This Bamboo was once an essential element of Japanese garden shrubs. 

 But it began to flower from 1905, and within 10 years it disappeared entirely 

 from the gardens. In those days it fruited well. Some have succeeded 

 in raising seedlings; these, therefore, may exist in Japan, but I do not 

 know where they are at present.
