Geog raphical Distribution. 



Sp. simplex is a northern plant. According to Linnteus^s 

 description and Smith's assertion, n. 345. in the Fl. Lapp&n. 

 can be nothing else but this plant. Yet AVahlenberg says 

 i^Fl. Lapp. p. 822.), it is Sp. natans ; and Sp. erectum (by 

 -which he understands Sp. ramosum and simpleoc) does not 

 grow beyond Medelpadia 63" N. Lat. How shall we re- 

 concile such evident contradiction of two equally credible eye- 

 witnesses ? As Linnaeus says respecting this plant, that it has 

 from ten to twelve male flower-tufts at its top, it cannot be 

 Sp. natans. Linnaeus found this plant in the Great Calix- 

 elf, (67^), where, according to our opinion, Wahlenberg 

 never was. J. G. Gmelin found it in Siberia, in the Jenisei, 

 and in the province of Lsezk. In North America it is found 

 every where as far as the river St. Lawrence, (50^). It does 

 not seem to extend far south, for it is not met with either in 

 Greece or Tauris ; but it is found in Transylvanit\ and tlic 

 south of France, (45*').
