" I feel quite certain that this is untrodden ground, for no collector could have left 

 such specimens as we gathered of Draba rupestris ; specimens many times larger than 

 I erer saw before, except some which I found at no great distance on the same ridge, 

 during the last visit which I paid to that district." — p. 21, 



On the south side of Ben Lawers Dr. Greville and Mr. M'Nab found 

 the only specimens of Azalea procumbens seen on the whole range, 

 except those found to the north-west of Milgurdy. Sedum villosum 

 occurred at a much greater elevation than the author had before ob- 

 served it in. Gentiana nivalis was found in considerable abundance 

 at the base of the rocks j and — 



" Among shelving rocks, near the bottom of the hill, and to the eastward of the 

 wood above Finlarig, I gathered Eriophorum gracile. This I think certainly the plant 

 indicated by Don, and figured by Smith in ' English Botany,' and it was even at a 

 distance easily distinguished from Eriophorum angustifolium, among which it grew ; 

 but whether it is entitled to rank as a species is quite another question. I do not think 

 it a scarce plant, at least in the north of Scotland. I am sure I have seen it in large 

 quantities in Sutberlandshire.'' — ^p. 22. 



At Inverarnan Drs. Graham and Greville collected specimens of 

 the oaks which grow there, in the expectation of finding among them 

 the true Quercus sessiliflora, which the former gentleman thought he 

 had seen in that locality on a former visit. — 



" In spite of our receiving a shower-bath with every twig we pulled, we persevered 

 as long as we saw the least chance of clearing up a doubt about the species of this most 

 important genus ; but we were obliged to desist, with only a strong suspicion that my 

 conclusion regarding the sessile-flowered oak was hasty. Whatever character may be 

 got for this supposed species, I fear at present that the foim of the leaf wiU yield none, 

 for I certainly saw trees with leaves which I should have considered characteristic of 

 Quercus sessiliflora, which nevertheless had peduncles several inches long. It was too 

 dark to judge of habit, in which also, in my former visit to this district, I conceived I 

 had seen a character." — p. 23. 



In a second excursion, during a walk by the bottom of Loch Eck 

 to Kilmun, the author observed " nothing worth mentioning except a 

 profusion of Carum verticillatum in almost every damp pasture," and 

 a great quantity of Polygonum amphibium, var. (3. terrestre, in flower. 

 Ben More, the highest mountain in Cowal, the author found to be 

 most unproductive of alpine plants ; this could hardly have been ex- 

 pected, the whole country being micaceous and wet, but an inspection 

 of the district explained the cause. 



" The rocks are not crumbling, but present the same forbidding sharp angles as 

 those we had before seen in Glen Ogle. We got absolutely nothing worth naming in 

 our ascent. We descended by a crumbling ravine in a cliff" where eagles build, and
