480 Dr. Francis Hamilton's Commentary 



quotes the Arundarbor spinosa of Rumphius (Herb. Amb. iv. 14. 

 t. 4) ; but in this I think he was mistaken, the plant of Rumphius 

 beins at times almost scandent, and even its smallest branches 

 are armed with spines ; while the Bheru is the most erect Bambu 

 that I have seen, and the spines are chiefly confined to the prin- 

 cipal stem. Rumphius himself (p. 11.) thought that the Ily of 

 Rheede was his Arundarbor fera (p. 16.), in which I entirely 

 agree with him ; and I think that the Bheru Bangsa, which I 

 have described, is the second variety of Rumphius with a lofty 

 straight stem. The figure in Rumphius (iv. t. 4.), referred to 

 by Burman as that of the Arundo fera, I cannot well reconcile 

 with the description, and doubt of its even representing any 

 Bambusa. Further, I am persuaded that the Arundarbor vasa- 

 ria of Rumphius is the Bambu most commonly cultivated in 

 Bengal, and is probably the plant which Dr. Roxburgh called 

 the Bambnsa arundinacea. I shall now content myself with men- 

 tioning the synonyma belonging to the Hi/, with such circum- 

 stances as may serve to distinguish it as a species.
