A North American genus, partly maritime, not extend- 

 ing, beyond the Alleg-hany mountains. Tiie opportunity 

 otexaminingthe seeds of this genus have escaped rne for 

 the present, but there can scarcely exist a doubt of the di- 

 rect asb-oclalion of Sarracenia with any order which can 

 include the genus JVvptiar. The singular deformity in the 

 leaves ought not to operate in any material respect 

 against its admission amongst genera of so different an ex- 

 ternal aspect. In JKepenthes the ascidia or tubes are 

 merely an appendage to the true leaves; and in the Cepha- 

 lotus of New Holland we have an instance of leaves and 

 ascidia produced separately, both plants of very distinct 

 orders from the present, it is probable that other genera 

 will also be discovered at some period in the vast and 

 unexplored regions of the v/orld, furnished with these sin- 

 gular appendages. 



568. NUPHAR. Smith, (Yellow Pond-Lily.) 

 Calix 5 or 6-leaved. Petals many, minute, 

 inserted with the stamina upon the receptacle, 

 N externally nectariferous. Stigma orbicular, ra- 

 diated, sessile. Capsiiie cal*nose, many-celled, 

 many-seeded, superior. 



Herbaceous aquatic plants; with alternate floating and 

 sometimes emerging leaves, more or less semiorbicular- 

 ly cordate, at first Involute towards the centre of the up- 

 per surface which resists the admission of water; petioles 



ture, surrounded more than half-way by a dilated and finely re- 

 ticulated lobe, more or less connivent over the surface of the 

 orifice; this operculoid lobe is covered with rigid hairs bent 

 downwards like the teeth of a card; the entrance of the orifice 

 for a few lines is very smooth and appears resplendent like vel- 

 vet, but is not polished; the Interior of the tube for about half 

 its length is not only smooth but poUshed, the lower half then 

 presents the same retrorse rigid hairs as the operculum but 

 Tsomewhat longer; — the insect descending thus far without 

 meeting with any opposition, is now arrested on its return, and 

 becomes entangled by the feet; if it should succeed to extri- 

 cate itself in an exhausted state, it is again precipitated into 

 the former abyss inevitably to perish!
