The Scottish Nat? trails t. 



In Perthshire I have seen but six bushes, in five widely 

 separated localities ; but in two of these it was probably 

 planted. In the moss of Restenet, near Forfar, it abounds; 

 but as regards other parts of the district I cannot speak 

 from personal experience. 



3. fragilis L. Throughout the lowlands of the district, but 

 more common in the southern half. Two forms occur — 

 one, the usual British form (var. britannica B.W.), and the 

 other the Continental European form. Of the latter I 

 know of one tree only, near Longforgan in Perthshire. 



S. alba L. Much the same distribution as S. fragilis, but per- 

 haps less abundant, and more frequently occurring only as 

 a planted tree. 



II. Diandrae. 



S. cinerea L., S. aurita L., and S. Caprea L. All common 



throughout the district. 

 S. repens L. Also common, but most abundant on sandy links 

 near the sea. 



3. phylicifolia L. (including S. nigricans Sm., which appears 



not to be really distinct). Common on the banks of rivers 



and on the mountains. 

 S. ArbllSCTlla L. A mountain species, almost or quite restricted 



in the district to the Breadalbane mountains, where it is 



common. 



3. viminalis L. Not uncommon in the lowlands, and often 

 planted to provide material for baskets. 



3. lanata L. One of the most interesting of our willows, since 

 it is a species of Northern Europe only, and does not occur 

 on the mountains of Central and South Europe. Whilst 

 reported to occur in Sutherland, it is really almost restricted 

 in Britain to certain parts of our territory, viz., Glen 

 Callater in Aberdeenshire, Caenlochan and Clova in For- 

 farshire, and Glen Lochay in Perthshire. In the latter it 

 was found long ago, but seems to have been lost sight of 

 till we rediscovered it in two different places some years 

 ago. A curious variety or sub-species (S. Sadleri Syme) 

 occurs in Glen Callater. 



S- Lapponum L. Another mountain species, not uncommon 

 on the higher hills of Perthshire, Forfarshire, and Aber- 

 deenshire. It also occurs at a comparatively low elevation
