Andropogon citratus, Candolle. 



The Lemon Grass of India. It yields an essential oil for 

 perfumery; besides it is occasionally used for tea. This 

 applies as well to Andropogon Nardus, L., and some allied 

 grasses. 



Andropogon Haleppensis, Sib thorp. 



South Europe, Orient. A rich perennial grass, cultivated 

 often under the name of Cuba Grass. 



Andropogon Ivarancusa, Eoxb. 



One of the fragrant grasses of North India, much used like 

 A. Sho3nanthus. 



Andropogon Martini, Roxb. (A.flexuosus, Nees.) 



On the mountains of India. The fragrant Citronella Oil is 

 distilled in Ceylon and elsewhere from the leaves of this 

 species. General Martin observed, that cattle are vora- 

 ciously fond of this grass ; but it imparts its fragrance to 

 meat and milk. 



Andropogon muricatus, Eetz. 



India. A Swamp-grass, with delightfully fragrant roots. 



Andropogon nutans, L. (Sorglimi nutans, Gray.) 



North America. A tall, nutritious, perennial grass, content 

 with dry and barren soil. 



Andropogon SaCCharatllS, Ttoxb. (Sorghum saccharatum, Pers.) 

 Tropical Asia. The Broom-Corn. A tall annual species, 

 splendid as a fodder grass. From the saccharine juice 

 sugar is obtainable. A sample of such, prepared from plants 

 of the Melbourne Botanic Garden, was shown at the 

 Exhibition of 1862. This Sorghum furnishes also material 

 for a well-known kind of brooms. A variety or a closely 

 allied species yields the Caffir Corn (A. Caff'rorum, Kunth). 

 The plant can be advantageously utilized for preparing 

 treacle. For this purpose, the sap is expressed at the time 

 of flowering, and simply evaporated ; the yield is about 

 100 gallons from the acre. In 1860, nearly seven millions 

 of gallons of sorghum treacle were produced in the United 

 States.
