THE CKYPTOGAMIC FLORA OF KENT. 329 



tomentose externally, and clothed inside, except at the base, where 

 the acorn is attached, by a thick felt-like lining of fulvous velvety 

 tomentum ; whilst the acorn, much more oblong in form than 

 that of its ally, is of a rich deep bay brown, and even at full 

 maturity is more or less covered with a tawny wool, which can 

 only be removed by hard rubbing. None of these characters are 

 met with in Q. c/lauca, and the two trees are in my judgment 

 amply distmguished by them.
