Andropogon SchananfliKS (a native of Arabia, and tlie source of the true 'lemon 

 grass oil') is cultivated all over India for the .stimulating and scented oil yielded by 

 it. A. murieatus affords the fragrant roots of which tlie screens and tatties are 

 made, which in the hot winds of Upper India so largely contiibute to make life 

 endurable to the European settler, the beneficial effects being proportionate to the 

 heat and dryness of the air, so that, although much used in Calcutta, their efficiency 

 and value there is not to be compared with that developed in the parched and drier 

 region of Upper India. Other 'lemon grass oils' are yielded by A. calanms- 

 aromaiicus, A esculenium, and^. itcaranciisa, the last furnishing the celebrated Roosa 

 grass oil, and the first the grass oil of Kimar. The perfume of these oils is very 

 refreshing, and the oil itself is valuable in rlieumatism if well rubbed into the 

 aifccted part by the palm of the hand, with a little common oil to form a liniment. 

 Ceylon ' lemon oil ' is distilled, says Thwaites, from the leaves of a cultivated variety 

 of A. Martini, Roxb. Lemon grass cut up small is also used by some people to 

 flavour tea with, and if the tea happens to be musty and poor, it may perhaps 

 imjH'ovc it by disguising its shortcomings and musty taste.
