PLANTS OF NORTH SCOTLAND 271 



B. alpestris Fr. 108. t I had long been on the watch for hybrids 

 between B. nana and B. pubescens ; therefore, having found the two 

 growing together in good quantity below Ben Loyal, I made a 

 careful search, which was at length rewarded by the discovery of a 

 plant bearing evident traces of this parentage ; it occurred by a 

 streamlet at just 800 ft. above sea-level. On comparing this with 

 the account of B. alpestris in Summa Veg. Scand. p. 212, I found 

 it to correspond in all respects, except that the leaves were sparsely 

 hairy; oddly enough, the specimen in Herb. Brit. Mus. of Fries, 

 Herb. Normale (which might have well been cut from the same 

 bush), shows the same divergence. The original description is as 

 follows: — " Foliis subrotundis obtuse serratis obtusis glaberrimis, 

 siibtus Iceiibiis, amentis fructiferis peduncidatis erectis, pedunculo 

 amentum iequante, lobis squamarum digitato-trifidis, laciniis 

 dlstantibm porrectis subteqnalibus, nucibus obovatis, ala cinctis 

 latitudinem nucis asquante. B. nana v. intermedia. Hart))}. Vet. 

 Ac. Handl. 1818, p. 148. B. alba v. interm. Wahl. Suec. p. 624. 

 B. humihs HarUn. Scand. 2, p. 228, nee Schrank, Koch. . . . Valde 

 aualoga cum B. inter))iedia Thom. !, sed hsec ad B. alba))i accedit, 

 ut alpestris ad B. r/lutinosani. B. alpestris semper . . . fruticosa 

 est, vix orgyalis, foliis fere B. nance ..." Kegel apparently re- 

 garded B. inteDncdia Thomas as nana x verrucosa ("alba"); but 

 Focke makes them both to be nana x pubescens. In 1886 Mr. 

 F. J. Hanbury and I found a good-sized tree in Glen Oallater, South 

 Aberdeen, which was eventually agreed to by Mr. Bennett as the 

 plant of Thomas, after comparison with an authentic specimen at 

 Kew ; it certainly agrees well enough with the figures in F/. Danlca 

 and in Eeichenbach. In 1887 I came across a second example, about 

 8 or 9 ft. high, near the ferry at Cashil Dhu, Loch Hope, which was 

 slightly nearer to B. alpestris, but hardly separable from the Aber- 

 deenshire plant. As far as Britain is concerned, I think that we 

 may probably consider B. alpestris as B. nana ? x pubescens S , and 

 B. inten)iedia as B. nana ^ X pubescens ? ; the first approaching 

 m.0XQ oXo^Qly to nana, t\iQ ^ecoiidi to pubescens. B. Jiuuiilis Schrank 

 is a true species, and quite distinct. 



Salix cinerea X repens. 108. Ardskinid, Tongue Bay, in two 

 forms; one just intermediate, the other on the repens side. With 

 them grew another bush which appears to be \aurita x repens) 

 X ci7ierea, accompanied by ^S'. aurita x repens (a)nbiyua Ehrh.). — 

 S. phylicifolia L. 111. Linkness, Hoy ; Loch Kirbister, &c.. Main- 

 land. — S. LapponuDi L. 106.* A few bushes were noticed on one 

 crag in the south-eastern corrie of Ben Wyvis. — «S. Myrsinites L. 

 107." Sparingly on Ben Griam More ; both the type and well- 

 marked var. procumbens (Forbes). 



Juniperus co)nuiunis L. var. inter)nedia Nyman. 108.''' By the 

 cave at Ardskinid. "Yes; this looks quite like the Austrian 

 Tyrol plant." — Ar. Bennett in litt. 



Malaxis paludosa Sw. 108. Bog, a little east of Scullomie. 



Epipactis atrorubens Schultz. 108. Near the cave, Ardskinid ; 

 extremely local, but fifty or sixty specimens were seen. Close by 

 we secured a single plant of K. atrorubens x latijoUa,\ which was
