30 ANNALS OF SCOTTISH NATURAL HISTORY 



(v.c. 96). A very pretty little specimen was found at Resten- 

 neth, with leaves only ^ to f inch in length, linear-lanceolate. 



f-S. caprea x Lapponum (S. Laestadiana, Hartman, A. canescens, 

 And.) By a waterfall on the Lochsie, at 1750 feet. A well- 

 developed female plant, about four feet high. Fruit very like 

 that of Caprea, but smaller ; style distinct, but shorter than in 

 Lapponum. One of the most beautiful willows that I have 

 ever seen, owing to the satiny pubescence, which extends even 

 to the upper surface of many of the leaves. These are small- 

 sized (as was the case with the form of S. Caprea which grew 

 near), but not more so than in a specimen from Karesuando, 

 Lapland, in herb. Brit. Mus., collected by Laestadius in 1839. 

 In Scandinavia the hybrid is more or less silky, though not 

 nearly so much so as in this Perthshire form; cinerea x Lapponiiin 

 is duller, and more like aurita x Lapponuin. 



S. Caprea x phylidfolia (S. laurina, Sm.) Shee Water ; two bushes, 

 both nearer phylidfolia. 



: -S. cinerea x nigricans (S. strepida, Forbes). Restenneth, 90. When 

 dry, it looks very near nigricans, but cinerea was the more 

 evident parent when living. Barren. 



: \S. cinerea x phylidfolia (S. Wardiana, Leafe). Restenneth, 90. 

 A female plant, just intermediate. 



! S. herbacea x lanata (S. Stephania, B. White). Glen Callater, 92; 

 at about 2700 feet, in the company of both parents. Much 

 like one of Dr. White's Glen Lochay forms. Nearer to 

 herbacea, by its small leaves and decumbent, tortuous habit ; 

 but the leaves are different in colour and texture, woolly at 

 the tips when young, and very evidently reticulate. I notice 

 that herbacea asserts itself in much the same way in Laestadius' 

 specimens of his 5. hastato herbacea (herb. Brit. Mus.) Very 

 probably S. herbacea x Lapponum grows above Loch Kandor, 

 where the two species are abundantly associated. This theory 

 is favoured by the small size, the low and rooting habit, and 

 the structure of some of the leaves ; but I found no fructifica- 

 tion, and cannot be sure that the plant is more than dwarfed 

 Lapponum at present. 



: 'S. herbacea x Myrsinites (S. Sommerfeltii, And.) Head of Glen 

 Callater, 92. Stems prostrate, tortuous, rooting, buried in 

 moss. Leaves small, \ to f inch long, frequently recurved, 

 ovate -lanceolate or ovate -oblong, crenate- serrulate, dotted, 

 shining, more or less hairy on both sides. Bark shining, 

 dark brown ; twigs slender, like those of herbacea. A good 

 intermediate ; probably male, as no catkins were found, though 

 the plant was quite healthy. Close by grew a small bush
