234 NOTES ON HIGHLAND PLANTS. 



Betula odorata Beclist. {glutinosa Fr.), var. parvifoUa (Wimm.) 

 Kegel. So Dr. Lange names specimens from Stob Ban (97), Clach 

 Leathad ("98), and the stream descending from Ben More towards 

 Luib ('''88). All these agree well in leaf-characters with Keichen- 

 bach's figm'e of sudetica, which is a synonym; the leaves are 

 strongly cuneate below. They differ widely in appearance from the 

 Loch Hope plant which Dr. Lange determined to be this, "going 

 off in the direction of B. aljiestris.'' But the last-named seems to 

 Prof. Babington rather a form of B. intermedia, of which, un- 

 fortunately, I have seen no very satisfactory specimens. It 

 certainly looks much nearer to Reichenbach's figure of intermedia 

 than of sudetica, and approaches closely to the Glen Callater tree 

 found by Mr. Hanbury and myself in 1886. I carefully compared 

 them both with the plate, and do not see why the name should not 

 stand. Prof. Babington is one of the few British botanists who 

 have seen B. intermedia growing in quantity. He also refers to it a 

 specimen from the N.E. slope of Stob Ban (97), w^ith more elongate 

 leaves, deeply and rather distantly serrate-toothed. — f Var. car- 

 pathica (Wald. & Kit.) Kegel. Streamlet in Glen Nevis (97); 

 stream on the Luib side of Ben More (88) ; ledges on the S. side of 

 Glen Fiagh (90). Also determined by Dr. Lange, and seeming to 

 correspond with Reichenbach's figure. The leaves are mostly 

 broad-based, not cuneate below, shining on their upper surface ; 

 buds resinous ; bark nearly black ; branches tortuous, whereas 

 those of var. ]jarvifolia are straight. I was too early to get mature 

 catkins. Probably both these forms will prove to be common 

 enough. The study of our birches has hitherto been much neg- 

 lected, owing to the difficulty of getting them properly determined. 

 — *i>. nana L. Moorland by Lochan Mathair Etive, Kingshouse 

 (98), at a height of only 970 ft. above sea-level. 



Salix aiirita L., b. minor Sonder. Stream descending from the 

 E. side of Ben More, above 2000 ft. : associated with a beautiful 

 dwarf form of S. pJujlicifolia, probably var. Davalliana. — S. Lap- 

 p)onwn L. Streamlet on Clach Leathad (98). In the ' Student's 

 Flora' it is mentioned as growing in Argyle, but that is not one of 

 the counties enumerated for it by Watson. — b. Stuartiana (Sm.) 

 appears to be little less common around Clova than the more 

 general form arenaria. — -S'. cinerea-repens Wimm. Dr. Buchanan 

 White thus names a willow from the coast at Melvich, W. Suther- 

 land, found in 1886 by Mr. Hanbury and myself, and referred at 

 the time to a very large-leaved state of repens. — S. Myrsinites x 

 nigncans is another identification of his. I believe the locality to 

 have been Corrie Ceannder, S. Aberdeen ; but the specimens have 

 not yet returned to me. Mr. Arthur Bennett had suggested this 

 name for a plant from thence, some time back. — iS. herhacea x 

 Lapponum. Cliffs of Glen Fiagh (90). This conclusion was arrived 

 at independently both by Dr. White and myself. I have just learnt 

 from the Rev. E. F. Linton that he and his brother had twice pre- 

 viously gathered, in a neighbouring corrie, what appeared to them 

 to be the above hybrid, though it had never been positively ascer- 

 tained, owing to insufiicient material. I believe that I saw several
