insist iiix)n tbe existence of a relationslup between the Moringacese and tbe 

 Geraniales. Pax considei-s tbat it is probably best to regard the family as a 

 middle member between the RhceadinesB and the L^iminossB. 



Series XXXI. Sarraceniales 



111 SarraceniaceaB^^ : Clearly related to the Droseraceae in floral sfcrac- 

 tnre. The family is placed near the Papaveraceae by Bentham and Hooker on 

 account of the staminal cycles and styles. On the other hand its relation to 

 the Nymphseacese is incontestable, as can be seen in the numerous stamens, in 

 the insertion of the leaves on the stem, in the one-flowered scape and in the 

 spiral aiTangement of the sepals. But, INIacfarlane'^ inclines to look for even 

 closer natm-al afl5nity with the Cistifloraj than with the Papaveraceae and 

 Nymphfeaceoe. 



112 Nepenthaceae^^ : R. Brown, Brongniart, LmK and Endlicher 

 put this family close to the Cytiueae and Aristolochiacese, which agree with 

 the Nepeuthacese in the perianth, in the entrorse anthers, in the many-seeded 

 capsules and probably in the stigmata. Lindley, Grisebach and Eichler 

 place it near the Droseraceas and San-aceniacese in consideration of the fniit 

 and seeds. The Nepenthaceae and Sarraceniaceae have considerable aflfinities 

 with the Droseracese, and all of these seem to stand in a position intermediate 

 between the Papaveracese and the Cistaceae*^. 



113 Droseraceae'-^ : As far as the hypogynous insertion and the parietal 

 jjlacenta are concemed, the family is comparable with the Cistaceae and Vio- 

 lacese ; but in the perigynous insertion and in the locular ovaiy (of some 

 species of the family) it comes rather close to the Saxifragacese. 



Series XXXII. Itosales 



114 Podostemonaceae*^' : It seems reasonable to believe that the family 

 is rekted to the Saxifragacese, as there is agreement in the hj-pogynous and
