52. OF THE STAMENS, AND THE ARTIFICIAL CLASSES. 



G4. The stamens and pistils are situated within the floral 

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

 species, at l^ast, of the Pha^nogamous plants, they were seized 

 upon by Linneeus *; as the basis of liis beautiful arrangement, 

 called \the Artificial System/

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

 nan, horn in 1707, at Rhffishult, 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 

 (vhich hears his name. In 1741 he became professor of medicine in the same University, 

 ind in 17G1, on accoiint of his great literary attainments, was elevated to the rank of nobiUty. 

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

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

 I'o him for those discoveries and classifications, which have, more than any others, contri- 

 iiuled to its general diffusion. In his ' immortal work,' Species Plantarmn, 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.
