DR. P. BUCHANAN WHITE'S 



the British descriptions of the plant generally indicate. The 

 leaves vary a good deal in size ; in shape from suborbicular to 

 oblong-obovate ; and in the amount of pubescence from being per- 

 sistently woolly to nearly quite glabrous almostfrom the beginning. 

 The catkins vary in size and in the colour of the pubescence of 

 the scales, which, though usually yellow, sometimes fading to 

 grey, is occasionally grey from the first. * 



Andersson describes several modifications, but there are none 

 which deserve varietal rank. 



Salts lanata seems almost confined (in Britain) to Forfarshire 

 and Aberdeenshire, or at any rate is most common in these 

 counties. "Whilst recorded long ago from Perthshire, it seems to 

 have been lost sight of there till recent years, when it was redis- 

 covered by Messrs. Brebner and Haggart and myself in a few 

 places in the Glen Lochay hills. 



Var. Sadleri (Boswell-Syme). 

 The plant described by Boswell-Syme as Salix Sadleri has now 

 been in cultivation for several years, and has developed some 

 features not seen in the original wild specimens. The stems have 

 increased m thickness and become tolerably stout ; the leaves have 

 become larger (some being 1} x 1* inch) . Many of them are more 

 decidedly cordate at the base, and many are also furnished with 

 large ovate-acute glandular-toothed stipules. Though the margins 

 of the leaves were described as entire, yet even in the original 

 specimens the edges of some of the leaves are, more especially 

 towards the base, very finely glandular-serrate or crenate, the 

 teeth, however, being almost reduced to glands. In mature 

 leaves the margin is recurved or thickened. The catkins, which, 

 so tar as I have seen, have not increased much in size, may 

 be described as either terminal or as terminal and lateral, 

 according to the view taken of the structure of their peduncles, 

 they are situated at the end of shoots winch have two or three 

 leaves These shoots might be considered to be leafy peduncles, 

 out as their leaves are furnished with stipules and have buds in
