98 Observations on the genus Sarrucenia ; 



leaves of Sanacenia have a lateral slit, which prevents their 

 holding any considerable quantity of water. This, however, ~ 

 is not the case ; and nothing is more common than to find the 

 tubes in some species (especially in S. purpurea and S. flava) 

 half or two-thirds filled with water. 



The genus Sanacenia is, as is well known, exclusively North 

 American, no species having been detected west of the Alle- 

 gany mountains. They are mostly found in the sphagnous 

 swamps, savannas, &c. of the southern Atlantic states, a single 

 species (S. purpurea) being, however, common in the northern 

 states, extending even to Newfoundland and Hudson's Bay.
