From the table it would appear that the period of most rapid 

 growth of any individual culm depends rather on the height of 

 the culm than on the season. 



The culms for which measurements are given in Table 8 were 

 all large or fairly large; smaller culms show slower rates of 

 growth, but mature in about the same length of time. 



In Table 9 are given measurements of the growth of culms 

 of Bambusa vulgaris. This table is constructed in the same 

 manner as the previous table for Bambusa spinosa. The rates 

 of growth are slower than those for Bambusa spinosa, as might 

 be expected from the fact that Bambusa vulgaris is a smaller 

 bamboo. These figures show even more clearly than do those 

 for Bambusa spinosa that the time of most rapid growth depends 

 more on the stage of the development of the culm than on the 

 season.
