432 Mr. Bentham on the Heliamphora nutans, 



portance, as it is evident from their variableness and want of symmetry that 

 they are reductions from a normal type. 



As to the general affinities of the Order, this genus, a less complete one than 

 Sarracenia itself, does not appear to furnish any further elucidations, except- 

 ing in as far as it proves that neither the symmetry of the floral envelopes, nor 

 the foliaceous stigma of Sarracenia, are of importance. The inflorescence, 

 the only character more developed in Heliamphora, is not different from that 

 of Papaveracece, to which order, as well as to Nymphceacece, some affinities 

 have been already indicated by various botanists, from both of which Orders, 

 however, the placentation essentially removes the Sari'aceniacece. 



I now proceed to give the technical character of the Heliamphora nutans, 

 of which I have derived the generic name from e'Xoc, a marsh, and dfKpopeva, a 

 pitcher.
