244 CHINESE ECONOMIC TEEES 



About 20 species are recognized, all in the temperate northern 

 hemisphere. About 20 species occur in China. Linden or Basswood is 

 the common English name. 



The wood is light in weight, used in interior finish and for wooden-

 and in Kussia, Sweden and Cttina it is woven into shoes and sandals.
