728 ARBORETUM ET FRUTICETUM BRITANNICUM. 



Variety. Brotero, in his Flora Lusitanica, mentions a variety with variegated 

 leaves, that was found wild in Portugal. 



The tree grows rapidly, more especially when once established, and after- 

 wards cut down ; sometimes producing shoots, in the climate of London, 

 6 or 8 feet in length. It bears pruning remarkably well, at every age. Its 

 leaves are very seldom touched by insects, either on the Continent or in 

 England ; and the fossus Ligniperda and Scolytus destructor, which are so 

 injurious to the timber of many other trees, never touch either that of Celtis, 

 that of Planera Richard/', or that of Pyrus Sorbus.
