REVISION OP THE BKITISH WILLOWS. 385 



also under Salix cinerea, Smith's own specimens of S. oleifolia 

 are possibly hybrids of aurita and cinerea, but will have to be 

 compared with authentic examples of lutescens. 



In Perthshire, whilst, in several places, specimens of whose 

 hybrid origin there is no doubt, and which show several gra- 

 dations, occur, I have seen a number of others about which 

 there is much uncertainty. In places where both S. cinerea 

 and S. aurita grow, a number of intermediate forms can be ob- 

 tained, but plants of what also appears to be S. lutescens occur 

 along with S. cinerea only. These, however, grow on the banks 

 of rivers, and it is probable that they have been brought thither 

 by water. Along with them grow other plants which differ very 

 slightly from true cinerea and which may be (though this requires 

 proof) hybrids of cinerea with lutescens. In the meantime I prefer 

 to consider them as untypical cinerea. 



I have also seen specimens of S. lutescens from other parts of 

 Britain, as, e. y., from Primside Bog, Roxburgh (A. Brotherston), 

 Thirsk, Yorkshire (W. L. Notcutt), Crabtree, Devon {Archer 

 £/%*)_all labelled as cinerea ; named oleifolia, Sm.— Thirsk, 

 Yorkshire (J. #. Baker), lutescens on the cinerea side; Quintin 

 Pool, Warwick (T. Kirk), very near aurita ; named aquatica, Sm. 



Palkenham, Norfolk (W. L. Notcutt) ; Hatton, Warwick (B. 

 Bromwich) ; and Dorset (Salter). Other specimens, which I refer 

 to lutescens, are from Caithness (F. F. Linton), Worcestershire 

 (-8. F. Towndrow), Kincardineshire (Trail), Clova, Forfarshire, 

 and Derbyshire (W. B. Linton), and Surrey (W. H. Beely). 



It is probable, therefore, that S. lutescens is a species widely 

 distributed in Britain. At the same time it may be somewhat 

 l^al, since S. cinerea and S. aurita, though not unfrequently 

 associated, seem to prefer habitats of a rather different nature 

 *et moorlands in the case of aurita and river-banks in that of 

 cinerea. Wherever the two do grow in proximity (and such places 

 occur in many districts) there S. lutescens should be looked for.
