 being tunned into a tul ly inflated in the middle, and 



the lamina, which is small, generally inflected over the orifice.

 June. Can. to Geo. in swamps. 1 — 2 feet. 



2. S. hu'bra, (Walt.) Leaves slender, elongated, with the wing linear ; 



throat not contracting. Lamina erect, mucronate, hairy on the inner 

 surface, contracted at the base. Petals obovate, narrowed at the base.

3. S. fra'va, (L.) Leaves large, with throat, expanding, scarcely any 

 wing. Lamina erect, reniform, with reflected margins ; base con- 

 tracted, mucronate. with purple veins. Petals obovate-oblong. Stig-

Croom thinks the 8. Catesbeei of Elliott is only a variety of the S. 

 flava. — Sill. Jour., vol. xxviii. p. 1

 Tube spotted on the back. Lamina arched; wing slightly dilated. 

 Petals obovate-spatulate, inflected over the stigma. — Yellow. U. Ju. 

 and (Jar. in pine-barren ponds. 



This genus affords a striking example of a great modification of the petiole, since 

 - do doubt that the tube part is the petiole, and what we called the lamina, the 

 trne lamina of the leaf. These tubes are generally filled with water, which is sup- 

 by the plant, and this always contains dead insects. The tube 

 couid not have been formed in a better manner to accomplish a given end. than this is 

 iiarine secretion which surrounds the orifice decoys insect3 

 to the tube, and the water entices them in. There are hairs pointing downward, so as 

 to permit an ea^y descent, but makes the egress difficult.
