150 NOTES ON HIGHLAND PLANTS. 



I am extremely indebted to Messrs. Arthur Bennett and Beeby, 

 who have given me the benefit of their knowledge of many critical 

 forms, besides sending doubtful forms for determination to Prof. 

 Hseckel, Dr. Buchenau, and Dr. Lange. My thanks are also due 

 to Mr. F. J. Hanbury, who kindly looked through the Hieracia, 

 Prof. C. Haussknecht, Dr. Buchanan White, Prof. A. W. Bennett, 

 and Mr. H. N. Bidley. 



The nomenclature is usually that of the ' London Catalogue,' 

 ed. 8. * denotes a "new county record"; t a form apparently not 

 known before as British. 



Ranunculus Flamtnula L., var. radicans Nolte (pseudo-fluitans 

 Syme) occurred in Lochan-na-Chait, Ben Lawers (88). The 

 extreme specimens resemble a plant from Littlesetter Loch, 

 Shetland, but differed greatly in appearance, when fresh, from 

 Swiss R. reptans L., and are considerably coarser than my Loch 

 Leven example. It shaded off gradually towards the type. 



Caltha palnstris L., c. minor Syme, was still in good flower on 



Cam Liath (89) on Sept. 19th. 



*Arabis petrcea Lam. Stob Ban, Mamore Forest (97), at about 

 2500 ft. The glabrous form ; leaves broader and less deeply cut 

 than in the Aberdeenshire plant. 



Cochlearia officinalis L. Fruiting plants from Ben Lawers, Ben 

 Nevis, and Stob Ban show scarcely any venation of the pods, even 

 when dry, and seem to me different from the Teesdale "alpina" 

 which is distinctly veined. 



Viola sylvatica Fr. A very dwarf and compact form occurs on 

 the limestone hillocks about Durness (108) ; something like it 

 grows on Cronkley Fell, N.W. Yorks. 



*Polygala serp tjllacea Weihe. Abundant near Altnaharra and 

 Inchnadamph (108). 



*Cerastium arcticum Lange. The " C: latifolium var. Smithii" of 

 Ben Lawers (88) is, I think, clearly this, after comparison with the 

 Cairntoul plant. I failed to get it in fruit. There are specimens 

 of it in the S. Kensington herbarium from Snowdon, Ben Lawers, 

 Ben Hope, and Ben More of Assynt. Is the specimen figured in 

 Smiths E. B., and preserved there, the same plant? Seeds from 

 Aberdeenshire do not appear to differ appreciably from those of the 

 Shetland var. Kdmonstonii. — C. alpinum L., b. pubescens- Syme. 

 What I suppose to be this was gathered on Ben Nevis (97). I have 

 not yet seen type -specimens. 



Armaria sulcata Schlecht. On the summit of Ben Lawers this 

 was just like the Shetland "forma condensate"; lower down it was 

 more luxuriant, but the variation was not marked. — *A. sedmdes 

 Schultz is plentiful on both sides of Ben Klibreck, and should 

 therefore be recorded for 107 as well as 108. 



Sagina nivalis Fr. In advanced fruit the pedicels are certainly 

 not "always erect," as stated in the books. On Aug. 24th nearly 

 all were decumbent, and the plant greatly resembled small states 

 of S. maritima in appearance. — *S. nodosa E. Mey. Near Durness 

 (108). It ascends to fully 2000 ft. above Lochan-na-Lairige (88). 



Ilex aquifoUuw L. is clearly native about Inchnadamph, growing
