iv ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
specimen (160 ft. long) was originally in the Museum of the East India Company, 
the botanical contents of which came to Kew when the possessions of that Company 
were taken over by the Government; this specimen may be from India, but it is 
just as likely to have come from the Malayan Peninsula, or from Sumatra or from 
Java. The longer one (369 ft.) clearly came direct to Kew from Mr. W. Ferguson 
of Colombo, and there is no doubt that this specimen is a Ceylon one, What 
particular species these specimens represent it is very difficult to say. 
Prof. H. Baillon in the ‘‘ Monographie des Palmiers” {“ Histoire des Plantes? 
Vol. XIII (1895) p. 326] revived the generic name Aotang, used by Linnaeus in 
the “Flora Zeylanica (1747) 209, in substitution for Calamus, but Rotang Baill. 
includes both genera Calamus and Daemonorops. 
The following are the species of Calamus mentioned by Baillon under the 
name of /?otang at pp. 299, 300.
