Western Szech'uan: Wa-shan, forming thickets, alt. 1700- 

 3000 m., June 1908 (No. 3408). 



A very distinct species characterized by the densely clustered short flower- 

 branchlets springing laterally from the nodes from which the leaves have already 

 fallen. 



The general appearance of the inflorescence suggests Phyllostachys rather than 

 Arundinaria but the culm is terete not with the one flattened side characteristic of 

 Phyllostachys. A remarkable character is the thick pericarp which, as Mr. J. S. 

 Gamble, who kindly confirms my determination, suggests, recalls the fruit of 

 Dendrocalameae rather than of Arundinarieae. 



Arundinaria sp. 



Western Hupeh: Fang Hsien, uplands, alt. 2000-3000 m., April 

 17, 1907 (No. 1462; 2-A m. tall, stems golden). 



Without flowers. 



This plant is in cultivation. It forms on the mountains of north-western Hupeh 

 dense thickets and with its clear golden slender stems is one of the most beautiful 

 of Chinese Bamboos. A picture will be found under No. 0111 of the collection 

 of my photographs. E. H. W.
