REVISION OF THE BRITISH WILLOWS. 405 



"Willows. The name Salicc Wardiana is, of course, used in a 

 wider sense than that in which it was employed by Leefe. 



The c? has not been noticed, and though it probably occurs, it 

 is very possibly difficult to recognize. 















X Salix ludificans. 



In addition to the Willows just noticed, I have seen specimens 

 from a few bushes, which, whilst undoubtedly very close to 8. 

 ptylicifolia, cannot be satisfactorily referred to that species, on 

 account of their short styles and other peculiarities, which seem 

 to indicate that they are of hybrid origin. The phylicifolia 

 element in them is so predominating that it is difficult to deter- 

 mine the other parent, but after considerable study I think it 

 must be S. aurita. Since S. aurita flowers a little later than the 

 other Caprece, it might be imagined that hybrids of it with the Phy- 

 licifolim would be at least as frequent as those of the other Caprece ; 

 but this is either not the case, or they have been overlooked. 



For this hybrid I propose the name 8. ludificans. As already 

 indicated, all the specimens I have seen are very much nearer 

 phylicifolia than aurita, though, judging from other hybrids, 

 tt is probable that forms more remote from pliylicifolia occur. 



Ine specimens and some of their distinguishing characteristics 

 are as follows : 



A bush found by Mr. 0. M'Intosh on the banks of the Tay 

 above Dunkeld has the catkins (?) quite intermediate between 

 Phylicifolia and aurita ; but the leaves are very near those of 



e forrr ier species, exhibiting, however, in their shape a sug- 

 gestion of aurita. The scanty pubescence, moreover (present 

 °u some of the leaves only), shows an affinity with aurita, since 



e hairs are finer and softer than in phylicifolia and slightly 



crisped, 



e other specimens I have seen were collected in Caithness 



y Mr - J. Grant and sent to me by Mr. A. Bennett. The 



Samples are, unfortunately, not in the best condition and the 



Material is scanty. They represent three bushes, of which one is 



* and two ? • One has the catkins ( $ ) rather different from the 



J ^-mentioned Perthshire plant, but, like it, intermediate 



J** ween its supposed parents, and has the young leaves (I have 



seen mature ones) apparently also intermediate. Another 



ears a 8t riking resemblance to some forms of the hybrid between
