ARBORETUM ET FRUTICETUM BRITANNICUM. 



1520. A. cordifoiia. 



A large and very handsome round-headed tree, with broad, deep green, 

 shining leaves, deeply heart-shaped at the base. It grows with rapidity in dry 

 soil, and is one of the most interesting ornamental trees that have of late years 

 been introduced. It is a most distinct species ; and, though a native of the 

 kingdom of Naples, it is perfectly hardy. It ripens seeds in the climate of 

 London, and might easily be rendered as common as A. glutinosa.

 branched. Scales of the stro- 

 biles having equal lobes, trun-

 deciduous shrub, or low bushy 

 tree. Hungary, Styria, and 

 Carinthia, on high mountains ; 

 and Germany, in the neigh- 

 bourhood of Saltzburg. Height 

 5 ft. to 6 ft. Introduced in 

 1820. Flowers greenish brown ; 

 March and April. Fruit brown ;. 

 ripe in August. 



This plant is considered by 

 many botanists as intermediate 

 between the alders and the birches. 

 It agrees with the alders, in hav- 

 ing the peduncles of the female 

 catkins ramose; and in general 

 appearance it resembles the A'lnus incana in a young state : but it belongs 

 to the birches, by the parts of its fructification, and by the somewhat greater 

 number of its stamens.
