Abstract
“KAZINOKI” “KÔZO” and “TURU-KÔZO”, the material for making KÔZO-paper, Shifu-fabric etc., are quite different species of the moraceous genus Broussonetia, but generally they are called together by one Japanese name “KÔZO” [_??_] among the Japanese paper-makers, foresters and cultivators. I made a brief sketch on these three species of Broussonetia from the morphological and the taxonomical standpoints and also attempted to introduce concisely their various vernacular names for those who have interest in “KôZO”.
