XIII. — Remarks on the Growth of Bambusa arundinacea in the 

 large Conservatory, Chatsworth. By Mr. Robert Scott*. 



In the tropics the Bamboo not only grows with astonishing ra- 

 pidity, but attains a very great height, — in some instances as much 

 as 100 feetf. This, together with its feathery elegance, places it 

 in bold contrast to surrounding vegetation, and entitles it to rank 

 second to the noble Palm. But under artificial culture it is in- 

 deed seldom seen in anything like its native majesty, — the extent 

 of our horticultural structures not admitting of its full develop- 

 ment. 



In some degree at least this defect is obviated here, the Bam- 

 busa being planted out in a border of rich loam, with plenty of 

 room for its roots, and the canes likewise, in most cases, having 

 ample accommodation. So situated the Bamboo seems at home. 



* Read before the Botanical Society of Edinburgh, July 12, 1849. 

 + Mr. John Gibson, who collected in India for the Duke of Devonshire, 

 has seen the Bamboo 100 feet high.
