Andropogon refractus, R Brown. 



North and East Australia, Polynesia. Mr. Bailey observes of this 

 perennial grass, that it is equally excellent for pastures and hay, 

 and that it produces a heavy crop during summer ; the root is 

 fragrant. 



Andropogon saccharatus, Roxburgh.* (Sorghum saccharatum, 

 Pers.) 



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

 as a fodder-grass. Produces of all grasses, except the Teosinte", the 

 heaviest fodder-crop in warm climes. 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. Caffrorum, Kunth). The plant can be advantageously utilised 

 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. General Le 

 Due, Commissioner for Agriculture at Washington, states, Mr. Seth 

 Kenny, of Minnesota, obtained from the " Early Amber" variety 

 up to 250 gallons of heavy syrup from one acre of this Sorghum. 

 The stem can be used as a culinary vegetable. 



Andropogon schoenanthus, Linne. (A. Martini, Roxb.) 



South Asia and Tropical Australia, extending to Japan. A scented 

 grass, allied to the Indian oil-yielding Andropogons. The medicinal 

 Siri Oil is prepared from the root. A similar species occurs in arid 

 places of the interior of North Australia. 



Andropogon scoparius, Michaux. 



North America. Takes permanently hold of sandy or otherwise 

 poor land, and is regarded as one of the best forage resources of the 

 prairies. 



Andropogon sericeus, R. Brown. 



Hotter regions of Australia, even in desert tracts, also extending to 

 New Caledonia and the Philippine Islands. A fattening perennial 

 pasture grass, worthy of praise. 



Andropogon Sorghum, Brotero.* (Sorghum vulgare, Persoon.) 



The large Indian Millet or Guinea-Corn or the Durra. Warmer 

 parts of Asia. A tall annual plant. The grains can be converted 

 into bread, porridge, and other preparations of food. It is a very 

 prolific corn Sir John Hearsay counted 12,700 seeds on one
