ON THE CARBOHYDRATES OF THE SHOOTS OF SASA PANICULATA. 259 
such or only in combination with glucose molecule in the form of sucrose, 
we have not sufficient data to decide and the question remains to be solved 
in future. 
Summary. 
1 ) The principal constituents of the shoots are carbohyd- 
rates which form about 5 0 percent of the dry matter. 
2) The chief carbohydrates of the shoots are pentosan, c e 1- 
lulose and sugar. Gal acta n, methyl pentosan and 
starch are not present. 
3) Pentosan of the shoots is made up of both xylan and 
araban, the former, however, predominating in amount 
over the latter. 
4) Glucose and sucrose seem to compose the principal sugar 
in the shoots; the former is present in much larger 
quantity than the latter. 
In conclusion, the authors wish to express their hearty thanks to Prof. 
K. Oshima for the valuable suggestions he has given in carrying out this 
research.
