* The dilitata of most authorg. 



t Lindley establishea a family, Sarracenia. in which this is the only genus ; he considers it to be allied to 

 PapaveracesE, on account of ita dilated stigma, its indefinite nun)ber of stamens, and small embryo lying at 

 the base of copious albumen. He also thinks it nearly related to Droseracese, or to whatever family the 

 Dionsa may be placed in. The pitcher-form leaf of the Sarracenia is analogous to the dilated foot-stalk of 

 tlie Dioncea, and the lid of the pitcher in the former leaf is represented by the irritable lamina in the latter. 

 In the structure of its leaves, the Sarracenia is related to the family Nepenthete, containing the pitcher- 

 plant. 



: Referred by Lindley to Droseracete.
