Measurements of growth of culms of Gigantochloa levis are 

 given in Table 10. This species sends up its shoots in general 

 later than do Bambusa spinosa and Bambusa vulgaris. Measure- 

 ments were started on a few shoots which had commenced to 

 develop on June 5, but only one of these shoots reached maturity

 this individual have not been included in our table on account 

 of the small size attained. In general the shoots did not com-
