NATURAL HISTORY OF PLANTS. 



to the leaves or clearly terminal.^ Some hundred species^ are known ; 

 but on account of being reckoned twice over the number is some- 

 times made a hundred and fifty, or more. They inhabit all the 

 temperate regions of the world, and the more elevated and cooler 

 parts of the mountains in tropical and subtropical regions. 



EfTodium^ formerly united to the Geraniums, has been artificially 

 separated as a genus because its oppositipetalous stamens are sterile 

 and reduced to squamiform filaments. Their fruits present differences 

 of little value* and their organs of vegetation are the same. Some 

 fifty species are described^ iahabitiug the temperate regions. Some 

 are found in South Africa and Australia. 



Monsonia^ numbering some fifteen species,'' inhabiting South and 

 Easterfi. Africa, and tropical Western Asia, consists on the contrary 

 of Geraniums with fifteen stamens which seem to form, at the adult 

 age, five alternipetalous bundles. In each bundle is a central stamen 

 larger than the rest and superposed to a sepal, the lateral 

 stamens forming a pair at first oppositipetalous.^ This genus, which 

 has been divided into three sections,^ belongs to Southern and Eastern 

 Africa, and to the East. 



' Whence it reeulta tliat when the mflorescenoe 

 is lateral or oppositifoUus, it is often drawn up 

 and raised.
