It is commonly found growing on mountains and hills and also in 

 fields in the middle and northern parts of Japan, and the culm is most 

 useful in this country. The culm is smaller than the type, and the leaves 

 are also smaller and narrower, having usually more obtuse or rounded obtuse 

 bases and more abruptly acuminate apex. This bamboo is most luxuriant 

 in Mt. Hakone and its vicinities ; on this account it is generally called 

 Bakone-dake.
