very important and extensive museums, herbaria, arid libraries, and 

 one large, fine greenhouse. The systematic plantations occupy the 

 larger portion of the tract, and special areas are devoted to the culti-

 native trees, and to groups illustrating plant geography. The garden 

 and associated laboratories provide equipment for the prosecution 

 of all lines of botanical research. 



7. A Botanical Garden in Buenos Aires. 



[Extracts from Bulletin of International Union of American Republics, June, 1909,, p. 



1055.] 



20 acres in area ; founded, 1892. 



It is divided into 14 sections, each of which is devoted to the flora 

 of a district region. 



Of the three styles of garden development, i. e.. French, English, 

 and South American, the English seems to draw the most attention. 



The tipa tree, a species of acacia, which will thrive in any soil, is 

 seen to perfection here. Its bark contains a poison which renders 

 it invulnerable to insect enemies. 



There is a large collection of ferns, cactus, water lilies, orchids, and 

 trees, and there are two conservatories. 



8. The Belgian State Botanical Garden, Brussels. 



[Extracts from publication of the Department of Agriculture, Brussels, Fred Tilbury, 

 English printer, 16 Rue d'Edinbourg, 16.] 



10 acres in area; established in 1826. 



These gardens came into possession of the State on the 1st of July, 

 1870. Since that time, instead of remaining an almost exclusively 

 horticultural establishment, the garden has risen to the dignity of 

 of a scientific institution, devoted to botany, and the headquarters of 

 the Botanical Socitey of Belgium. 



The garden now comprises four sections: The herbaria, museums 

 and vegetable paleontology, experimental section, cryptogamy and 

 vegetable pathology. 



The greenhouses are connected with section I; the departments and 

 temperate houses with section III. Special areas are devoted to orna- 

 mental and economic plants.
