by the mycelium of hydropsis they are invariably hindered in growth and 

 owing to the poor nutrition, they end in the producing stems that are 

 weak in a way characteristic of the malady. 



It is commonly known that among ordinary trees, when attacked by 

 a malady on their roots, show immediate signs of the trouble in their 

 crowns. With bamboos, on the contrary, the affected stems differ in 

 appearance but little from the healthy ones in the early stages of the 

 malady. Since, no cambium layer exists in bamboo, growth in the size of 

 the stem is limited to the jfirst two weeks. In later days, the stem 

 gradually grows inwardly, so that the five years old stem is not notably 

 larger than the one year old stem so far as the circumference is concerned 

 although it is far heavier and more compact. 



As to fruit-body no conclusion is yet arrived at and we must wait 

 for full researches on this subject.
