Known only from a short note by Dr. Royle, who states that it, 

 and not A. Ivarancussa, produces the fragrant and stimulant Grass oil 

 of Namur, and who conjectures it to have been the " sweet cane " and 

 the " rich aromatic reed from a far country " of Scripture. It is used 

 in India as an external application in rheumatism, in the same way as 

 Cajeputi. It is also given as a stimulant.
