REVTSTON OF THE BRITISH WILLOWS.

style is about as long as the naked young ovary ; the yellow 

 stigmas are bifid and spreading, and half as long as the style ; 

 the nectary and the pubescent pedicel of the ovary resemble 

 those parts in Salix lanata. 



8. Sadleri has been supposed to be a hybrid of 8. lanata and 

 8. reticulata ; but after long and repeated study of both wild 

 and cultivated specimens, 1 cannot recognize in it any trace of 

 S. reticulata, nor of any species but S. lanata, a remarkable form 

 of which I think it must be considered to be. 



Serrate leaves are not common in S. lanata, though Anderson 

 mentions their occurrence, and I have seen examples. Moreover, 

 in S. Sadleri the serration is obscure and not constant. The chief 

 differences lie in the small catkins and in some parts of their struc- 

 ture, but even in these the lanata element is preeminent. The 

 whole facies of the plant is that of a small form of 8. lanata.

X Salix supehata, n. hybr. (S. lanata x S. reticulata.) 



A willow which grows, in company with S. lanata and other 

 mountain-species, on the rocks at the head of Allt Innis Choarach, 

 Glen Lochay, Perthshire, has required a considerable amount of 

 study to decipher. At first sight the facies of it does not distinctly 

 suggest any particular affinities ; but on examination, and keeping 

 in mind the species with which it is associated, a clear relationship 

 to S. lanata is revealed. The other parentage seemed very difficult 

 to guess, but a certain uudescribable appearance of the plant 

 hinted that it might be found in S. reticulata. The possibility of 

 this suspicion being correct further study has made a probability. 



The following description is taken from dried specimens : 

 A very low bush, with erect or ascending branches ; stems rather 

 stout, twigs moderate. Bark rich brown, rather shining ; young 

 shoots greenish, sparingly hairy, but soon glabrous. Buds shortly 

 oval-oblong, obtuse, at first greenish and very slightly hairy, then 

 pale brown and glabrous. Leaves more or less obovate, base 

 attenuate and often unequal, apex shortly pointed and plicate- 

 twisted ; leaves at the top of the shoots the largest (average size 

 about 1^ x | of an inch), those below smaller and proportionately 

 narrower ; upper surface yellowish green, scarcely shining, flat, 

 with slightly impressed veins ; lower subglaucous dull, with the 

 chief veins conspicuously raised and reticulate ; upper surface 

 lightly woolly with short hairs, under with long and short hairs,
