Andropogron Sorghum, Urotero.* (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 

 Christiania 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 " Kafiir-corii," which sort is particularly drought-resisting 

 [James Henderson]. The u lmphee" affords a superior white 

 food-grain. Even A. saccharatus can be only regarded as an 

 extreme form of A. Sorghum on the high authority of Prof. Hack el. 

 In Central Australia it ripens within three months [Rev. H. 

 Kempe]. Succeeds in dry regions, where .Euchlaena does not 

 come to full development. A kind of beer, called " Merisa," is 

 prepared from the seed. Many others of the numerous species of 

 Andropogoii, from both hemispheres, deserve our attention. 



Anemone Pulsatilla. Linne. 



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

 perennial herb is of some medicinal importance, acting in many 

 respects similar to aconitum. A. pratensis and A. patens (Linne) 

 are of like value, the latter extending to North- America. 



Ang-ophora. intermedia, De Candolle. 



South-Eastern Australia. This is one of the best of the 

 Angophoras, attaining a large size, and growing with the rapidity 

 of an Eucalyptus, but being more close and shady in its foliage. 

 It would be a good tree for lining public roads and for sheltering 

 plantations. The Rev. J. Tenison Woods states, that it is not 

 rarely over 150 feet high, that the wood is hard and very tough, 

 bearing dampness well, but that the many kino-particles lessen its 

 usefulness. Carefully selected, it can be employed in carpenters' 

 and wheelwrights' work. Pasture-animals of all kinds like to 

 browse on the leaves, so that it is regarded as a " stand-by " in 

 seasons of drought [A. R. Crawford]. Mr. Kirton observes, that a 

 single tree of this species or of A. laiiceolata will yield as much as 

 two gallons of liquid kino at a time ; nearly half of this consists of 

 Kino-tannic acid ^fishermen tise^ttto tan their nets [J. H. Maiden]. 

 A. lanceolata (Cavanilles) of the same geographic region is a 

 closely allied species, but its timber is more close-grained, particu- 

 larly hard and heavy. Flowers of all Angophoras much frequented 

 by the honey-bee [Ch. French]. It is averred, that occasionally a 

 watery fluid drops in dry weather from these trees, as a sign of the 

 copious absorption of humidity [Edw. Martin].
