THE FLOWER. 

 J 2. OF THE STAMENS, AND THE ARTIFICIAL CLASSES. 



64. THE stamens and pistils are situated within the floral 

 envelopes, and since one or both are always present, in every 

 species, at least, of the PhsBnogamous .plants, they were seized 

 upon by LinnsBus* as the basis of his beautiful arrangement, 

 called the Artificial System.

* Carl Von Linn6, or Linnaeus, the most eminent of naturalists, was the son of a clergy- 

 nan, born in 1707, at Rhoeshult, in the province of Smaland, Sweden. In his 24th year 

 vhile a member of the University of Upsal, he conceived the idea of that system of plants 

 which bears his name. In 1741 he became professor of medicine in the same University, 

 vnd in 1761, on account of his great literary attainments, was elevated to the rank of nobiliiy. 

 He died in 1778. To him the natural sciences are under incalculable obligations, all of 

 which he classified and arranged anew. But the science of botany, especially, is indebted 

 *> him for those discoveries and classifications, which have, more than any others, contri- 

 uted to its general diffusion. In his ' immortal work,' Species Hantarum, he enriched the 

 language of botany by a new nomenclature of species, and many new terms in the tech- 

 nology of plants, for their more accurate description.
