>S^. spuria, Willd. — To this — which is S. LapponunixS. 

 Arhiscula — I referred in my previous notes a willow (on 

 sheet 330) from Glen Dole, Clova, and mentioned that the 

 Eev. E. F. Linton had found it in Clova more recently. I 

 have lately seen a series of similar specimens collected in 

 Clova by Eev. W. E. Linton, and now perceive that Mr 

 Linton's specimens are hybrids of Lapponuni with herhacea 

 (=:8. sohrina, B.W.) and not with Arhuscula. I suspect 

 therefore that the specimen on sheet 330, which has leaves 

 only, is the same. In the meantime, at any rate, it must be 

 considered as doubtful.
