 SARHACENIA PURPUREA. L. Sidesaddle flower. 



Leaves decumbent, shorter than the scape, in-

The whole of this genus are plants of very singular struc- 

 ture. The Sarracenia purpurea is the only one which endures 

 our climate. The leaves, which are all radical, are formed by

 five oval, obtuse leaves, inclining to purple. Petals five, large>
