Naturalisation in Extra-Tropical Countries. 45 



Andropogon saccharoides, Swartz. (A. argenteus, De Candolle.) 



Pronounced by Leybold to be one of the best pasture-grasses of 

 the Cordilleras of Chili. 



Andropogon Schcenanthus, Linn. (A. Martini, Roxburgh.) 



Southern. Asia, extending to Japan, also in Africa. One of the 

 " Lemon-grasses." It will live in arid places. The medicinal Sirri- 

 Oil is prepared from the root. The Australian A. bombycinus 

 (R. Brown) approaches in affinity this species. 



Andropogon scoparius, Michaux. 



North- America. Takes permanent possession of sandy or other- 

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

 the prairies. 



Andropogon sericeiis, 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. Yields enormously during the dry 

 summer months [Fr. Turner]. Proved one of the best pasture- 

 grasses in North- Western Australia [Isaac Tyson]. 



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



The large "Indian millet" or "Guinea-corn" also "Durra." 

 Warmer parts of Asia, but according to Alph. de Candolle perhaps 

 indigenous only in tropical Africa. It matures seed even at Christi- 

 ania in Norway [Schuebeler]. 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 plant ; it is particularly valuable for green fodder. The panicles 

 are used for carpet-brooms, the fibrous roots for velvet-brushes. The 

 grain of this millet is in value superior to that of A. saccharatus. A 

 variety (A. caffrorum, Kunth) yields the " Kaffir-corn," which sort 

 is particularly drought-resisting [James Henderson]. The "Imphee" 

 affords a superior white food-grain. Even A. saccharatus can be 

 only regarded as an extreme form of A. Sorghum on the high autho- 

 rity of Prof. Hackel. In Central Australia it ripens within three 

 months [Rev. H. Kempe]. Succeeds in dry regions, where Euch- 

 laena does not come to full development. A kind of beer, called 

 " Merisa/' is prepared from the seed. Many others of the numerous 

 species of Andropogon, from both hemispheres, deserve our attention. 



Anemone Pulsatilla, Linne. 



Europe and Northern Asia. On limestone-soil. This pretty peren- 

 nial herb is of some medicinal importance, acting in many respects 

 similarly to aconitum. A. pratensis and A. patens (Linne) are of like 

 value, the latter extending to North- America.
