe, in the North, 

 although a very common moss on the chalk hills of 

 Kent and Surrey) ; Plagiobrgwn de^nissum (plentiful, 

 and in beautiful fruit, on the top southern ledges of 

 Chailleach) ; Hypnum trifarium, H. hamulosmn, and 

 II. rugosum ; Gynodontiwm virens, var. serratum ; Mniiitn 

 cinclidioides, and Sp)laclinuvi vasculosum. Ortliothecium, 

 rufesceyis, although very abundant on dripping rocks on 

 all these hills — a rare sight for southern eyes ! — was 

 not found in fruit. 



Two visits were paid to Ben Lawers, and the best 

 plants found here, out of many uncommon ones, were — 

 Eurhynchium cirrosum, Brachythecium plicatuyn, Hypnum 

 Halhri (in fair quantity), Blindia cccsjnticia (its only British 

 habitat), Barhula ruhdla, var. ruherrima ; Amhlystcgium 

 curvicaide, var. strictum ; Hypnum Bamhergcri, H. calli- 

 chi'oum, and H. ardicum. The last, a rare plant, was 

 abundant in the stream which runs down the western 

 slope of Beinn Ghlas, hanging from the edges of rocks in 

 the small waterfalls. 



On the margin of Lochan-iia-Lairige, I got Sphagnum 

 Austini, Sullivant (;S'. imhricatum of Warnstorf), which I 

 also found on the southern slope of Meall-nan-Tarmachan.
