There seems little reason to doubt tliat Weston's variety is the same as 

 Q. roiundijolia Lam. and Q. Ilex /?. Balloia A. DC, though the description 

 is very short, but the only form with which it could have been confused is 

 Q, Ilex var. gramnntia Loudon which is enunieraled as a distinct variety 

 by Weston.

This variety differs from typical Q, lanuginosa chiefly in its deei)ly sin- 

 uatelv lobed leaves with about 5 narrow acute lobes on each side and can 

 hardly be considered specifically distinct from the polymorphous Q. 



lanuginosa. 



As the name for the species I liave taken up Q. lanuginosa Thuillier (1799, 

 not Lamarck 1778 which is a synonym of Q, Cerris L.) in preference of 

 Q. puhescens WilldenoAV of 1796, since Willdenow states definitely under 

 Q. puhescens in S])ecies plantarum (iv, 450. 1805) Lhat the species described 

 under the same name in 1796 (Berlin. Baumz. 279) is not the same plant as 

 the one described in his Species plantarum, but a variety of Q. alba L. 

 which he now calls Q. alba y. puhescens. Without this note one may easily 

 be led to identify the Q. puhescens of 1796, the habitat of which is given as 

 southern France, witli Q, lanuginosa of Thuillier, except that Willdenow 

 describes the leaves as attenuate at the base and on the shoots sometimes to 

 8 inches long, a size never attained by the leaves of Q. lanuginosa. It is, 

 however, not quite clear what his Q. alba y. puhescens really is, possibly a 

 form of Q. hicolor,
