The handsome Birch which forms the subject of our plate 
is remarkable on account of its large and deeply cordate 
leaves which impart to the species a striking resemblance to 
some of the Lindens. It was originally met with by the 
lamented Mr. Maximowicz in the island of Yezo in Japan, in 
which country it was afterwards collected by Dr. Mayr on 
the Nikko mountains in Hondo. According to Professor 
Sargent it ranges northwards through Saghalien into 
Manchuria. In 1888 the late Mr. J.-H. Veitch sent a 
supply of seed of this tree from Yezo to England, thus for 
the first time introducing it into Europe, where examples 
are now to be met with in many establishments. In 1893 
Professor Sargent presented to Kew from the Arnold 
Arboretum a supply of seed received by him from the officers 
of the Imperial Forest Department of Yezo. From a plant 
Ocroper, 1910.
