CHIMONOBAMBUSA Making, gen. nov. 



BAMBUSA Auct. pro parte, non Schreb. 



ARUNDINARIA Auct. pro parte, non Michx. 



PHYLLOSTACHYS Auct. pro parte, non Sieb. et Zucc. 



The diagnosis will appear in the forecoming page. 



This genus is more closely allied to Avundinaria than to 

 Bawbusa and Phyllostachys. The rhizome is monopodial. 

 The feature of the inflorescence, spikelets, and flowers is similar 

 to those of Arundinaria, and widely differs from those of Bam- 

 busa and Phyllostachys. The branches on the culm are in 

 threes to each node. The culm is ringed often with the 

 short ffirial roots at the nodes ; sprouts come up in the be- 

 ginning of winter; culm-shcath is membranaceous and mar- 

 moraceously purple-maculate ; microphjll is minute or mcon- 

 spicuous.
